Westerbeke BTD-8D Sea water pump, Westerbeke part # 33636 impeller part # 34440-gctid368560

I have had some impeller challenges with the sea water pump (Westerbeke part # 33636) on my 3818.

So Ii went hunting for alternatives other than the Westerbeke impeller part # 34440.

I was able to cross reference the par number to several different makes.

Here below is what I found at this very useful web page

Fact is - Globe impellers fail on the Hino mains due to their inherent design.

I am not aware of how they work in the genset so take it for what it is worth.

Hope this helps

I installed the globes on my 3818 hinos, i could not get the water to draw thru. I tried everything i could think of , finally thru them away went with the jabsco's

[smitty477]

The short version -

I thought I had posted this enough in the past but perhaps not.

DO NOT use Globe impellers in your Hino engines.

They will fail due to their design in less then 30 hrs and leave you stranded or with a major repair bill.

After failure we took them out and carefully dissected the failures and found specific issues with the design.

Customer service at Globe requested them back along with my leter and sketch (but I kept one as a sample).

At the time of failure I tried to implore Globe to 'contact' as many Bayliner owners as possible to warn them.

They 'offered' me free product and 'consultation' fees as an alternate which was categorically declined.

Hope this helps

I started this string to help out members who needed alternative brands with non Westerbeke part numbers that would be acceptable cross references to the Westerbeke OEM impeller part number.

Someday your impeller may fail & you might not have a spare aboard. So you call West Marine 'cause they are usually open. Good luck getting help with a Westerbeke part number. However West Marine does carry some of the part numbers in the original post

Now let's see what we can learn about the accuracy of these cross references, the suitability, success & reliability of the other manufacture's options. We now have 6 brands to choose from and to try out and we have part numbers for all 6 brands.

The other impeller manufacturer part numbers are from:

• Westerbeke OEM
• Jabsco
• Johnson
• Perkins
• Volvo
• & last but not least Globe

This is excellent information and well appreciated - thank you. It is always great to get cross reference sources for spares and these tend to be a higher user so they are more valuable sources. I do not know what would happen with a globe westerbeke replacement as it has never been tested on our boat

On a separate note there is no good way to easily tell that a Hino Globe impeller will fail when you look at them. So an unsuspecting user may think that we are reffering to a 'slightly' different service life on the globes.

That is not near the truth as they litterallty spin the hub in less than 30 hrs use from new.

Hope this helps

The $50 Westy that came in the red box had a Johnson part number and I asked to see that one. It came in a plastic bag including the paper gasket for $30. Same impeller. Johnson 09-810b-1.

My Westerbeke also uses those impellers. Mine last a long time, but I always carry spares.

The shaft seal also failed on my pump, so I now also carry the puller tool so I can swap that part.

I just did a quick look to see what impellers are going for now.

Not much change, Westerbeke number on Amazon is $37, Johnson about $17 at several sources.

A couple years ago my gen intake plugged up with jellyfish. I went into Pender Harbor, BC. for a couple days and while I was there I cleaned out the system and replaced the impeller. I thought I only had one spare and as long as I was close to a chandlery I'd just buy a new one and keep my spare. I paid 90 bucks for the thing. That's what I paid for the last complete rebuild kit I bought.

A few days later I was digging through my kit looking for something else and found I had 4 spare Westerbeke impellers onboard. It was time to update my inventory.

Thanks for the cross references its good info to have.
