Proper operation during this 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. Be sure to follow the engine break-in procedures described below.
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.
Running at high speed without sufficient warm-up may cause severe engine damage such as piston seizure. Always allow sufficient idling time (5 minutes) for the engine to warm-up before running at high speed.
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 three quarter throttle. Avoid running the engine at full throttle.Remaining 7 hours:
Safe boating conditions permitting, operate the engine in gear at 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.
Running continuously at full throttle for more than 5 minutes at a time during the last 7 hours of break-in operation may cause severe engine damage such as seizure. During the last 7 hours of break-in operation, do not operate at wide open throttle for more than 5 minutes at a time.
