2005 Yamaha Outboard F25D T25D Boat Owners Manual

Operation
Bow Up
NOTE:
Too much trim-out  puts the bow of the  boat
too high in the water. Performance and econ-
omy are  decreased because the  hull of the
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.
Depending on the type of boat, the outboard
motor trim angle may have little effect on the
trim of the boat when operating.
EMU27933
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.
