Welcome aboard Mariah! You have chosen one of the most popular and best equipped boats

in the San Juan Yachting fleet. We have maintained her in a like new condition and are continually

upgrading and adding new features. We trust you will take care of our investment as if she were

your own. Please let us know if you find anything missing or in need of improvement. While using

or reviewing these notes, please feel free to mark corrections, and make suggestions and

improvements. Your constructive criticism will be appreciated. We hope you enjoy cruising with

Mariah as much as we do. Thank you, Scott and Susie Larson (Owners) [email protected]m

INTRODUCTION

Mariah is a 2004 Nordic Tug 42, powered by a Cummins diesel engine, with a HP rating of 450

@ 2600 RPM. It can carry 600 gallons of fuel and 200 gallons of water. At a time when we are

all conscious of high fuel prices, the Nordic Tug provides a real bargain. According to Cummins

Northwest, Inc. data, the 42 Nordic Tug can provide hours of cruising fun at reasonable speeds

with very limited fuel consumption.

NOTE: All system operation instructions assume you have all AC and appropriate DC circuit

breakers powered. Note: Red lettering indicates safety items or key operational notes.

These notes are prepared for Quick Reference. Nordic Tugs, Inc. has provided an operation

manual for the 2004 model. Much of the information is taken from the Tug Operator’s

Manual but has been condensed for quick reference. For more in-depth systems information

please consult the owner’s manuals and component manufacturers’ installation/operation

manuals that came with the boat. They are large red notebooks located under the hinged

instrument panel in the pilothouse. The Owner’s Notes assume that the charter

guest/operator is experienced and competent in the safe operation of a 36,000 pound, 44 foot

powerboat, and knowledgeable of boating rules and regulations. These notes do not attempt

to anticipate every situation or occasion that may arise. Chances are good you will never

have to accomplish any of the detailed procedures we have included in our notes. (i.e.

changing a fuel filter etc). We have included this type of information in our notes to give you

the peace of mind in knowing there are instructions in the unlikely event you should need

them. These notes are not all-inclusive but should be adequate under most situations.

Exercising reasonable care and good judgment in the handling and operation of the boat is

the best way to ensure a trouble-free experience.

9 Key Nuances to remember when operating Mariah

1. Checking the oil: Remember to properly seat all dipsticks after checking oil levels. If not

seated, oil will spray out and make a mess.

2. Securing the tender: When returning the Tender, remember to install the two aft and

one forward tie-down straps and the stabilizer bar if you anticipate heavy seas.

3. Icemaker: To save the batteries, turn the ice maker off when anchored.

4. Connecting to shorepower: Deselect “INVERT” on the Xantrex inverter panel (office

station) when shore power is connected. (Prevents battery depletion if shore power

fails)

5. Electric heaters: Unplug all three electric heaters when NOT connected to shore power.

Otherwise the inverter will attempt to power the heaters and will deplete the batteries

and damage them.

6. Window shades: When raising and lowering the shades in the pilot house, use two

hands pulling in opposite directions on the cords. This will relieve stress on the shade

clutch and mounting assembly. The salon shades are a new style without cords.

7. No metal under office seat: Do not store any metallic items under the office station seat

or on the floor in front of the seat. The ships auto pilot compass receives its directional

input from an electronic compass under the seat. Inputs can be affected by metal

objects in close proximity.

8. Tender drain plug: open the drain plug switch on the steering wheel panel when the

tender is stowed. (Remember to close it before launching the tender). This will help

prevent water buildup and corrosion of electrical components in the tender.

9. Tender outboard: Make sure the outboard motor on the tender is tilted full up and

steering wheel full left. If not, the lower unit will splash seawater into the tender and

can damage the electrical box and connectors. On one occasion a charter guest left it

down and sea water nearly filled the tender requiring a complete rewiring of the

systems. You will never do a starboard docking because the outboard will hit the dock.

PREPARING FOR DEPARTURE

1. ENGINE ROOM CHECKS should be performed daily, before cruising.

At the office station, turn ON the BILGE Lights. Enter the engine room aft of the galley through

a hatch in the floor.

