DRIVE TRIM ANGLE

Trim angle is the angular relationship between the lower drive unit and the

transom of the boat. Boat trim while underway greatly affects boat

performance and efficiency. For best results, the boat should be on plane

and trimmed to reduce the wetted surface. With less boat in the water,

both speed and fuel economy increases. Engines with manual trim must

be adjusted for best overall operation for the load and conditions. Engines

with power trim should be adjusted continuously for best results.

If the engine is trimmed in too far (closer to the boat bottom), speed drops,

fuel economy decreases, and the boat may not handle correctly. However,

it does provide better acceleration from a standstill; and because it forces

the bow down, visibility is improved. If the engine is trimmed out too far

(away from the boat bottom), steering torque may increase, the boat may

be difficult to get on a plane, and may bounce.
