Operation
43
Bow Down
Too much trim-in causes the boat to “plow”
through the water, decreasing fuel economy
and making it hard to increase speed. Operat-
ing with excessive trim-in at higher speeds
also makes the boat unstable. Resistance at
the bow is greatly increased, heightening the
danger of “bow steering” and making opera-
tion difficult and dangerous.
NOTE:
Depending on the type of boat, the outboard
motor trim angle may have little effect on the
trim of the boat when operating.

Tilting up and down
If the engine will be stopped for some time or
if the boat is moored in shallows, the outboard
motor should be tilted up to protect the propel-
ler and lower case from damage by collision
with obstructions, and also to reduce salt cor-
rosion.
WARNING
EWM01540
Be sure all people are clear of the out-
board motor when tilting up and down,
also be careful not to pinch any body parts
between the drive unit and engine bracket.
CAUTION:

●
Before tilting the outboard motor, follow
the procedure under “Stopping engine”
in this chapter. Never tilt the outboard
motor while the engine is running. Se-
vere damage from overheating can re-
sult.
●
To prevent the cooling water passages
from becoming frozen when the ambient
temperature is 5°C or below, tilt the out-
board motor up after it has been
stopped 30 seconds or more.
