ENGINE INSTALLATION
Determining the Mounting Height of the Outboard
The following outboard mounting height settings will work good for
most applications, however, because of different boat/hull designs,
the setting should be rechecked by test running the boat. Refer to
Water Testing.
•
Installing the outboard too high on the transom will allow the
water intake to suck in air and cause cavitation. Cavitation
causes the engine to overspeed in spurts and reduce thrust.
This condition should be avoided by proper height setting.
•
Installing the outboard too low on the transom will allow
excessive drag.
BOATS WITH A "V" BOTTOM HULL
1. Measure the width of the leading edge on the water intake
housing. Make a horizontal line on the transom up from the
"V" bottom the same length as the width of the water intake
housing.

2. Place (center) the outboard on the boat transom. Set the
height of the outboard on the boat transom so that the front
edge of the water intake housing is in line with the horizontal
line made in step 1. Fasten the outboard to the transom at this
height.
