Adjustments65 CommSteering Friction
r:jl Adjust steering friction with motor mounted to boat by simply
loosening or tightening handle provided Steering friction should be adjusted so that slight drag is felt when turning This will allow smooth steering'" Steering friction adjustment should not be overtightened to allow for "hands off" steering which could result in loss of control Motor Angle
f21 The stern bracket has five positions for adjusting the motor to
allow for transom angle and boat loadingThe vertical angle of motor on boat must be adjusted for best performanceMotor should be perpendicular to water when boat is underwayThis adjustment can only be determined by observing boat at operating speedSet angle adjustment for your usual loadAngle adjustment should be changed if boat loading results in improper motor anglePlaning type hull should ride with bow slightly out of water at full throttle'" If engine is tilted forward so as to cause plowing, swamping may occur in rough waterIf engine is tilted aft so as to cause porpoising, steering may be erratic or unstable
