Setting Trim Angle While Running Engine at Idle Speed

The exhaust relief hole on the outboard can become submerged on some
boats if the engine is trimmed full in while running at idle speed. This may result
in exhaust restriction, rough idle, excessive smoke, and fouled spark plugs. If
this condition exists, trim outboard up until exhaust relief hole is out of the
water.

b - Relief hole above waterline (correct)
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.
1. For the first two hours of operation, run the engine at varied throttle
settings up to 4500 RPM or at three‑quarter throttle, and at full throttle for
approximately one minute every ten minutes.
2. For the next eight hours of operation, avoid continuous operation at full
throttle for more than five minutes at a time.

Fuel Supply Module Priming Procedure

The fuel supply module (FSM) is not vented to the ambient air. The air trapped
in the FSM, fuel lines, and fuel rail, will be slightly compressed during the initial
ignition key "ON" with a dry or drained fuel system. Additional key "ON" events
under these conditions, will not compress the air further to finish the priming of
the FSM. Excessive number of key "ON" events may eventually damage the
fuel pumps. The volume of air trapped in the FSM must be purged to prime the
fuel system. This can be achieved by connecting a tool to the fuel rail Schrader
valve fitting to quickly purge the system into an approved container, or by
cranking the engine.
