I assume your question is about the engine and transmission.
Breaking in the engine and transmission and cutless is not specific to any boat make - and is no different than a new vehicle.
This is my way over the first ten hours
Run it frequently. Run the engine at various power levels for the first two hours - changing from a slow cruise for 10 - 15 minutes or so, 3 to 5 minutes of wide open throttle, then maybe ten minutes of medium cruise, etc.
You get the picture. Let the moving parts do the initial couple of hours of wearing in against each other (called break in) at various speed and power levels. Just change the throttle setting every 10 to 15 minutes for the first couple of hours. Then for the rest of the initial ten hours remember to vary your RPMs every 20 minutes or so and limit full throttle to short runs of less than ten minutes.
After ten hours - which roughly equates to the first 500 miles of 'break in' called for by your auto maker - change the engine oil/filter and you are good to go. Enjoy.
In my case I have a tendency to drift along at 6 knots 99% of the time (which is barely above an idle) and I have to remind myself to open the throttle for a few minutes to clean out the carbon and exercise the turbo. Diesels do best when run under enough load to keep them hot.
There is also a break in period for the engine mounts. The rubber in the mounts will compress a bit. Somewhere along about 50 to 100 hours your manual will call for having the alignment checked. This is an excellent idea. And you can check it yourself. I will not go into my usual tendency to describe it in detail. You can find instructions with pictures on the internet.
cheers, eh wot :mrgreen:
