Checking Power Trim Fluid
The power trim system is filled at the manufacturer
and is ready for use.
Trim outboard through entire trailing 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
loosening the manual release valve 3 to 4 turns.
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 approximately 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.
