... SETTINGADJUSTING SCREW FOR MAXIMUM PITCH

1.Unscrewnut(3)oneturn.

2.Insertpin in headof adjustingscrewand

engineisrunningatmaximumspeed.

3.Set position of adjusting screw so that

maximumpropellerpitch correspondsto

theoptimumvalueof fu11speedrpm from

the point of view of vibration and boat

speed.This enginespeedwill dependon Fig.9

theboat'ssizeandhuIl form. It win nor-

mally he in the regionof 200) rpm and

mustnotexceed2250.

Notethat the propulsivepowerof theengine(propellertorque)is nearlyconstant

for enginespeedsin therange1800-2(XX)rpm but falls at higherenginespeeds.

Thismeansthat,withacontrollablepitchpropeller,maximumpropulsivepowerwill

mostboats,ofrunningtheengineat themaximumof 2250rpm. Onlyif theboatis
