Re: GP760 WAveRunner
I had 2 GP760's bought new. I highly modded each one. They are extremely easy to work on. I dare say you could rebuild it yourself with little problem. The 760's were 2 stroke so I'm not sure what you mean by "oil all over the bottom". The oil is stored in a separate tank and gets mixed in the carbs. Perhaps you have a leak in the tank or the oil lines leading to the carbs. At any rate, if the engine did not get the proper amount of oil, it would blow. I removed the oil tanks in mine and ran with pre-mix gas. I am sure you could rebuild this engine for a whole lot less than the cost of a complete engine. Try going to greenhulk.net and search there. It's a jet ski forum filled with a bunch of jet ski fanatics. Lots of knowledgeable people who will offer very good advice.
