yamaha 2.5hp stopped on a hot day

Success!

Ran 45 mins each way non stop in 25 degrees ambient and never missed a beat.

I think it was due to impeller fragments getting into places they shouldn't.

It's a very economical little motor. Even running it with the fuel cock shut prior to putting in the car, takes ages.

(It probably ran fine as this time, I had plug socket, 10mm socket and temp gauge with me in the boat....)
