I can't figure out why the motor is overheating. I changed theromstat,impeller had out drive gone through. The boat will run fine for about 3 minutes and the temp will spike to 180+. I flushed all the lines to look for impeller pieces. Very few pieces of the impeller were found. This boat has never been in salt water.The motor only has 225 hours on it. When the outdrive was taken apart there was alot of sand in the bottom half of the outdrive. Does any know or think there could be sand in the block?
Any suggestions would help.
