Starts fine and runs for about 2-4 mins until it gets hot then fizzles out and quits. Won't start until it cools then process repeats. Not a fuel problem, ive gone through carbs and pump already. Anyone know what would be causing it to die when warmed up? Ignition Coils need replaced maybe?

Maybe the water pump.

Do you have water streaming out the tell tale?

These engines were designed to STOP when overheated.

---

At first no, but I unclogged with wire hanger. Now there is water streaming out of the back, but not with much pressure in my opinion. I don't know what it should look like though...Good to know it will stop when over heating, the lower unit feels hot to touch also. I should probably replace impeller?

---

Do you have any idea when the impeller was last changed?

If not, or it has been a long time, I would definitely start by changing the impeller.

---

Yeah, im going to do that. I got it running at higher rpm for a while and the stream was extremly hot, burnt my hand. I'm guessing that shouldnt be...Upon inspection of the thermostat, easier fix, it was not there and the chambers not wet at all. I think you're on to something Joe. Going to pick up impeller tomorrow hopefully. Is it normal to run these little older motors without the thermostat at all???
Thanks!

I personally wouldn't run without a thermostat unless it was an emergency.

Without the thermostat you stand a chance of running the engine too cold for too long of time.

ok, I'll be buying both impeller and thermo tomorrow. Anyway of cleaning the internal chambers where the water flows, im worried there may be a blockage that a new pump may not force out..
