Help! I'm looking for the Kubota Equivalent for a circulating pump and gasket (coolant NOT raw water) for my Universal M35B on my 1999 C36 MKII, hull #1754. Despite what's posted in the "Kubota Equivalents" section in this forum for this engine, I have a V1305 Kubota Block (SN WC7243). As most people know, the Westerbeke pump is outrageously priced compared to a Kubota equivalent, but a Kubota engine dealer can't cross reference the serial number and find the correct pump because Westerbeke controls the serial numbers for their "marinized" kubota engines. I want to buy a spare pump but am reluctant to purchase the one listed in the "Kubota Equivalents" section (#16251-73034) without knowledge that it is the right one for my V1305 block. Any help here would be greatly appreciated.

M35B Circulating Pump
The answer to your question, including the gasket number, should be in the C36 Owners Encyclopedia, accessable from the Quick Links list, right side of the C36IA homepage. The quick route to the homepage is by clicking 'Catalina 36 International Association' lower right of this page in the blue band.
And welcome aboard. I see you're from the Seattle area. What's the name of your boat, in case we're anchored nearby someday.

Welcome to the forum! I have a 2001 M35B Universal on my boat. Last summer my pump need to be replaced and I too went through the Kabo.ta dealernand was faced with the same challenge. So, I went to the local Beta Marine dealer here in NC and he knew exactly what pump I needed and as I recall it wasn't that expensive. It was a piece of cake installing it. I will look up his contact info for you tomorrow.

Larry: Thanks, our boat is the "Chinook", moored at Shilshole in Seattle. I'm dubious that the Kubota Equivalents quoted in the Encyclopedia section are correct for my situation though. It says there that the M35 engine is a Kubota V1200 block, and mine is definitely a V1305. I also saw another post somewhere that indicated the pump noted there (#16251-73034) did not fit the M35 engine. I'd really just like to get it confirmed.

From Google it looks like the V1305 was used in the B2710HSD tractors, so if you check that model number with a Kubota dealer you should be able to get the right water pump for it.
If you go here:
[url]http://www.kubota.com/part/PartsLookup.aspx[/url]
You can check the B2710HSD and it shows the engine model as a V1305-E-D12 and various engine parts that are commonly replaced.

Bud: This looks like a good link to Kubota parts, but there's no Circ (water) pump listed that I can find (unless I'm just not seeing it). Thanks for the link though. Through some other sources, I've identified 4 possibilities for a Kubota part number: 1) 16259-73032, 2) 16251-73034, and 3) 16241-73032 and 4) 16241-73034. I'm not sure what the first 5 numbers relate to, but if you ignore those, there might be only 2 possibilities: #73032, or #73034. Further thoughts? Thanks again.
Assuming that the B2710HSD is the right tractor and according to this page:
[URL="http://www.colemanequip.com/Kubota-B2710HSD-Parts/ENGINE-29917/WATER-PUM..."]http://www.colemanequip.com/Kubota-B2710HSD-Parts/ENGINE-29917/WATER-PUM...
there appears to be 2 possible pumps for that engine. 16251-73032 and 16251-73034. YachtSupplyDepot.com lists both of those pumps but they don't say what they fit. Maybe a phone call to them might be in order? Their prices are better than a lot of Kubota dealers it seems.
I just got a parts diagram from Messicks.com and here's the serial number breaks for the two water pumps for that tractor, the last number on each line is the serial number break. So motors with a serial number lower than 1U7903 use the 2nd part, ones above 1W0006 use the first part.
16251-73034 010 ASSY PUMP WATER >=1W0006
16251-73032 010 ASSY PUMP WATER <=1U7903
From what I see it looks like it is an interchangeable part and they just don't carry the 73032 one anymore, but you'd want to confirm that for sure.
They sure don't make this easy, do they?

Bob, remember that you've got a gasket that must be paired with the water pump you replace.

Torresen Supply, in their on line catalog, claims the waterpump number for the M-35 has been changed to MMD302503 for $255.98. You can call them at 231-739-8596 to be sure this is the correct water pump, it may be different for the M-35B.

I would bet that the price that you will be quoted at Beta Marine will be about half of what Torresen Supply will end upbeing. Larry makes an excellent point, make sure that darn (rather expensive, as I recall) paper gasket fits perfectly. Good luck with [B]that [/B]project because we all know, there will be [B]another[/B] just around the corner. You probably think of it as therapy, which it is. I use to be a psychotherapist, and just messing with a boat is a lot cheaper than psychotherapy.

Bud:
Its been an interesting quest here. I've looked at your posts and done some additional sluething myself. Per Messicks.com, it would seem that the pump I need is the 16251-73032 based on my serial number. Per Frontierpower.com the 73032 has a 2 1/4" impeller; the only other possibility is the 73034 which has a 2 3/4" impeller. Beta Marine suggested (when I called them) that the only real way to know which pump I need is to measure the impeller (which I don't want to do until the current pump fails and I'm forced to pull it off). I'll call Yacht Supply Depot tomorrow and see what they say. After that, I may have exhausted my resources. I think its coming down to one of these two pumps though......and Duane's right.....they sure don't make this easy!

Mike:
The M35B, Universal Part No. is 200820, for $432.55. This is at least 2X the price of the same pump sourced from ANY Kubota parts dealer. This is why I started this little quest. However, with the help of the Forum here, I'm getting closer. I just need to find another M35B owner that's actually bought a Kubota pump and can verify the Kubota part number.

OK one last time.....and thanks to everyone below for the help in this quest.....is there an M35B owner out there that can clearly verify that the Kubota Circ. pump #16251-73032 is the correct pump for my V1305 block, SN: WC7243?
I don't know if this is applicable or not, but when I bought the spare circulating pump for my M25xp (kubota D950) last year, they had two pumps that fit that engine. One of the pumps had an outlet for a heater, or in our case, the water heater. The other one was blank. I guess lots of applications for the engines don't have heaters.
My guess is that this may be why two different pumps are listed for the M35B.

Bob, did you ever get the answer to your inquiry?? Or does anyone else know for sure which part number works? We've just been quoted a staggering price by the local yard for a replacement water pump for our M35B, so I'm looking around. Luckily the boat's not going anywhere for a while.

I purchased this water pump and replaced when I did my camshaft 3-4 weeks ago. I used all Kubota parts for the job and probably saved over $1300...
You are correct, there is a 2 1/4" impeller version and a 2 3/4... (mine was 2 1/4") and cost me $250 here in Canada.
My 1999 M35BC is a Kubota V1305D. There is a Kubota serial number stamped in the block just adjacent to the fuel injector manifold; mine was 16060.
Hope this helps.

Howard, we're in Edmonton where I priced the part. Our boat is in Sidney on the island. Where did you buy your parts? We can deal there rather than buying here and delivering. Thanks.
