Found the bad pump. It was the raw water pump.Thanks for all the help. I went down today and took the raw water pump off along with taking the impeller out. I was able to move the shaft back and forth, had alot of play in it. Guys thanks again for your help. Mike
Mike, most or many of these lend themselves to a bearing replacement.
Often the bearings and seals are industry standard...... and are very easy for a major bearing supplier to provide.
FYI:
Depending on which engine model you have, some of these belt driven sea water pump systems can be circumvented in lieu of a crankshaft sea water pump.
I've walked many people through the procedure.
To do this, you must have a minimal amount of space FWD of the front crankshaft pulley, minus the belt driven pump pulley.
A friend of mine needed to replace a pump on his Merc 6.2L Horizon. Merc wanted over $600 for a new one, and the new pump was several weeks out.
We spoke, and I mentioned converting to the Johnson F6B-9 pump.
He chewed over the idea,
and that's what he ended up doing, and he's happy as a pancake with it.
Easy impeller access, and there is no belt tension side load to tug away at the shaft bearings.
This is a
Chrysler Marine engine related thread, but the front crankshaft pump idea is very similar.
Food for thought if nothing else!
