YanMar 3GM30F water pump impeller

They're ok, Robin.
Robin could I ask what you paid for your impellor? I've previously changed mine every year but stopped doing so 2 years ago (I recycle the old ones) when the UK Yanmar dealers wanted £45 for one.

Vyv's post reminded me to ask if your impellor has a keyway? Mine has and it is something to do with EU ....

$38.48 or about24 squids (stupid keyboard has no pound sign) plus 6% sales tax but no VAT of course to add and I don't know about the keyway until I get to see the bits

I don't know about a keyway, I just found a couple of old impellers on bord that have a threaded rod through the centre. I also found a poly bag with a few o-rings in it and what seems to be a few spare pump coverplate screws. Oh and the engine number is E 21772 on the plate so the 'E ' may be the European assembled version?
 
Thanks that is a useful link for lots of info. I think for safety I'm going to have our engineer fit a new impellor and once the correct one is identified and sourced get a spare, that way we can have confidence it is correct because right now it is perm any one from multiple options of impeller and gaskets/o-rings, not helpful. I like the speedseal idea but in our cae think by the time we have taken the pump bracket off and rotated it for access we don't need the Speedseal as we can easily reach all the screws anyway.

More up to date information. I just received the new (genuine Yanmar part) impeller and they modified my order when they knew it was for a euro assembled Yanmar ( engine serial # prefixed by 'E') the impeller cost $17.41 and I bought 6 O-ring seals at $2.71 each , total cost inc 6% sales tax and shipping from Fort Lauderdale to Daytona by UPS ground was just $51.89 or about 32 POUNDS sterling which as suspected is way less than it would cost in the UK. the company is Scott Marine Power, 3786 SW 30TH AVE Fort LAUDERDALE Florida 33312 (www.scottmarinepower.com), they are on Ebay so may agree to ship overseas if asked? They actually ordered the correct parts for me from Yanmar as the price included a mail cost from Yanmar USA of $2.41.

Those are not the part numbers for my Yanmar 3gm30F. I was warned by someone on the forum that some Yanmars were 'assembled in Europe or the USA to avoid import taxes on Japanese ones and that basically the only 'assembly' was to bolt on a local water pump type (Jabsco , Johnson or Sherwood). European assembled engines have an 'E' prefix on the serial number. Our 1998 beneteau was built in France and exported direct to the original owner in the USA, the Yanmar is an 'E' prefix one and the impelller part number is 128990-42200 and has an 0-ring seal part number x0506597-01 not a paper gasket as shown in the video. This pick 'n mix is very confusing but forewarned is forearmed. Presumably the part numbers in that video are for USA assembled Yanmars as it seems like an American video? There is a difference also I understand between raw water engines and freshwater cooled ones like our 3GM30F ( the 'F signifies freshwater cooled). Regardless the video shows what is involved in the job.
 
I reckon that for peace of mind when off cruising, perhaps now is the time to order a complete pump as well, given the $100/hour engineer 'rate' and typical 30% import duty to the Bahamas...

A sensible extravagance perhaps?

I have replaced seals and bearings v inexpensively, carry the spare spare ones and it is an easy enough to do task in the cockpit with patience, tools and stout engineers vice and drifts, but perhaps not just yet after the unfortunate stroke ?

I might do that but the USA Yanmar pumps are not the same type as the European ones I believe so I would need to order one in. At tis point I just wanted to be sure we have the correct spare impellers and faceplate seals on board. 18 months on now from my stroke I could probably do the job myself if an impeller fails but if I have to pay a local then having the correct parts available is a good start.
