Yea, the top end is a split case that comes with the one seal and valves installed. It was $35 and the rings $41. I haven't broken the older engine apart and didn't realize the cam was plastic. If I had, I think I would've gone a different route. I've also been playing around with the idea going electric...24 volt. I don't travel great distances so longevity wouldn't be too much of a problem.

I would check the cam in the old one, if it failed then that would explain the loss of compression. Running hot and cooling down isn't going to cause a loss of compression via the rings typically, unless you ran it out of oil. How did you come to the conclusion it overheated?

A local small engine repair shop. The engine ran fine and I turned it off when I beached it on the shore of the river. The next morning it wouldn't start so I figured it made sense to me. It did seem to have less power before I shut it down.

Was the air plenum intake, and the hood in place when you were running it? Something would have to be seriously wrong for the engine to overheat to the point of fatal damage. The stock setup left much to be desired, but it wasn't that bad. Those engines ran hotter than they should have, and time may have just taken it's toll on yours, but it was a culmination of trips not just that last one.

I agree. I'll let you know what I find when I take it apart.

Is it possible you ran over a weed bed or gravel and clogged your grate while heading to the beach?

No, the grate was never blocked as the water was plenty deep enough and there aren't any weeds.

@Painlesstom the problem with the compression on my engine was due to the valve guide moving down and holding the valve slightly open.

That makes sense, overheating caused the guide to loosen. Now that you mention it, I've heard of that happening on these before. New block is the only real fix, so you should be good with the parts you got. Thanks for the update.  \./8
