1987 50hp Evinrude E50TLCUD Thermostat Replacement

[FishAtFive]

The problem of it idling poorly after warming up has never went away and no matter what I've replaced/rebuilt the problem persists and frankly I am just done with it. This weekend I am pretty sure it got stuck closed because it lost all accelleration and the temp alarm went off. So here we go.

I'm going in, wish me luck. Will post updates here.

Not even an option, the previous owner did a **** poor job on a through hull and the transom rot is up to one of the four mounting bolts.

Did you ever post the actual compression values on this motor?

I believe so. If I recall correctly they were between 140 and 150 and +-10% of each other. I checked twice, when I first started working on it and after the last time it overheated. Disclaimer: crappy amazon tester used.
