Break In Procedure for 4-Stroke Outboards-All Horse Power
Your new engine requires a period of 10 hours break in so that mating surfaces of moving parts wear in evenly. Operate the engine in the water (in gear with a propeller installed) for 10 hours as follows. When breaking in the engine, avoid extended idling, rough water and crowded areas.
3rd to 10th Hour
After 10th Hour
20 Engine Hours
Operate at any speed
No throttle restrictions
Change engine oil
Up to but not exceeding 2000 RPM
Avoid idling for extended periods of time.
Only enough speed to
get the boat on plane and then only enough to keep boat on plane.
Avoid full throttle.
Avoid full throttle for more than 5 minutes at a time.
Operate engine normally.
Subsequent oil changes annually or every 100 hours.
Change engine oil after the first 20 hours of operation. After break in, change engine oil every year or every 100 engine hours.
Use the manufacturer’s brand 4 cycle oil only.
WDI recommends using a fuel stabilizer such as Evinrude 2+4 fuel conditioner every time you fuel up.
Bad gas is the cause of some of the most expensive repairs we see in our service shop. SeaFoam is a good cleaner but it is not a fuel stabilizer and it will NOT make fuel last longer.
Enjoy your new engine. An engine being used is a happy engine. Engines that go unused for long periods of time tend to have more problems.
WDI thanks you for your business. Happy boating!
