Too much trim-out puts the bow of the boat

Change the position of the trim rod in di-
rection “A” to raise the bow (“trim-out”).
Change the position of the trim rod in di-
rection“B” to lower the bow (“trim-in”).
TIP:
The outboard motor trim angle changes ap-
proximately 4 degrees when the trim rod posi-
tion is changed by 1 hole.
4.
Make test runs with the outboard motor
set at different trim angles to find the po-
sition that works best for your boat and
operating conditions.
Bow Down
Too much trim-in causes the boat to “plow”
through the water, decreasing fuel economy
and making it hard to increase speed. Resis-
tance at the bow is greatly increased, height-
ening the danger of “bow steering” and
making operation difficult and dangerous.

Adjusting boat trim
Generally, a boat is stable when the keel line
of the boat is up about 3 to 5 degrees. With
the bow up, the boat may have a greater ten-
dency to steer to one side or the other. If this
occurs, adjust the trim angle.
