The power trim system is filled at the manufacturer and is
ready for use.
Trim outboard through entire trailering range several times
to remove any air from the system.
The trim system is pressurized and is not externally vented.
The outboard can be raised or lowered manually by loos-
ening the manual release valve 2 to 3 turns counterclock-
wise.
The trim “out” angle of this outboard is not adjustable. The
trim system has an internal valve which will automatically
stop the outward trim travel at 20° when engine RPM is ap-
proximately 2000 RPM or higher; outboard also has to be
in water and in gear.
The outboard can be operated beyond the 20° trim limit for
operating outboard in shallow water if engine RPM is kept
below approximately 2000 RPM.