Note: All fluids have been checked by a maintenance professional prior to your

charter and it is very unlikely that these fluid levels would require servicing during

your charter. However, it is strongly recommended that you do a daily engine

room inspection looking for evidence of oil or other fluid leaks.

Check the oil level in the engine. There are 2 dipsticks. One on the port and starboard sides of

the engine. Either one can be checked. The port side is easier to access. The oil level on the

dipstick should be between the hash marks. If the oil level is low:

•Add oil from the blue plastic jug marked Delo 400 15/40 SAE, using the

funnel found in the replacement fluids bin stored in front of the engine.

•DO NOT OVERFILL THE OIL CAPACITY of the engine. It only takes 2 quarts

to fill the oil supply from the lower line to the upper line on the dipstick. You will

likely never need to add oil.

•When replacing the dip stick ensure it is properly seated. (Down to the yellow

tape line.) If not seated, oil will spray out making a mess.

Check the coolant level of the white plastic recovery reservoir mounted on the forward bulkhead

in front of the engine. (aka “plastic jug”) The jug should be half full. If the coolant level is low:

1. Add some pre-mixed engine coolant to the recovery reservoir.

2. The pre-mixed engine coolant marked 50/50 ENGINE COOLANT is located in

the “Replacement Fluids” bin.

Checking the oil level in the generator. The generator has a diesel engine requiring the same

care as the main engine. The generator is self monitoring and will auto shut down for a number of

reasons and provides a sequence of flashing lights that will identify the cause, (see the owners

manual in the pilot house) If low oil is suspected, remove the rectangular panel on the FRONT

SIDE of the generator to access the dipstick. The oil level on the dipstick should be within the

hatch-marked area on the stick. If the oil level in the generator is low:

1. Open the OIL FILL to the side of the dipstick.

2. Add oil from the blue plastic jug marked Delo 400 15/40 SAE, using the funnel

from the bin marked “Replacement Fluids.” Be careful not to overfill.

Check the coolant level in the generator. The generator’s diesel engine uses coolant just like the

main engine. A plastic coolant recovery reservoir (aka “plastic jug”) is mounted on the port side

of the generator. Visually check that the coolant level shows approximately 2 inches when the

engine is cold and 6 inches if hot. If the coolant level in the generator is low:

1. Add coolant to the recovery reservoir to the appropriate level, being careful not to

overfill—the coolant needs an opportunity to expand.

2. Use the pre-mixed 50/50 ENGINE COOLANT located in the bin marked

“Replacement Fluids.”

Check the RACOR fuel filters for water or contamination. Few things you do are as

important to your safety on the water as having uncontaminated fuel going to the engine! As you

enter the engine room look on the aft end of each fuel tank where you will find a RACOR fuel

filter for each tank.

•Make sure both filters are free of contaminants or water. Look through the glass

at the liquid in the bottom of each filter. You don’t want to see contaminants or a

5/7/20

separation of fluid in the bottom. (Water is heavier than diesel fuel and will

collect at the bottom of the glass bowl if there is water in the fuel.) IF YOU SEE

CONTAMINANTS OR LIQUID SEPARATION, you want to remove them

without removing all the fuel in the glass bowl:

1. With a collection container in place (stored behind the generator), open

the black drain by partially unscrewing the valve at the bottom of the

glass unit to evacuate just the water or contaminants, and then quickly re-

tighten the drain.

2. If the vacuum gage at the top of the filter approaches the yellow range at

cruise power, the filter should be changed. Please advise San Juan

Yachting if you should observe this condition.

3. The Generator has two fuel filters. One mounted on the aft port bulkhead

and the other on the engine itself. The are changed out each season and

require no other maintenance. Spares are available in the spares bin if

needed.

Complete a visual check of the engine room for leaking oil, fuel, or coolant, loose items that

should be secured, or anything unusual.

Verify that all seacocks are open, especially the main engine cooling seacock. They should be

in the open/vertical position.

