10. With the shift handle in forward and the reverse gate in forward, with the cam roller at the end of the slot, adjust
the cable and/or cable anchor position to this condition. Shift to reverse and back to forward. The roller should
be at the end of the cam slot such that the gate cannot be forcibly rotated toward reverse. Pull on the gate by
hand to verify this.
If this forward lock condition is not met, readjust the cable positions.
11. When converting to jet drive, your motor will have to be raised to the height shown in the diagram pg. 3, using
a straight edge under the boat. Test run the boat and then raise or lower the motor 5/16 inch at a time to obtain
best results.
The motor has three sets of upper mounting holes. You will use one set to begin with. Mark pencil lines on the
boat transom through the other sets. Then if you wish to go up or down 5/16 inch, you can drill one alternate set
of holes 5/16 inch up or down from the pencil marks. By alternating between these two sets of transom holes
and the three sets of motor holes, the motor can be moved in 5/16 inch increments over almost one inch. The
transom height should e about 26 inches measured vertically from the boat bottom.
If you raise it too much it will suck air and cavitate, either on start up or when banking on turns. When
cavitating, the motor overspeeds in spurts and shakes considerably in the motor mount. This is not a normal
condition and should be avoided by proper adjustment of motor height on each individual boat. If you lower it
too much you will have excessive drag, therefore mount the motor as high as possible without allowing
cavitation.
SETTING MOTOR HEIGHT
CAUTION
When starting the engine for the first time, watch to see that the cooling water comes out of the small hole
at the rear side of the engine just below the power head. This is to check your assembly of the cooling
water pump and its connections
