Trim
TRIMMING OUTBOARD “OUT” (“UP”)
WARNING
Excessive trim “out” also may reduce the stability of some high speed hulls. To
correct instability at high speed, reduce the power GRADUALLY and trim the out-
board “in” slightly before resuming high speed operation. (Rapid reduction in
power will cause a sudden change of steering torque and may cause additional
momentary boat instability.)
1. Will lift bow of boat, generally increasing top speed.
2. Transfers steering torque harder to left on single outboard installations below 23 in.
(584mm) transom height.
3. Increases clearance over submerged objects.
4. In excess, can cause porpoising and/or ventilation.
5. If trimmed out beyond the water pickup, reduced water supply can cause overheating
resulting in engine damage.
