Not without a rebuild or two along the way.


Is in common for a maintained diesel to last 5000 hrs before needing a
rebuild.


Generally speaking, the lower the HP rating of the engine, the longer
it will last. In your case, they have that engine rated all the way up
to, I beleave, over 400 HP. On that engine, at only 210 HP, I would
say that 10,000 hours is not out of the question, maybe even higher.
The engine is just not being pushed very hard, so it should last a
very long time, provided it's proped correctly.

What kind of boat do you have it in? Beware, if your dealing with a
displacement hull, adding a lot more HP usually does not result in a
significant increase in speed unless it gets up on plane and has a
very small keel, so it doesn't keel walk, which can be scary.
