Was out this AM. 1995 60HP Evinrude. Was running ~4,500 RPM when the overheat horn started screaming! Ramped down to idle and shut off engine. Saw steam coming out of the pee-hole! Took a look and I had a wad of vegetation that was clapped down on the intake. I removed it, waited, then fired her up - pee started and horn did not come back on. Felt the head and it was hot, but not on fire. Motored back in (about 2 miles) sweating like crazy, but there were no issues. It ran just fine.

So, after reading up here, I re-torqued the head (it was fine), inspected the spark plugs (they looked fine), peered into the cylinders (nothing unusual), did a compression test (all three cylinders were dead on 120 PSI which is what they've been since I owned the motor), and inspected the gaskets (they look fine). The nice shiny black paint I used on the powerhead is fine without any dulling or visible signs of cooking.

So - I'm inclined to say we're all good and go forward without worry. I haven't found anything aside from these checks (unless one fails, then there's lots of follow-on advise). Am I missing anything? Did I dodge the bullet?

Thanks!

Looks like you did a good follow up on your over heat situation. :)

I run my motors in weeds/moss conditions a bunch. If you take care of the situation immediately when the temp alarm goes off, things will usually be ok.
I have had it happen once, that weed material clogged up my thermostat, but that was just once.

Re: Overheat - weeds got in water intake

I've run through kelp when I lived in CA and now weeds in the Potomac. I've had 'em bunch up all around my skeg - but never once actually restricting water flow. When I motor through the weeds, I always go slow and keep a watchful eye on the pee-hole. I did again today and after getting on the channel, I pulled up the motor and defouled it... I think I must have gotten something in the actual channel that just hit it right (or wrong actually). I think I was lucky I had a 50:1 mix running through the engine (in addition to the OMS) which I was trying to use up.

Well, I'm going to count my blessings and hope nothing is seriously impacted on the motor. Thank you OMC for the alarm!
