Leaking water pump help .

[The Jester]

When i got back in today i noticed quite a bit water under the engine. I left the engine running and on looking over the top of the engine, there is water dripping badly from the water pump, think its called a Jabsco.
Anyone know about these :question:, the engine is a Nanni 85HP, are they expensive :question:, they certainly look a swine to get at...

Hi mate,

I had the exact experience a few years ago (will try and dig a few pics out) it was the bearing race inside the pump that had collapsed.
I ended up getting a new pump complete (about £150-£200 if I remember correctly but that depends on model)
I did strip down the old one but found that there was some damage inside (along with the extra damage I caused trying to knock the bearing cage out) and that it would have cost as much to replace the bearings/seals and impeller as it would to buy a new one complete.
This happened to me in the cold of winter so I was unsure whether it was simply wear and I`d not noticed the leak or in fact if it had been Ice formed in the bearings then crushed with engine starts.
Been fine since new replacement, but I do keep a check for tell tale leaks.

Good luck

Same happened on Shady, the impeller was fine but a shaft seal and a bearing had gone. There were kits available but we bought a shaft seal from ebay for coppers and a bearing for a few quid, been fine ever since.

Best find out your exact pump model No. and have a search on the web.

Thanks for that, it looks like its leaking from the shaft from what i could see, i'm going to try and take it off tomorrow and get the numbers off it, where is the nearest place to get a new pump :question:

 

[Norman]

I got mine from Powerhouse Marine but as keith says if theres no damage to the body and the shaft then best look around first for spare seals and bearings. Not a difficult job to strip down and mine luckily was more or less on the top of the engine so not too bad to get to.

[The Jester]

Thanks for that Mark, been in there a few times but never gave them a thought....

 

[mark]

was in there yesterday, having a good old rummage around the darkest recesses - my idea of heaven been left to hunt around for a bit.

 

[The Jester]

Yeah, nothing organised in there, but that makes it all the more interesting. Saw your ad for a trailer, what sort of boat are you bringing down from scotland ?

 

[mark]

An old wooden one 18' yawl

 

[The Jester]

Might be able to help you out with a trailer, i've got a rollercoaster 3, twin axle, its a breaked trailer but all the brake parts are in a box, in my garage, as they sieze up when left in the drums, dunno if you're any good at assembling brakes or you could just use it unbraked.......

 

[mark]

oohhh.. .be more than happy to rebuild the brakes for you for a loan of it for a weekend plus whatever suitable recompense/widgets/beer tokens I can push your way

 

[The Jester]

When are you looking to use it Mark, its in the compound at Sunderland marina.

 

[Norman]
