Hello all! My first time posting here but been reading for awhile...So I have water dripping out of my raw water pump weep holes at high RPM, which is dripping onto my belts and spraying all inside the engine compartment (fresh water thank god). I replaced the impeller and o-ring gasket and still happening so I'm thinking of attempting to replace the pump seal that goes around the shaft that turns the impeller...

Can I do this without having to pull the entire pulley off the engine block? I'm somewhat mechanical but do not have bearing pullers, etc...I realize my bearing may be damaged but I would like to try the seal first to see if the leakage stops and then assess any bearing noise or issues.

2007 or 08 Volvo Penta GXI-H EFI engine with DP outdrive.

Any advice would be MUCH APPRECIATED :)

Thanks so much for all that...Unfortunately the service manuals do not cover the GXI-H model for some odd reason. I did watch those videos and it seems I should be able to replace the seal without issue...Another question...is it advised to add any lubricants into the top weep hole of the bearing housing to help lubricate the bearing behind the raw water pump? Thanks again!

Did you mean there is no need to add any oil or lubricant into the top weep hole?
When I install the new impeller pump shaft seal should I put any lubrication on that seal on the shaft side or the back side that will back up to the bearing face?

Thanks!

So I was able to replace the seal without any major issues and it solved the leaking water from the weep holes issue. I did spray some WD-40 white lithium grease inside on the bearing and also into the weep holes just for good measure.

One thing I would like to warn all of you raw water pump impeller folks is...when I first had my overheating problem I pulled my impeller and looked at it..it looked fine, no broken or work fins...all in one piece...which made me think it was probably my thermostat. After further investigation I found that the tined gear inside my impeller had actually broke loose from the rubber part of the impeller fins...which was very deceiving and I only found this by mistake. So when the crankshaft was turning the tines gear the fins were NOT turning !!! This is something I will now lookout for.​
