Water testing
Checking for Cavitation (Continued)
2. Rough Water Plate (b) – Using this type of plate
may be helpful in reducing cavitation when running
in windy rough water conditions where air is
sucked-in the water intake when jumping waves.
Install a 1/32 in. metal plate that extends from the
hull bottom to the top of the water intake housing.
This plate tends to reduce air intake as well as re-
duce spray.

Shift Cable Installation
WARNING
The shift cable must be adjusted to lock the re-
verse gate against unexpected engagement
(caused by water pressure hitting the gate) while
operating the boat in forward. Activation of the re-
verse gate will cause sudden unexpected stopping
of the boat. Sudden stopping may cause occu-
pants to be thrown within the boat or even out of
the boat. This action may result in serious injury or
death.
1. Attach shift cable (a) to the shift cam (b) with flat
washer and locknut as shown. Tighten locknut
against the flat washer, then back-off the locknut
1/4 turn.
2. Place remote control handle into full forward posi-
tion.
3. Adjust the brass barrel (c) on the shift cable so that
roller (d) is at the full end of travel (bottom) in the
shift cam when the remote control is in full forward.
4. Attach the brass barrel (c) to the bracket with bolt
and locknut. Tighten the bolt until it seats against
the barrel, then back-off the bolt 1/4 turn. Hold bolt
from turning, and tighten locknut on bolt. The barrel
must be free to pivot.

5. Recheck the shift cable adjustment in forward shift
position. The correct shift adjustment will position
the cam far enough on the roller in order to lock the
the reverse gate into forward position. You should
not be able to forcibly push up the reverse gate to-
ward neutral. Pull on the reverse gate by hand to
verify this.
IMPORTANT: The forward locking of the reverse
gate must be met. If not, readjust the shift cable.
