Cost 3YM raw water pump

[charles_reed]

I've just done the costing exercise to rebuild (using just body and faceplate) the Yanmar 3YM water-pump.

Parts cost (mainly from Aquafax) £90.87, new pump (from Marine Power) £150.69.
Both prices ex VAT but delivered.
I'll probably source the bearings and seal in Greece (cost €5.80 cf £18.37 in UK) and rebuild using the old (slightly tatty) shaft.

Thought the exercise might be of interest to others.

I have all the part numbers to ask Aquafax for......

plenty of previous posts, just do a search...

If the shaft is tatty, the pump will probably dribble.
The jabsco on my engine wants >£60 for a new shaft I think.
Got a friend with a lathe?

Thanx so do I - only posted for the benefit of others - need no help to make up my mind

Not so, the tat is on the two ends - where the impeller fits and the other end, where the pulley (a poor, ill-designed and ill-made) pressed steel 1/2 flat fits.
The price for the Johnson shaft is £18.17 including VAT and you'd have to start with 25mm dia bar to machine from solid, 85mm length of 25mm 316 bar - you'd not have much change from £15 from a stockholder.
