boat is pushing the water and there is more
air drag. Excessive trim-out can also cause
the propeller to ventilate, which reduces per-
formance further, and the boat may "por-
poise" (hop in the water), which could throw
the operator and passengers overboard.
1. Bow up
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.
1. Bow down
NOTE:
Depending on the type of boat, the outboard
motor trim angle may have little effect on the
trim of the boat when operating.
EMU27931
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 casing from damage by colli-
sion with obstructions, and also to reduce
salt corrosion.

WARNING
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.

WARNING
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.

CAUTION:
Before tilting the outboard motor, stop
G
the engine by following the procedure
on page 33. 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
G
tiller handle (if equipped) because this
could break the handle.
