For the more machinist orientated, would it be feasible to tap 3/4" NPT threads into the existing pump if it's not bushed or are the 1/2" NPT to close in size? My pump is older and I don't think it has a reducing bushing.

The pump you linked to is a G-65, that's why it has bushings. The original F-85 had 1/2" ports, and there is definitely not enough meat on it to drill and tap to 3/4 NPT.

The 1/2" NPT nipple suggestion is sound. A few years back when I replaced the manifold on my 1978 Atomic 4, and found that the cooling hose connection from the manifold to the exhaust elbow was, in fact, a cut-off pipe nipple. In fact, I built up a replacement elbow using 316 SS pipe nipples and fittings, and silver brazed a cutoff 1/4" nipple into it for the water.

[QUOTE=jimbunyard;3079082]Let's try this one last time.


Westerbeke's knowledge of their market is beginning to show.



Jim I feel your pain I enjoyed the bit about the market

Repeat cut: one threaded end off a nipple as shown in the link & push your hose onto the smooth pipe looking part
See post no.6 for instructions
Or just buy the Westerbeke part

This has to be the most cost/time effective solution!

The PO had used tape over 3/4" hose barbs! I had a plumber fabricate some out of 7/8" copper tubing for a stopgap. They've worked but they're relatively thin and I have had one fail. I'd like to use a proper heavy bronze fitting for peace of mind. In the meantime, I still have a couple of spares from the plumber.


Yes, I know can spend $140 (plus shipping) to get one from Westerbeke, part #32230. It's a really nice-looking machined fitting, but I'd rather not patronize thieves if I can help it. I don't doubt this engine could've been plumbed with 3/4" hose but was instead done so with the odd size so that I'd buy from them.



Does anyone have any ideas besides swallowing my pride and forking over $150 for a small hose barb? I've searched high and low on the internet.

I have been boating (small motorized boats) for 50 years and often get upset over the price of parts. If, in the end, I can't find a part for a reasonable price; I bite the bullet and get on with the enjoyment of my boat. I feel better much sooner that way. These things remain in the back of my mind for the next time I buy a boat.

That said, a machine shop may very well be the way. The setup charge will probably be the biggest expense and you may be able to get a spare for not much more. Maybe get a few more and get your money back selling them on eBay.

Probably easier and quicker is to find a welder with st.steel TIG and get him to put a run of weld arond the barb area of the stainless offering. 20 mins and some cash in hand..bingo end of problem for years !!

Good idea. My main point was to not let such things get to you so you're unable to enjoy your boat. Sometimes you you just need to take it in the you know what and move on.

Are there any Europeans or Asians out there that can chime in on this hose issue. Does the rest of the world use US size hoses, or are they using millimeter ID sizes. Just last week I couldn't find marine fuel hose that would properly fit on a new Kubota 21kw generator fuel return line barb. Standing by.

The rest of the world uses the metric system.

Not sure my pride would be hurt paying the manufacturer their reference retail price for a part that they have sourced in the proper material, absorbed cost of purchase and storage and are willing to ship to you. Their policy of customer retail provides individuals access to parts while protecting their inventory stocking distributors. IMHO that is customer service. Not sure they deserve bashing.

Universal sell the same part for $25.
My pride would definitely be hurt if I paid Westerbeke $140 for it.

bcboom,


The universal fitting is an 90° ell and the westerbeke one is a straight barb.


I think the universal fitting will work though. I just have to check that there won't be anything to interfere with the routing of the hose when I get back to the boat. Can't do that from here. I have two ports to try when I get there and only one needs to work.



I think it's the best choice considering cost, fit and time like you said earlier.



I'm grateful to eceavchss for posting it.
