Such a nice day in Oregon. Decided to try getting the boat out for the first time this year. Fired her up in the driveway and ran her for at least 15 minutes. Everything looked great. Took her down to the lake and put her in. Fired her up and the temp gauge continued to go up towards 240! Not sure what happened between the house and the lake. I have ordered a new thermostat. I'll check the impeller next and just hope that it's not the water pump. i had drained all of the water out for the winter and the boat is in the work shop for the winter. Will let you all know what I find. Any other ideas? Thanks - Peter

You did take the muffs off before the trip to the lake didn't you?
Seen that happen a few times.

Are you sure it really got that hot. The reason I ask is that put on the flush muffs and fired up my 20' Formula I am trying to sell after it had a 3 plus year nap. All seemed fine but the temperature gauge almost immediately pegged out on hot so I shut it down and thought great, I need to replace the impeller. This was even though water seemed to be coming out of the exhaust ports. A couple hours later a friend came by and he talked me into firing it up again. I turned the key and the temperature gauge was still pegged out on hot. Hmmm. So, I started the engine and we monitored the temperature by putting our hands on the risers and manifolds and it was running cool as a cucumber and stayed that way for 15 minutes or more. So, maybe I have a bad temperature gauge, and maybe you do, too.

Yes I took the muffs off, although I'm not beyond making that kind of mistake. I'm also sure that the engine got that hot, cause I could smell oil cooking and could not touch the engine at all. New thermostat today and we'll see. I will have this fixed soon!

Well, looks like I will have to pull the lower unit to check the impeller and I think i will pull the water pump while I'm at it just to make sure. Any other suggestions? I put i a 140 degree thermostat and the temp went up to 180 and was still going when i shut down.

You're going the route I'd take.
First the t-stat and then the impeller.
But me being an outboard guy it would be reversed.

Did have an interesting problem one time with Guinea Wasps building a nest in the foot preventing the water uptake.
