Mounting The Outboard Motor - Yamaha F50D Servise Manual

Mounting the outboard motor

Proper mounting of the outboard motor will
mean better performance, maximum reliabil-
ity, and maximum customer satisfaction. This
chapter contains the specifications neces-
sary for the outboard motor mounting, and
may vary slightly depending on application.
When mounting the outboard motor, also
make sure the outboard motor has the clear-
ance to provide full movement, from both
PORT to STBD, as well as during trim and tilt
functions. See "Dimensions" (3-2).
1. Set the outboard motor on the vertical
centerline of the boat transom.