Make sure that the SEAWATER STRAINERS for the engine and generator are free of

seaweed or debris. The engine sea strainer is a large bronze unit with a glass-enclosed section

that houses a strainer. It is mounted aft of the engine near the engine room entrance and is

connected to the seacock with a large black hose

1. Using the flashlight, which is stored in an open box on the aft bulkhead next to

the toolbox, check to see if the strainer is clear and not plugged with seaweed or

debris before every start.

2. To clean the strainer, close the seacock (lever horizontal), unscrew the top with

the flat bar laying next to the yellow tool box, lift out the basket, swish it back

and forth in the orange bucket filled with clean water, and then reinstall it. There

is an orange bucket in the lazarette that can be filled with clean saltwater. Use

the bucket to prevent dropping the strainer overboard!

3. REOPEN THE SEACOCK!!

4. Note: We have rarely experienced the need to clean the strainer. Avoid

driving through large patches of sea grass and you should be fine.

5. Make sure that the seawater strainer for the generator is free of seaweed or

debris. Use the same procedure as above. It is a smaller unit similar to the

engine strainer and is located on the left side (facing aft) of the generator.

6. Remember to REOPEN THE SEACOCK!!

When you have completed the engine room checks, turn off the engine room lights at the office

station breaker panel labeled BILGE LIGHTS. Failure to do so may needlessly deplete the

batteries.

DISCONNECT SHORE POWER

1. At the OFFICE STATION breaker panel, turn OFF the main AC gang breaker labeled

SHORE POWER. All remaining AC breakers may be left on.

5/7/20

2. On the dock, first turn OFF the shore power circuit breaker at the pedestal, and then

disconnect the yellow electrical cord from the dock power.

3. On the boat, disconnect the yellow electrical cord and store the cord coiled in the cord

bag in the Lazarette. Caution: Always DISCONNECT from the SHORE-END and ---

CONNECT from the BOAT-END---to avoid moving a LIVE cord!

TURN ON DC/BATTERY POWER

Battery power should automatically be supplied to the DC systems when you disconnect

AC power provided the DC breakers are on. All DC breakers may be left on with the

exception of the following breakers that should be turned on only when using that system and

when done turn them off.

1. BILGE LIGHTS

2. SEA WATER WASHDOWN

3. OIL CHANGE PUMP.

CLOSE ALL PORT HOLES AND HATCHES that might permit water to enter the interior,

especially during rough seas and windy conditions.

CHECK AROUND THE BOAT

Review the exterior area around the hull to confirm that there are no obstacles in the water or

loose items that should be secured.

HELM CHECKLIST

Check the fuel level at the “Tank Tender” gauge at the helm, and / or the sight tubes on the fuel

tanks. The tanks should be full on day one.

See fueling instructions below if fuel is needed.

Check the water level.

1. Insert the key in the ignition slot and turn to the ON position. Note the water level on the

gauge at the office station or the sight tube on the water tank in the lazarette, then TURN

THE KEY OFF!

2. See instructions below for adding water, if necessary.

Check that all breakers at the helm station are on except the 3 SPARE breakers and the

WINDLESS, FUEL TRANSFER, DC REFRIGERATOR (top deck freezer) and CAMERA

breakers. Turn the windless breaker on only when you use the system then turn it off for

safety.

Note: The Aft Camera and DC Refrigerator (top deck freezer) and fuel transfer should be off

unless you plan to operate those items.

Start up the Ray Marine depth sounder by pressing and holding the button in the lower left-

hand corner of the screen until the screen comes on.

Turn on the Ray Marine GPS chart plotter by pressing and holding the red PWR button for 3

seconds, the display will comes on after a brief period.

There are two Radar units, the primary radar is viewed by selecting a radar display page on the

chart plotter and following the start up instructions displayed there. The unit mounted left of the

chart plotter is a back up GPS chart plotter and radar. Use it only if there is a problem with the

5/7/20

primary chart plotter. If both units are on it creates a low voltage condition and one or both units

may not be fully functional.

Turn on a VHF radio. (two VHF radios are installed)

1. Check the weather channel.

2. Turn on Channel 16.

GETTING UNDERWAY

Make sure that the shift lever is in the neutral position.

