Raw Water Pump-Yanmar 4JH3E

[Blue Reef Cafe]

Hi,


I recently went out for a sail and came back to an engine bilge full of salt water. I have traced it to the water pump">raw water pump. I have the service manual but I think it assumes you are in an air conditioned workshop with a full set of Snap On tools. It does not address how to remove the pump which is, of course, on the non accessible side of the engine. Is it simply a matter of undoing the four mounting bolts which you can't see, and the hoses and removing the whole assembly? Is there a full rebuild kit available - or a reputable non OEM kit that will work?




Thanks in advance
