Drive Trim Angle - Monterey 180 Edge Owner's Manual

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 stand still; 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.
