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
