Buy running the HD100 I think you can rule out that your failure was due to an oil related problem. Unless the oil pump itself went out.

Virtually all mechanical items will fail at one time or another. Yes 200 hours is low and I would not have bet you would have any problems at all if the engine was taken care of as you say. But there are faulty internal parts which I am sure make their way into our engines. maybe that was your case or maybe it was the EMM as someone suggested.

As a owner of a 2002 225 HO I am certainly sorry for your problem. Mine is approaching 150 hours with no core engine issues.

My frustration is that there is no warning system built into these engines to warn owners when an injector goes bad and ends in a blown power head. These engines are designed and tuned right on the edge, so its no wonder that we have a percentage that have problems in all brands. (Evin, Merc, Etc) That being said, there are a very high percentage of engines out there with more years and hours still running strong. I will admit that the numbers of good running engines does not make you feel any better when a failure happens to you.

Sometimes I wish I had my 1985 150 XP Back. One hell of a motor!! Not sure if they would last long in todays world with Pee for gasoline. And that aspect of things is only going to get worse.
