Adjusting boat trim
When the boat is on plane, a bow-up attitude
results in less drag, greater stability and effi-
ciency. This is generally when the keel line of
the boat is up about 3 to 5 degrees. With the
bow up, the boat may have a greater tenden-
cy to steer to one side or the other. Compen-
sate for  this as you  steer. The trim  tab can
also  be adjusted  to  help  offset this  effect.
When the bow of the boat is down, it is easier
to  accelerate   from  a  standing  start   onto
plane.

Bow Up
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.
