details.
MC tried putting this in the manual but must have given up because it was almost impossible to get people to bring their boats in for the 25 and 50 hour service intervals. Then, they would complain when something would go wrong when it would surely have been prevented by them coming in for service.

My advice- RTFM and follow the instructions. If I was building something like this and selling engines that needed break-in, I would probably be less forgiving when they didn't come in when specified, but some allowance needs to be made for the fact that some people are out of the US and some of those who are here are many hours away from a dealer.

This is why I buy used. Engine break-in means nothing to me.


Follow it best you can. It's tough to stay outta the throttle. Lol

New Boat Break-in

The first 50 hours of operation are the most important for establishing acceptable wear parameters for the boat. Proper break-in will ensure maximum performance and the longest possible powertrain life. The break-in period allows moving parts within the engine and transmission to wear in properly. All Mastercraft boats are lake tested on the water before leaving the factory but the break-in period must continue for the first 50 hours of your ownership.

I think it is clear from above that the break in period is 50 hours.

Then, one of the bullets on that page states:
Vary the engine speed. Never run the engine for more than three minutes at any constant rpm during the break in. Follow the specific instruction will assist in the proper breaking of rings and bearings


JJ. Illmor clearly reads do not exceed 3000 rpm in the first hours then do not exceed 5200 ever. Semantics is confusing this situation with two owners manuals. Stick to the illmor manual and you'll be fine.

The first hour do not exceed 3000rpm...

Is this even possible to properly break in the engine?
I won't say exactly who told me this....BUT

I went on a tour of the Ilmor factory in Plymouth, Michigan and I asked someone very high up this exact question.

His response?

Be careful the first hour then "balls to the wall" my friend. He knew I ordered the 7.4 and yes he said "balls to the wall"

That makes sense according to the ilmor manual

Hour is probably more than enough, 10 is the absolute longest I could wait. Was probably closer to 8.5 hours but I rounded up.

I think it would be a great offering, and I hope MC is listening, that for new boat orders you could order it with the engine broken in. For example, if I could order it with 10 hours on it, conditioned in their factory, with their specifications and technology, I think I would do that.

In the spring when I receive my new X23 I'm going to go bat crap crazy trying to adhere to these engine rules.
