My new pump

[BrendellaJet]

Just picked this up from MPD. Stage 3 Jacuzzi 12WJ. Jack still has the intake, he is making the loader and said it sould turn out better if I left it with him. Heres some photos of the before and after. I was going to have it powder coated, but Jack sold me on painting it instead, so thats what I'll do. Ill probably just paint the bowl, looks like the suction housing will clean up just fine...

Jack cut off nozzle and part of the flange, and welded on this adapter so I can run the Berk style diverter and droop. Here are some before and after shots of the intake with the max set back option:

Heres a few other miscellaneous shots...
Jack redrilled the loader pad with larger bolts, and added an extra hole for strength(stock there are only 2)

Damn thats a big handhole!

[BrendellaJet]

Yeah, with the setback, im not sure if its going to be useable, my measurements suggest that its going to land half way through the transom :( Ill figure something out. Probably extend the hand hole so that it comes through the top side of the hull.

[BrendellaJet]

Im curious to see how people keep their hand hole functional when it lands in the center of the transom, any way to do this?

[dgie]

2 questions how much did all that work cost and what does a ride plate do?

[BrendellaJet]

The work cost $1500. Jack has cheaper routes to go, but for my goals, the stage 3 rebuild was the way to go. Every piece of the pump has been massaged into a beautiful piece. The stock jacuzzi WJ pump is not a real performance piece to start-now mine is. As for the ride plate, others are more qualified to explain that than I, my understanding is that it will help lessen the drag created by the pump once the boat is aired out-especially at higher speeds as the wetted area decreases. Oh yeah, one more thing, also included in the price was unlimited answering of my questions by Jack. He is a great guy to talk with and has a lot to offer to Jetters. He takes the time out of his very long days to answer my questions in depth and has pointed me in the right direction so that I can achieve my goals.

Probably extend the hand hole so that it comes through the top side of the hull. I've seen transom adaptor plates made for setback pumps (I think that's some of MPD's work). They're recessed enough so the Berkeley handhold can still be used, but it's a lot smaller than your jacuzzi's. I had my Berk pump setback where the handhole is half in and half out which renders it unuseable. In the time I've owned my boat I've never once used it anyway. If I get something caught in the pump, I go through the intake to get it out.

[dgie]

I hate to keep badgering you on this, I also have a 12/wj and was wondering with what he did, how does it make it a better performer. Also Would it not be cheaper or better to go with the American Turbine Energizer kit, then have all that work done.

[Bense468]

yeah talk to jack he has the recessed (sp) transom adapters. Now I am not too sure if will work with your setup, but its worth trying.

[HammerDown]

I actualy made my own...its based on how MPD fabs them up. It came out first class all the way. I belive It was 6 pieces of Aluminum I had to use...fabed it up first out of cardboard, then cut it out of 1/4 and 1/8" Aluminum sheet, welded it up and had it Powercoated...perfect!

[BrendellaJet]

Yeah, I guess I could go through the intake to get crap out of it, but I think the loader will be in the way. I have had to use the hand hole before, so I would prefer to keep it workable. Im sure i have seen pics of the transom adapters you guys are speaking of, guess Ill just have to wait until the pump is back in to see how to go about it. Thanks for the reply's.
dgie, I think the AT energizer cost the same amount as this work did. Considering you dont even get a ride plate or shoe out of the deal, MPD is the way to go( the detail work that Jack also does is far better from the stock parts I have seen). Dont be mislead by the uninformed. The 12WJ is a solid pump. Jack told me that the berk pump were always a little faster, but only because people did not know how to make them work. This thing should be a berk killer now! :D

Now I can finally start putting this thing back together!

[Peterbuiltmn904]

Please let me know what the phone # and the address for the company that did your pump work. I have the same pump and woud like to have it re-worked, also.

[ole war horse]

Looks dam good and I am glad to see guys do detailed work like this and show love for there jets

[TRG]

you know,...i have a buddy that i turned on to jack about a month ago to have his jacuzzi pump rebuilt and needed a new input shaft, jack said that it would take about a week or two, it has been over a month now and the problem he (MY FRIEND) is saying is that jack is finding it hard to find an input shaft. is it true that a jacuzzi input is the same as a berkeley? i guess what im trying to say is, are all of theese shafts universal? and if so are they as hard as jack says they are to find? because at the last pomona swapt meet a guy had about 4 of these input shafts sitting there? i dont know much about pumps but any info would be greatly appreciated!! dont take this post the way that most of you usually do j/k todd

[Duane HTP]

No, the shafts are not the same. The Jacuzzi shaft is a tapered shaft where the impeller goes on. And a LOT more expensive.

[TRG]

My bad , but my real question i guess is,...are they very hard to come buy and if you have a ballpark fig. how much? thanks for the quick response! todd

[Duane HTP]

I'll try to look one up for price and availability tomorrow morning before I leave for ILL. for the races at New Athens.

He is in Costa Mesa on 1760 Monrovia St. Unit A-7. I am pretty sure its between 17th and 18th street. # is 949-631-2040.
Im sure there are many people who do good pump work, Jack is one of them. He is a good guy and likes to talk if you have questions. Very knowledgeable and patient with those of us still learning what makes these things tick.

hey hb jet!!! you said "how the v-drive guys aways have to change gears and props" but man we don't have to to all that stuff lol....looks like jack is the man tho. all you fast jets get hooked up at jacks?

[Peterbuiltmn904]

You guys have to blueprint the V-drive each time you assemble dont you? Thats all this is doing, along with some performance mods because the stock parts dont suck very well... Lots of fast jets go to him though.

[Bow Tie Omega]

Bri, that work turned out great, that impeller does not look the same at all. He really opened things up. Now you just need a motor to turn the thing. Next summer we will be set. Joe
