Outboard Installation
Selecting Accessories for Your Outboard
Genuine Mercury Precision or Quicksilver Accessories have been specifically designed and tested for your outboard. These
accessories are available from Mercury Marine dealers.
IMPORTANT: Check with your dealer before installing accessories. The misuse of approved accessories or the use of
nonapproved accessories can damage the product.
Some accessories not manufactured or sold by Mercury Marine are not designed to be safely used with your outboard or
outboard operating system. Acquire and read the installation, operation and maintenance manuals for all your selected
accessories.

Determining the Mounting Height of the Outboard Jet
The following outboard mounting height settings will work good for most applications, however, because of different boat/hull
designs, the setting should be checked by test running the boat.
•
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.
