Operation
55
Bow Down
Too much trim-in causes the boat to “plow”
through the water, decreasing fuel economy
and making it hard to increase speed. Oper-
ating 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.
TIP:
Depending on the type of boat, the outboard
motor trim angle may have little effect on the
trim of the boat when operating.
EMU27934
Tilting up and down
If the engine will be stopped for some time or
if the boat is moored in shallows, the out-
board motor should be tilted up to protect the
propeller and lower casing from damage by
collision with obstructions, and also to re-
duce salt corrosion.
WARNING
EWM00221
Be sure all people are clear of the out-
board motor when tilting up and down,
Body parts can be crushed between the
motor and the clamp bracket when the
motor is trimmed or tilted.
WARNING
EWM00250
Leaking fuel is a fire hazard. If there is a
fuel joint on the outboard motor, discon-
nect the fuel line or close the fuel cock if
the engine will be tilted for more than a
few minutes. Otherwise fuel may leak.
NOTICE
ECM00241
●
Before tilting the outboard motor, stop
the engine by following the procedure
on page 51. Never tilt the outboard mo-
tor while the engine is running. Severe
damage from overheating can result.
●
Do not tilt up the engine by pushing the
tiller handle (if equipped) because this
could break the handle.
