Hi Rich!
Luck you, having a gear head for a neighbor. Guys like that often are more fussy about their work than the so-called pros working at the rebuild shop. Of course, having a local parts source is a big plus too. But most of us don't have the luxury of a next door machinist!

So, for the rest of us, I've mentioned these guys before. DEPCO Pump in Clearwater are the experts in all thing pump. They readily dispense expert advise as well as selling parts or doing rebuilds in their shop. They also have cross-referenced list for aftermarket pumps.  On one occasion they were unable to help me with parts for a recirc pump for my Volvo power plant.  (Apparently made from Unobtanium) They suggested that I contact a vendor they knew in Arizona!  Even had the phone number handy.

Last year I needed a new impeller for my elderly genset in the middle of our cruise. The local marina mechanic was unable to source one so I called Depco. They had it in stock and we had it overnight. Easy-peasy.

It would be a worthwhile exercise to check with them about availability and pricing of your Yanmar pump parts. If you call them, ask about the cost of rebuilding the pump. I've often found that, after looking at their price, it just wasn't worth my time to do the rebuild.

Good thoughts, Randy, and I did check in with Depco.  Their price for a new pump is four times my neighborhood rebuild cost, and they will not give an estimate for them to rebuild over the phone – they have to have the pump in hand before estimating.  With the cost of shipping and the delay in having the pump back in the boat (Even though I don’t have a schedule, I don’t like the thought of a powerless boat for a day longer than necessary.)  and their parts/labor markup, my guess is the rebuild cost through them would be several times my own, but if I did not have the help I do here in the ‘hood, I would consider sending it.  I think one of the larger savings, aside from the “free” labor of us two old retired Navy officers, I am getting is by avoiding Yanmar’s supply chain in obtaining the bearings and getting the very same items through a non-boating industrial source.

This repair puts me in mind of how my father (an airplane gear head of the highest order who built two planes in his garage) used to lend his 30 years of experience in Navy aircraft maintenance as well as his FAA license for airframe and engine repair to his buddies out at the local airfield.  He saved those guys countless thousands of dollars over the years.  So my advice is to make friends with your local gear head.  I like to pay it forward in my own way by helping several local boater friends in projects I am more familiar with than they are.  Now where am I gonna find room for a hydraulic press, and a sand blaster, and a drill press, and ……  Harbor Freight, here I come!  :)
