Yanmar 6LP water pump & impeller sourcing
Hi all -
I normally used the SMX impellers from Tony Athens, but he does not appear to carry them anymore for the 6LPs, so I bought a couple generic ones off of Ebay. Normally I change impellers annually and there is not much wear or damage (with the SMX ones) but my engine overheated yesterday and when we checked the impeller, all but one blade was gone (after 9 months of use)
Is there a good source for high quality OEM impellers for the yanmar 6LP? (119773-42600 -> YAN-119773-42640)
Also, am considering buying a new sea water pump. I researched a bit, and it seems like Johnson makes the waterpump for Yanmar (yanmar 119773-42500; Johnson 10-24493), but I'm sure if this pump is still available, as I read on one of the sites that the yanmar pump was no longer produced (which doesn't quite make sense to me, if the 6LP engine is still being produced). I also do see JMP aftermarket version JPR-YM06LPA.
This JMP version looks like the main option, but just wondered if anyone had real world experience with it.

Re: Yanmar 6LP water pump & impeller sourcing
Gary,
I have a 6LPA-STP Yanmar..........this spring I replace the water pump and impellor with Yanmar parts. FYI, my engine ran at a constant 180 degrees since I purchased it almost 3 years ago, since the replacement, it runs at 165 degrees. I also flushed the coolant and place new coolant, but I attribute the drop in running temp due to an new water pump.

Thanks - good to know! Did you get the parts online or at a local dealer?

Re: Yanmar 6LP water pump & impeller sourcing
Replaced mine a few years ago with the Johnson Pump (Johnson 10-24493-01, 10-24493-02 with inlet/outlet). Can't find the receipt, but I know I just ordered online, from Pumps Direct, Pump Vendor, or similar site. The JMP pumps do seem easier to find

Scratch that, found the box and I had actually bought the Yanmar pump assembly (still made by Johnson Pump). It did not come with the drive gear, so I reused the old one.

Re: Yanmar 6LP water pump & impeller sourcing
Thanks! Surprisingly, the yanmar branded pump seems quite reasonable. Almost makes me suspicious.GSSeattle wrote: ↑Fri Sep 15, 2023 4:59 pm Scratch that, found the box and I had actually bought the Yanmar pump assembly (still made by Johnson Pump).

Re: Yanmar 6LP water pump & impeller sourcing
Ended up ordering a JMP pump from Big Blue Ocean Marine. Was a bit more expensive at $580 but the international shipping cost was reasonable, and they had spare impellers in stock (which other sites didn't). The JMP pump also included the gear which the Johnson/Yanmar pump didn't seem to.

Gary,
Niemiec Marine who replaced my pump and impellor are Yanmar dealers, they have all the parts in stock, and, lucky enough, they have worked on many Albins also, in fact one was in their yard when they worked on mine, the engine was removed and a new oil pan installed I was told.

Re: Yanmar 6LP water pump & impeller sourcing
Just for reference. The pumps are easy to rebuild. It’s just two bearings and two shaft seals. Just be sure you use stainless springs in the seals as they come with steel as standard. I rebuild mine when they eventually fail. It’s easy to do but then I do own a factory with all the necessary equipment but any machine shop should be able to rebuild one for you.
