Re: Water pump theory question

[wetwillie]

I have no problem with trying eliminating other possibilities before resorting to taking the head or exhaust cover off. I like your ideas A LOT and will try the garden hose to water tube adapter. I’ll run water through it, as suggested, w/o the engine running and then with it running and report back with my observations. I am curious why you stress using low pressure. Please explain.
Also, to answer your initial questions. I ran the motor before replacing the impeller and had the same problem as I have now. That is one reason I replaced the impeller (aftermarket, BRP, I think). The impeller vanes were bent but no cracks, etc. The other reason was that I felt it best to R&R it for the sake of peace of mind. I initially ran it on water muffs that were duct taped in place. It was only after reading someone’s suggestion that I immerse the lower unit in water that I tried that.
To be contd.
THANKS!!
