Trim angle settings and boat handling
When  the boat  is on  plane,  a bow-up  atti-
tude  results  in  less  drag,  greater  stability
and  efficiency.  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 tendency to steer to one side
or  the  other.  Compensate  for  this  as you
steer. The  trim tab  can also be  adjusted to
help offset this effect.

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.
Bow Down
When the bow of the  boat is down, it is eas-
ier to  accelerate from  a standing  start onto
plane. Too  much trim-in  causes the  boat to
plow”  through  the   water,  decreasing  fuel
economy  and  making  it   hard  to  increase
speed.  Operating  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 operation difficult and dangerous.
NOTE:
@
Depending on the type of boat, the outboard
motor trim angle may have little effect on the
trim of the boat when operating.
