Tilting Up And Down; Procedure For Tilting Up (Power Trim And Tilt Models) - Yamaha F250B Owner's Manual

Operation
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.
TIP:
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
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 mo-
tor is trimmed or tilted.
