2000 johnson 25 j25tessd overheating and SLOW at WOT

[Kloctower]

Before Trying to remove water tube, put the power head back together and back flush in the tstat housing and out the water tube with the lower off. You can use a stiff piece of wire up the tube to dislodge any zebra muscles or whatever that started to grow there. Catch the water coming out of the tube in a bucket if you don't believe me. It's all in a typical days work at the shop, very common.

Its just so much easier to do it this way.

I'm working toward that now. I am going to do exactly as you have said. Questions though, my power head gasket kit came with two of the same exhaust cover gaskets in the kit. The part list says "one required per assembly" for that part number. Why did the kit come with two? I have the other gasket that goes between the cover and the inner cover just curious why they sent two of the inner cover gaskets. It's the one that is against the block. Is it common for people to remove this one thus needing a second ? Thanks guys. Hope to have it together today. Oh one last thing. On these exhaust cover gaskets do they get the gasket sealant compound?

sorry, hunting season. Many gasket kits come with extra's for some reason. Possible different models require more or less, or maybe someone can't count. Hope it all works out well for you.

Well I cannot get the Youtube upload to play so I'm not going to post the link because the video won't work. But the motor is running great The Tell-Tale is actually warm now instead of staying cold even when the motor overheated before. I am having a small cough from time to time I've been playing with the carburetor and it went away for the most part but still does that once in a while. But I have a temp gun and it the head never gets over 140 everything is working great I ran it for 45 minutes and it is fine. Before it would have overheated and 10 minutes easily
