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 hour of operation, run the engine at varied throttle
settings up to 3500 RPM or at approximately half throttle.
2. For the second hour of operation, run the engine at varied
throttle settings up to 4500 RPM or at three‑quarter throttle,
and during this period of time, run it at full throttle for
approximately one minute every ten minutes.
3. For the next eight hours of operation, avoid continuous
operation at full throttle for more than five minutes at a time.

the engine without the intake housing in the water.
