Setting Trim Angle While Running Engine at Idle
Speed
The exhaust relief hole on the outboard may become submerged
if the outboard is trimmed full‑in while running at idle speed. This
will cause exhaust restriction, rough idle, excessive smoke, and
fouled spark plugs. If this condition exists, trim the outboard up
until the exhaust relief hole is out of the water. The outboard
should be lowered for accelerating from a standing start or from
idle speed.
Engine Break‑In Procedure
IMPORTANT: Failure to follow the engine break‑in procedures
can result in poor performance throughout the life of the engine
and can cause engine damage. Always follow break‑in
procedures.
GASOLINE/OIL BREAK-IN MIXTURE
NOTE: Do not use premixed gas and oil during break‑in. Use
straight gasoline during engine break‑in and after engine
break‑in.
The engine break‑in procedure for an OptiMax outboard is
important to ensure proper performance and maximum life from
the engine. The following break‑in procedure allows the internal
engine parts to wear‑in evenly. Incorrect engine break‑in can
shorten the engine life.
