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
will cause 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.
