We seriously considered chucking the thermostat, but then I read it can cause serious damage to an outboard to run at the wrong temperature. Since we could get the old one working, we decided to keep it. If we were going to buy a new one, I found the original Yamaha parts available at www.boats.net. Or, you can get a Sierra version of this thermostat (part # 18-3623) available at a variety of places. I could never figure out if the Sierra kit that includes a seal means it includes the head cover gasket, or if it means the plastic grommet that surrounds the thermostat. more

Picked up the impeller kit yesterday and found your instructions THANKS! Re-assembled everything and cranked her up about an hour ago. I know it takes a short bit of time for the thermostat to kick in but still no squirt. Found your other post about the thermostat and took the cover off, did a double take…. there is not even a thermostat on this motor! Empty hole.. Whoever worked on this motor last must have had some mighty good scotch or maybe even some moonshine as I noticed the old gasket at the impeller housing was on the wrong side of the plate as well.

What we found was a lot of sand and gunk, and a corroded thermostat. We pulled out the thermostat for cleaning. The head cover plate was seriously pitted on the interior face due to saltwater corrosion. The corrosion protection installed by the manufacturer is gone over much of the interior. We didn’t do anything about this, except clean off the deposits.

Re: Take out thermostat on Tohatsu 8hp 2 stroke?

Thanks everyone. I'm going to clean out the motor and put the thermostat back in. I cleaned it up and tested it in heated water, it opened. I then put it in cold water and it closed. Repeat repeat repeat, it looks good to go back in. <br /><br />Aside from Salt Away is there a homemade formula for actively removing salt crystals in the block?<br /><br />Thanks again. more

Salt away works well. Vinegar will work, but you need a 50% solution and it's best to run the engine it, stop and wait 30 minutes and then run it again. Think of vinegar as a field expedient that will work, rather than as a dedicated product that will work really well. here

I just checked the spark plugs and found out the wrong ones were being used . I'm going to get the correct ones, I hope the motor will run cooler. I will post the results.
