I posted here back last year in August and had several replies. Life got in the way and I've just now got back to working on this motor again. It runs fine in neutral at idle but starts to run hot when under a load. I bought the parts to change the thermostat and finished that today. The old thermostat came out in 4 pieces and there was sand wedged behind the cover plate gasket. I cleaned everything up and ran some weedeater line where I could and put everything back together.
I filled up my 40 gallon water barrel put the motor in and fired it up. The tell tale water ran about 80 degrees and a 2 foot strong 1/4" stream of water was coming out of the tell tale at the block.
Put it in gear and the tell tale water shot up to 125 degrees. Back in Neutral water temp drops back to 80 degrees.
I'm at a loss, It seems to be running hotter with a new thermostat, of course there was no thermostat with the condition the old one was in.
