Ok, I have the 78 power head attached to the 59 lower unit 6hp/5.5 lower end. My water quit circulating. I just finished puling the motor apart, the Vanes on the water impeller are intact, it was replaced 8 trips ago. part 323596. Worked fine till i put motor in barrel to flush last trip. No water coming out indicator fitting or at exhaust. Splines are in good shape, Drive shaft turns propeller so shock is not an issue, no scoring on aluminium impeller housing insert in the water pump housing. Motor shifts gears and prop kicks water like normal. I blew compressed air through the lower unit water passages, through the pipe that runs up to the power head. I blew air in power head passages and air seems to come out.
What could be the problem?? Is there a thermostat stuck closed? Seems like it should be working fine. Any ideas?
Thanks, Azog
