I know a guy that had a 28 Magic cat bought in 2001 with a 500EFI in it.
He put over 800 hours on it without a problem, took the engine out and sold
it to another guy with a 30 Eliminator Eagle. Still in the boat and that boat
has 2 1/2 seasons on it too. I also know several guys with 400 plus hours
on their 525's without problems. I know a guy with a whippled HP500EFI with
over 500 hours on it with no problems.
I believe that it has to do with how you maintain it and how you drive it.

Is there a trend that you've seen that these engines follow? Synthetic oil, or regular maintnance following the Merc schedule, etc.? You say "how they drive it". Not running at max RPM, running at no more than 80% of max, no skiers, etc.?
