DJUSTMENTS
By changing the outboard motor’s drive angle, the vessel’s bow can be made to rise or fall. The
performance and stability of a vessel depends a great deal on correctly trimming the motor. The correct
trim angle depends on the vessel’s handling characteristics, the sea and loading conditions. Care must
therefore be taken to ensure the outboard is trimmed correctly under different sea and loading
conditions.
Proper Trim Angle
. The trim angle is optimum when the craft is parallel
to the water surface while running. Physically lift the motor, remove
the thrust rod from series of holes in the stern bracket and re-adjust it
higher or lower. Either alters the angle thrust from the propeller is
delivered, relative to the water surface and the craft, and the attitude
(or trim,) of the craft to the water accordingly.
Trimming Out Excessively
(bow rises too high) If the trim angle is set to
far out, the bow will rise out of the water and the speed will decrease.
Furthermore, the bow may sway or the bottom may slam the water
while cruising. In this case decrease the trim angle by setting the thrust
rod in a lower hole.
Trimming In Excessively
(bow sinks or broaches) If the trim angle is set
too far in, the bow will sink or plunge into the water decreasing speed
and swamping your craft. Moreover, as the bow buries into a wave, the
resistance created when hitting the wave causes the bow to dig into
the water and the craft to veer sharply off course. Craft control is lost,
passengers are thrown around, and this can even result in capsizing. In
this case increase the trim angle by setting the thrust rod in a higher
hole.
In general, the Raider 40 HP trim should be set to the second hole from the bottom. However, this does
not preclude the Operator from assessing load and prevailing sea conditions and adjusting the Trim
setting accordingly.