Turn the start key to ON. An alarm will sound (low oil pressure). Wait for the engines air heater

to preheat the air. The voltmeter will drop below 12 volts while the system operates (about 15

seconds). When the voltage returns to 12 volts the preheat cycle is complete. (The oil light may

come on but should go out once you start the engine.)

When preheating is complete, push the START button while the key is in the ON position to

start the engine. Note: “Do not crank engine for more than 30 seconds, wait 2 minutes to allow

the starter motor to cool down before restart attempt.”

Let the engine idle for about 5 minutes or until the engine coolant temperature gauge reads above

100. Note: During warm-up at idle, the voltmeter will register about 12 volts. The temperature

indicator will not show any indication of heat until the engine has been running for several

minutes. Keep the engine below 1000 RPMs for five minutes, as the preheater cycles on and off as

needed during this time period. RPMs over 1000 block the preheating function.

Turn on the bow thrusters by pushing the 2 ON buttons simultaneously. The amber light

between the buttons will come on. Toggle the joysticks momentarily in both directions to

ascertain that the thrusters are functioning properly.

1. The thrusters are used primarily in maneuvering at or near the dock. In open

water while underway, the thruster is not effective.

2. The thrusters will turn off automatically after a period of non-use. Restart in the

same manner.

3. The thrusters may overheat and stop after 3 minutes of continuous running. After

a brief cool-down period, they will reset.

4. If a thruster is inoperative, check the large red shut off switch in the lazarette for

the (stern thruster) or the red shut off switch located under a panel beneath the

mattress in the master stateroom for the bow thruster.

Check wind and current directions.

Use the thrusters to control the movement of the bow and stern while operating the throttle in

short applications of forward or reverse, pausing in neutral, as you maneuver in the marina. Note:

when using reverse, the STERN WALKS TO STARBOARD.

CRUISING

When clear of the marina, make sure all mooring lines, fenders and anything loose are stowed.

Operate the engine at 1000 rpm for warm up. (5min.)

1. After a 5 min. warm up operate the engine no faster than 1300 rpm until the coolant

temperature reaches 140 degrees. You will probably operate at 1100 to 1350 rpm, as this

is very economical and quiet. 1350 rpm is the “sweet” spot. Above that setting fuel burn

goes way up without much corresponding speed increase.

5/7/20

2. Please make power changes slowly, rapid power changes can put great stress on engine

and drive components. It is advisable after cruising for 4 hours or more at economical

speeds (1100 to 1500 RPM), to run the engine at 2400 RPM for at least 5 min. prior to the

end of the cruise day. This helps to clean out carbon deposits in the engine. At the end of

the run-up slowly and smoothly reduce power as you approach your destination and allow

at least 5 minutes for cool down before shutting down.

3. According to Cummins Northwest, Inc data, at reasonable speeds the Nordic Tug 42 has

very economical fuel consumption.

5. Volts should read between 13 and 14 at normal cruising.

6. Water temperature should be between 160 and 165 degrees.

7. Oil pressure should range between 30 and 100 depending on RPMs.

8. Vacuum gauges for the RACOR fuel filters should read below 7 while cruising.

5/7/20

*** RAW WATER ALARM***

Mariah is equipped with a raw water alarm located at the helm. The alarm will activate a

light and a horn when the temperature of the wet exhaust pipe starts to increase toward and

unsafe level. This could occur if the seawater intake or the sea strainer become clogged

with vegetation or other debris. The alarm will trigger before other indications of overheat

occur thus saving costly engine damage. If the alarm sounds and you are not threatened by

immanent grounding, shutdown the engine and investigate.

1. Check the sea strainer and clean if required.

2. Attempt to operate the boat at a reduced rpm.

If the alarm continues it may be a failed raw water impeller. This is unlikely as they

are replaced annually. However, should it fail, there is a replacement

impeller in the spares bin in the engine room. Call San Juan Yachting on your cell

phone or VHF channel 79a and request assistance. The tender can be launched and

used to tow Mariah if there is no other option.

RETURNING TO DOCK

Fenders out and….

•On docking side of the boat, (port side is only used because of the dinghy

outboard)

•At appropriate level for the dock.

