1987 50hp Evinrude E50TLCUD Thermostat Replacement

Thanks guys, learned something new today. Looper vs crossflow.

Ok so I put the seal flange in backwards. Can't undo that. My thinking was with the flange point towards the block the thermostat it sat in there better and did not move around when assembling. At least anyone with the same question in the future will find this thread and do it the right way. Based on what I saw removing the old one, I suspect it probably does not make much difference. The old one I couldnt even figure out where the flange went.

I am hoping to take it out on Wednesday for sea trials. Please please please let this fix it. I am tired of it stalling while trying to dock. I got really good at "not going any faster than you would want to hit the dock".

Why would you not run some kind of corrosion blaster through your motor when you haven't even diagnosed your motor. Nasty looking t-stats tested fine, right? The water orifices in that motor are not very big...plugging is easy.

That motor is not ready for fishing.

The old tstat was stuck closed, I finally got it to open at around 170 degrees.
