NOTICE
Operating the engine with the outboard in the tilt range can damage the
engine or the transom. If operating the engine in the tilt range, such as in
shallow water, do not exceed 2000 RPM.
1. Reduce the engine speed below 2000 RPM.
2. Tilt the outboard up. Make sure all the cooling water intake holes stay
submerged at all times.
3. Operate the engine at slow speed only.
Models with a three‑ram trim system: If engine speed exceeds 2000 RPM, the
outboard will automatically return down to the maximum trim range.
Models with a single‑ram trim system: The outboard will remain at the selected
tilt position, regardless of engine RPM.
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.