The engine cool down period (the last 5 minutes) should be at slow speeds to allow the engine to

cool down before shut off.

1. Once docked and the mooring lines are secure, turn off the engine.

2. Shut down the Ray Marine multifunctional displays by pressing the red power button

in the lower left corner and holding for the countdown on the screen. Please re-place the

screen covers on all the screens as direct sunlight can damage them.

3. There is no need to turn off the breakers at the DC POWER breaker panel next to the

helm station. Do not shut down electronic equipment ie. Chart plotter or depth sounder

with the circuit breakers...use the red power buttons or damage could occur.

•Note: The autopilot wireless remote control is recharged by a cord located below

the dc power plug on the starboard side of the instrument panel. The battery

charge state of the remote can be read on the left side of the screen and is

represented by a number of bars. The autopilot c/b must be on for power to

charge the remote. Depending on use, one charge should last 2-3 days.

unit counts down. Use the same button to turn the unit on.

•CAUTION: If using the remote outside of the pilothouse please use the attached

lanyard and wear it around your neck. The remote costs over $400 and could be

easily lost overboard.

5/7/20

CONNECTING TO SHORE POWER

1. At the OFFICE STATION electrical distribution panel, make sure the AC gang circuit

breaker marked SHORE POWER is in the OFF position.

2. Take the bright yellow electrical cord located in the Lazarette and connect it to the

receptacle located forward of the starboard helm door. Line up the prongs, insert the plug,

turn it to tighten.

3. Locate the power supply on the dock; making sure that the breaker on the dock is in the

OFF position. The yellow electrical cord is 30 amps. Check the amps for the shore power

pedestal on the dock, and use an appropriate adapter, if necessary. (a 30 to 20 and 30 to

15 amp adapters are stored in the cord bag in the lazarette. Connect the electrical cord to

the dock power source, matching prongs, twisting, and tightening. Then turn the dock

power source ON.

4. Return to the boat and turn the AC SHORE POWER circuit breaker to the ON position.

5. Verify that you have power to the main electrical distribution panel by looking at the AC

voltage gauge on the SHORE POWER OR GENERATOR distribution panel.

6. All AC circuit breakers should be ON.

NOTE: 30-amp power may not be sufficient to run all the ships systems if the batteries are not

fully charged when connecting to shore power. . The inverter/charger will draw a large amperage

to charge up the batteries and may cause the dock power to disconnect. You may not be aware of

the disconnect because the boats dc system (lights etc) will still be on and the batteries will be

discharging. To prevent this condition, check the AC panel voltmeter at the office station at least

5 to 10 min. after shore power is applied. See if the meter shows that 110/120 volts are available.

If the AC voltmeter is not illuminated, then you have lost AC power. To regain power and

download the AC system, turn off the water heater, and any electric heaters. Check the inverter

control panel at the office station and using the power share button, select a battery charge rate of

15 or 5 amps. This will allow more power to be diverted to ship systems like hot water or electric

heaters. Turn off the Shore Power breaker and go to the dockside power box and reset the

dockside breaker. You may also try another outlet in case you have a weak breaker with the first

outlet. Return to the boat and restore AC power with the Shore Power breaker. This procedure

will be even more important if you are limited to 20 or 15 amp dockside power, which is common

at smaller marinas in Canada. Remember to recheck that AC power is still connected after 10

minutes, if not reduce the load more. The most important thing is to keep the batteries charged.

As the charge level comes up the inverter/charger will draw less power and enable you to turn on

other systems like the water heater and / or electric heaters. The bottom line is if at any time you

need more AC power than is available you can start the generator, which at 11.5 KW can operate

all ships systems and recharge the batteries simultaneously. (See generator operation).

SAFETY NOTE: Any time you are connected to shore power be sure to deselect the inverter

(green LED light “not illuminated”) on the xantrex control panel. Failure to do so could rapidly

discharge the batteries, as the inverter will attempt to run the entire electrical load including

heaters if shore power should fail. For the same reason ensure all electric heaters are unplugged

before disconnecting from shore power. If you need heat, start the furnace!
