Re: New Motor Break In Procedure
this is the break in procedure that came with my motor........
Break-In
Taking care now to break-in your new Indmar engine is VERY important. When broken in properly, your engine will last longer, run better and require fewer repairs over its lifetime. Your new Indmar engine does not require an elaborate break-in procedure, just a little care and common sense for the first few hours.
Break-in Tips
Always let the engine warm up to normal operating temperature before accelerating.
Avoid fast accelerations and don't carry (or pull) a heavy load during this period.
Check the engine oil frequently. During the first 50 to 100 hours, the engine can use more oil than usual. Maintain oil at proper level but do not overfill.
Vary the boat speed during break-in. Do not run at the same RPM for very long.
Observe gauge readings and check for loose mountings, fittings, nuts, bolts and clamps.
Report any abnormal operation, noises or vibrations to your dealer.
Break-in Steps
1. For the first hour, do not exceed 2000 RPM; vary RPM continuously.
2. For the second hour, do not exceed 3000 RPM.
3. For the next 5 hours, do not exceed 4000 RPM.
After the first 10 hours of operation, take your boat tO the dealer for its first engine oil and filter change and engine checkup. Your dealer is best equipped to check the engine immediately after break-in.
After break-in, your engine may be operated at any RPM within the limits for the engine. Your boat must be fitted with a propeller that will allow the engine to turn between 4400 and 4800 RPM at wide-open throttle with a normal load in the boat.
Engine Oil Requirements
Indmar uses and recommends Pennzoil Marine 15W-40 Marine Oil. If Pennzoil is not available, any 15W40 oil meeting the API specifications of SJ/CH4/CG4 is acceptable. If engine is to be used in conditions below 20 degrees F (-7 C) use 10W30 API SJ/CD motor oil.
Synthetic Oil
Synthetic oil that meets our requirements of 15W-40 SJ/CH4/CG4 is acceptable to use after 100 hours of operation with the recommended conventional oil. The use of synthetic oil does not change the requirement of 50 hour oil change intervals.
Should I follow this or just run it and don't goose the throttle under heavy load for a while?
