BREAK-IN
Proper operation during the break-in period will help ensure maximum life and performance from your engine. The following guidelines will explain proper break-in procedures.
Failure to follow the break-in procedures described below can result in severe engine damage.
Break-in period: 10 hours
Break-in procedure
- For the initial 2 hours:
Allow sufficient idling time (about 5 minutes) for the engine to warm up after cold engine starting.
High speed without sufficient warm-up may cause severe engine damage such as piston seizure.
After warming up, run the engine at idling speed or the lowest in-gear speed for about 15 minutes.
During the remaining 1 hour and 45 minutes, if safe boating conditions permit, operate the engine in gear at less than 1/2 (half) throttle (3000 r/min.).
You may throttle up beyond the recommended operating range to plane your boat, then immediately reduce the throttle to the recommended operating range.
- For the next 1 hour:
Safe boating conditions permitting, operate the engine in gear at 4000 r/min. or at threequarter throttle. Avoid running the engine at full throttle.
- Remaining 7 hours:
Safe boating conditions permitting, operate the engine in gear at the desired engine speed.
You may occasionally use full throttle; however do not operate the engine continuously at full throttle for more than 5 minutes at any time.
For the remaining 7 hours of break-in operation, you may use full throttle; however do not operate the engine continuously at full throttle for more than 5 minutes at a time or severe engine damage such as seizure may result.
