Hello All,
I'm looking for some confirmation before I pull my rebuilt water pump out. I have an early A-4, raw water cooled, with an Indigo Thermostat plumbed into the manifold output. My water pump output has been anemic for a few years and when there was water coming out of the weep holes in the pump body I got the MM rebuild kit. The rebuild went relatively smoothly and the reinstall looked good. The block was full from the 5 gallon bucket on the cabin top and then I switched back to the through-hull input. I was able to get some water out the exhaust but it pooped out.
I have blown out the pump inlet hose, through the strainer and out the through-hull. With the back plate off, and the through-hull open, water flows freely out of the pump. I disconnected the bypass (from the pump output to the thermostat) and put a hose on it, then clamped the output to the block. Cranking over the engine, nothing emerges. I rechecked the impeller, again, and it is fine. I am ready to pull the pump and send it to MM to confirm that it actually works (hoping they do that). Before I do that, I am soliciting advice - what have I missed? Is there something else I should do before blaming the pump rebuild and finding a way to test it out of the boat?
Thanks in advance,
David
