Hey folks,
I have a 1978 Evinrude v4 85hp motor and after storing my boat indoors for the icy winter, I changed plugs and restarted it today on the muffs. I let it warm up a while. It was working fine before I stored it.
In the past I thought one side of the cylinders seemed hotter than the other but not a whole lot so I kept touching both sides to double-check. Today one side got a lot hotter so much so that after about 5 minutes of running, the overheat alarm sounded. To the touch, the "cool" side got quite warm. The hot side was too hot to touch more than a second or two. It was HOT.
I have no idea when the impeller was last changed but the pee stream is strong.
Other related posts suggest changing the thermostat but the diagram on the Evinrude site makes it look like there's only one thermostat/valve so I'm confused why that would affect one side and not the other. Is that a simplified diagram and really there are two thermostats and valves?
Also, how in heck do you remove the thermostat housing? It sits sort of down in the bottom cowling bit. And is that spring inside the thermostat housing going to shoot all the parts into the bushes and be impossible to get back together?
Any other suggestions? Should I try it in the lake instead of hose?
Fortunately it looks too cold for boating for a while...
Thanks!
