Prop Size, RPMs, & overheating

[jongolds]

I'm not too worried about damage except for from the first time it happened. Since then I've bene wathcing the temp guage closely and you can watch it rise till the revs are limited and then see the temps fall right away as the revs fall.

That's why I didn't think it was the pump at first. The pisser puts out a very strong stream and it cools down very quickly as the RPMS are dropped. If the pump was the problem it shouldn't cool right? I don't know but the pump is the last thing I can thing to try unless it's just the temp sender. But, I would think it's a seperate sender for the guage and the computer anyway so that shouldn't be it anyway (unless I'm wrong again).

That article is great. I printed it out to use for next time but I've already lined up a mechanic that will come to the house to take care of things once I get the boat out of the water this weekend. I wanted to get on this guys customer list anyway so this works out well in the long run.

For anyone else changing poppet valves after talking to the mechanic, he said I should have used a very tiny amount of sealant even with the cork gaskets and you don't need to torque the cover down too much. I of course kept tightening trying until the gasket bulged out the sides while trying to get rid of the leak. Also, regarding the thermostats, sealant is your choice. I think the sloppy application of too sealant much caused a small leak in my old stats that corroded the spark plugs as it ran down the cylinder heads. On the other hand, on my replacements, I didn't use any sealant and I had to redo one of them to add a little sealant to close up another small leak.

So, that's where I stand at this point. I'll keep you posted and thanks again for all the advice.
