Trim Plate Adjustment
The jet drive unit trim plate is factory set for general applications. Should a particular boat experience porpoising problems, the
trim plate can be adjusted as follows:
1. Loosen both jam nuts on the trim plate (one starboard and one port).
a - Trim plate components (one each side)
b - Jam nut
c - Small diameter washer
d - Large diameter washer
e - Plate
f - Screw
2. Turn both screws the exact same number of turns. Tighten both jam nuts against the trim plate. The distance from top of nut
to bottom of boss should be equal on both sides.
!
WARNING
Adjusting the trim plate may affect boat handling, resulting in sensitive steering or reduced turning ability. Boat handling
characteristics also vary with the load distribution in the boat. Use caution after adjusting and check for acceptable handling
characteristics under all loading conditions.
