Hello everyone. I bought a 32í Carver Mariner a while back and Iím finally getting around to some long awaited maintenance
items. The latest is the electric marine head
. I have all the receipts so I donít know what the original head
was but it has the Jabsco
conversion kit. I know because I found the box and receipt. I bought a wet end kit for it and decided to service
Everything went pretty well. Only issues once inside the pump
was a massive hair ball wrapped around the chopper plate and a ton of hard water
deposits. I soaked the pieces I was keeping in vinegar to remove the deposits and reassembled. Went to hit the button and nothing. Rotated pump
from back shaft and hit the button again. This time is made an awful squeal. I decided I needed to lube it more. Tore it down, lubed everything up, and hit the button.
It worked...sort of. Through process of elimination and 4 more tear downs, I discovered the shaft seal
leaking allowing fresh water
into the waste. Took everything apart again and made sure all the mating surfaces were clean. Instructions called for an 1/8Ē gap between the impeller and the wear plate. With that gap it leaks
like the titanic whenever I was bench testing by adding water to the inlet. So I decided to press the impeller into the shaft seal
and locking the screw to keep it there. No leaks
on bench test. Put it back together, and hit the button...
leaks again, shaft seal. Confirmed this by filling the pump body through the inlet while blocking the outlet. Iím at a loss. Iím on tear down number 7 on and have been working on this for about 12 hours total. Am I doing something wrong?
