I have 2 ox66 200hp engines. They run well and have few problems. Admittedly, I don't run them real hard for long periods of time but at least once a day I open them up to 5500rpms and "let them eat!" They are getting on down the road a bit in age and parts are sometimes needed to be ordered, but otherwise, I have about 800 hours on one and about 350 on a rebuild on the other. I like them so much I recently had a chance to upgrade to 2009 250 4 strokes for about 20K and passed because I could not justify the expense based on current engine performance. You will love it!
