Need a Raw Water Pump Assembly

[BirdieNumNum]

2000 310 with twin 5.7 TBI B3s. My starboard engine raw water pump is leaking out of the weep hole. This is the pump that has the raw water impeller. Not the water pump on the engine. Should I get a reman or new? Where? I don’t have the presses to rebuild myself. Thank you.

I think you saying there’s water seeping through the front bearing and weeping out. I didn't know there was a hole...

I’d just get a new one because IMHO a rebuild isn’t going to last as long.

Proof the ser# is correct for your engine.

Got a rebuild kit for $100 5yrs ago and redid my port pump. Hasn't been a problem at all since....

The last pump I had to rebuild was for my Westerbeke Generator (raw water pump). I decided to just take it to a local machine shop. They measured the bearings/shaft/seals, ordered the parts and rebuilt it without any problems for way less than half of a replacement pump.

This is where the water is coming out of when engine is running. It looks like a weep hole to me. Not sure.

That looks like a different pump than mine so I'm not sure if that "hole" is normal or not.
