On a 1983 johnson 50hp, do I need to take off the cylinder head cover to get access to the thermostat? Or is there an easier way?

Re: thermostat question

you have to take the cover off its simmple.Get new gasket and some sealer. watch when you take cover off has spring and look at the way its in there so you put back right.

Re: thermostat question

I think I'll just change the thermostat and the gasket. I don't see how the poppet could have anything wrong, it is a hard piece of plastic. And the spring, could it really be needing replacement???

Re: thermostat question

how do I test it to see? Also, it has been recommended that I use some gasket sealer when I put the gasket back on, but which kind exactly are we talking about? I went to the parts store and they told me the red rtv silicone was what I needed, but I have done some reading and I have heard about some of the "brown" stuff that I think is made by 3M, anyone have the answer for me? I just want to do this once, so I want the right stuff.

Re: thermostat question

I use the brown gasket sealing compound that you speak of. It has a built in brush on the lid of the can. Go to your local BRP dealer/mechanic, they will have it. DOnt worry about testing the poppet valve, just replace it while you're in there.

Re: thermostat question

does anyone know the name of this stuff? So I can ask the guy behind the parts counter and actually get the right stuff?

Re: thermostat question

My can is an actual BRP product. It is blue, and titled Johnson Evinrude Gasket Sealing Compound. It is in a 4 FL OZ can (118 mL). Make sure you get the can with the brush attached to the lid. PN number 508235
