That is my pump exactly Tony and it was the packing that was impeding the shaft turning, All sorted now, I also managed to aquire a brand new one, Surplus to requirements now lol.

Just sptted another one on the Ebay link for £80 and it's exactly the same as mine. If I cant fix mine I will have to dig deep and swallow my sorrow, LOL.

Do I need to do anything to the shaft before replacing the packing and the nut. The pump you have pictured is the tempory replacement I have at the moment but not enough water is getting through.

I have managed to loosen the hexagon nut and it is now turning much better.

That's virtually the same but mine has a screwable grease point in front of the impellar unit as well. I have tried to undo the larg nut but it's solid. Thanks for reply and all your help. It's much appreciated, I will continue to try to loosen the nut and order a new impeller, Thanks again.

Sorry cant upload pics. Its a raw water pump that draws water from from outside the boat and it feeds a bullman and then mixes with the exhaust emissions. It is a Jabsco. It also has two greasing points either side, I have cleaned these and filled with fresh grease and the pump has become more easier to turn but not exactly spinning.

Hi, I have a 1500 BMC engine and the raw water pump as jammed, I stripped out the impeller and it is still very stiff to turn, Any suggestions would be greatly appreciated.
