It's time for a new engine.

But you need to determine the failure before you put a new one in...make sure the oil pump is working, and rebuild the carbs...or you could have ingested water at some point.

Unless you forgot to type a '1' in front of the '30', you might as well start undoing everything and get it out of the boat.

Sorry, but it only takes a second, and yours is shot.

[Technical Support]

It takes someone experienced to look at all your parts to tell what happened. There is a tech article here showing you what to look for on the pistons to see what kind of failure you had, for example. Tear it all down for inspection.

SO WHAT SERVICE BOOK DO YOU SUGGEST? ALSO WHAT COMES IN A TOP END KIT? I KNOW I HAVE TO GET IT OUT ...SEE WHATS WRONG. "HOW BAD"

[Technical Support]

I recommend the OEM Service Manual - and how bad could be a wide range - there's no point in guessing, just tear it down. Send in pics when you get it apart and we can help with the diagnosis.
