Bummer!

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.
