trim angle.
The trim angle of the outboard motor helps
determine the position of the bow of the boat
in the water. Correct trim angle will help im-

reducing strain on the engine. Correct trim

boat, engine, and propeller. Correct trim is
also affected by variables such as the load in
the boat, sea conditions, and running speed.
