Outboard Motor Mounting - Yamaha F225F Service Manual

Outboard motor mounting

Proper mounting of the outboard motor pro-
vides better performance, maximum reliabil-
ity, and the highest customer satisfaction.
This chapter contains the specifications nec-
essary to mount the outboard motor, and may
vary slightly depending on applications.
When mounting the outboard motor, make
sure that there is sufficient clearance for the
outboard motor to fully tilt up, and to fully
move to port and starboard. See "Dimension"
(3-2).
1. For single outboard motor installation,
place the outboard motor on the vertical
centerline of the boat transom.

the boat transom are equal on both sides.

the outboard motor is aligned with the C/L of
the boat transom. Place the other two out-
board motors on both sides so that the dis-
tance from the C/L of each outboard motor to
the C/L of the boat transom are equal.
