TRANSOM HEIGHT
The anticavitation plate of the
outboard motor should be
0 − 50 mm (0 − 2 in) below the
bottom of the boat.
The correct dimensions differ
according to the type of the boats
and the configuration of the
bottom of the boats. Follow the
manufacture's recommended
installation height.
The water level must be at least
100 mm (4 in) above the
anticavitation plate, otherwise
the water pump may not receive
sufficient cooling water, and the
engine will overheat.
When the outboard motor is
installed extremely low, the idle
port may be immersed and the
engine may become hard to start
or may run poorly. Check that
the idle port is high enough from
the water level when the engine
is stopped with the boat fully
loaded.
