Yanmar 315 leaking water pump
I have a 2004 Mainship Pilot 30 II with the 315 Yanmar. I noticed raw water dripping from the vents on the side of the water pump after shutting the engine down. It does not seem to drip when the engine is running. So far it's running in the normal temp range.
Do I need to rebuild the pump and change the seals? Can I do this without any special tools to pull the seals? I see there is a repair kit available.
