Help Rebuilding 1976 mercuriser mie 233 raw water pump
Posted: Sat Nov 17, 2018 6:36 pm
Hi this year I had a heating problem with my mercruiser 233, (Trojan F26) so I replaced the impeller that had failed. After the replacement I noticed my front bilge was running more frequently and so when I brought the boat in for winterizing I noticed there was a stream of water coming from a hole in the pump casing. It appears the hole is intentional and I believe it may be a weep hole.
I have attached 5 pics 4 of the pump and one of a parts diagram. My questions are What are steps to tear down the pump? Is the weep hole stream the sign of an inner seal failure. I have two manuals on the mie 233 but there are no procedures to pull the pump apart.
Rather than guess and create greater problems I thought I would submit this question to the form.
Thanks in advance for the help.
