Operation

There are 5 holes provided in the clamp

bracket to adjust the outboard motor trim an-

gle.

1. Stop the engine.

2. Tilt the outboard motor up, and then re-

move the trim rod from the clamp bracket.

3. 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”).

IP:

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.

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.

Bow Up

Too much trim-out puts the bow of the boat

too high in the water. Excessive trim-out can

also cause the propeller to ventilate, which re-

duces performance further, and the boat may

“porpoise” (hop in the water), which could

throw the operator and passengers over-

board.

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.
