This is a situation where the very first time I ran it, plenty of water was pumping, then it became sporadic, then drips, then steam, then nothing. I will say that the water tube is barely staying up in the upper exhaust housing. It doens’t feel as if it’s grabbing that rubber gromet at the top.
I just pulled apart a frozen 35hp parts motor to get better acquainted with these motors and see that pastic gromet. I can see how if the motor overheats, then the inner exhaust housing heats up, that plastic melts and/or the grommet deforms/stops water flow.
Either way I have to pull the powerhead and switch it with another because the front half crankcase orifice for the starter is no good, and I have to use this short shaft exhaust housing as per the customers request. So I’ll be examining that water tube and grommet. Hopefully the lower exhaust tube screws aren’t stuck. Will report back tomorrow. Beach time for now!
Dan, where is the stainless exhaust baffle you’re talking about (parts diagram #)?
This motor is pumping basically nothing at all up from the gearcase, so its something before the overboard water indicator that is the culprit.
Fleetwin, this does not appear to be a salt motor, and it looks to be with an intact original exhaust/cylinder head.
