possible overheating problems

[grahamcamm]

I have had a WSPCL now for a few years and it always has a good healthy water outflow, easily as thick as a pencil.
Yesterday, an hour before dark and over a mile from my launch site it just suddenly stopped pumping water. With no other means or help I just had to chance it so turned the throttle down to half and luckily made it although it did steam the entire journey.
I stripped it today and the water pipe had come out of its olive and nut fitting at the base of the cylinder block.
After re assembling, it started up and pumped water perfectly again and ran it for an hour in a wheelie bin with no problems.
My question is, could I have caused any overheating problems that may rear their ugly head in the near future by running it with no water flow.
The air temp was 46f and water temp was 40f

I personally would say thay if it did not seize, you have caused no future problems .

It is good idea to lock wire the union nut in place. Somewhere on this forum is a photo showing an example. Anyone have that photo?

Your motor should be fine.

had the same thing happen to my silver century.
When I owned my 1st seagull in 1974 I used to use it as a trolling motor, i didn't know anything about them then, with the trolling I would be running it at such low speeds the water wouldn't be pumping, when it got to hot it would just stop, the motor still turned easily but wouldn't start till it cooled down which only took a few minutes. never did any damage as it never actually seized from overheating, which is a good point about seagulls.
when the pipe came undone on the silver century I had to keep it running and kept pouring water over the cylinder with a small bucket I had every 2 to 3 minutes and it got me home, luckily it was only about 20minutes away
