One thing to consider on a ski boat is we basically run the engine near 3700 RPMs all the time. Much more abusive than how we drive cars. My Malibu is 10 years old and I change every 50 hours. I wish the old oil was coming out clean, but it is not. Maybe I should try synthetic.

If you are concerned with the oil, call Inmar directly. They have customer support (real people) for us boat owners who can tell you exactly what will be best to use based on what you are able to buy where you live. I have called them for support on fixing my motor for the last 3 years and they have given incredible service. Go to inmar.com or just call them direct at 901-353-9930.

akale15 - the ski that Toddl has posted above is in way better shape than mine and it priced right. Looks like a good find.

I am looking for a new ski and would sell my 65.5 Custom X5. Timing might not work for you as I do not know how quick I will end up with a new ski, but will check back with you when I am ready to sell it.
