IMHO don't do it. Tom's energizer kit would be $ better spent.  I found a used split bowl berk with diverter had it rebuilt and had it cut into a hull(set back) for about 3 k.

JBP Panther Repower Package = Conversion To And Installation of New Berk Style Pump

Everything to gain (i.e. performance, parts availability/interchangeability) and nothing to lose. Well worth it IMO

so for around 3k i send you my pump and i get a new one with all the goodies ready to bolt into my boat right? my family owns a fiberglass shop i just dont want to deal with cutting up the bottem of the boat.

thanks for all the info.

Your family owns a fiberglass shop and you're unsure about converting to a Berk style pump???

I wouldn't say everything. It still uses the axial flow impeller used in the Panther, instead of the mixed flow Berkeley style. And, you still have any inefficiencies designed into the PantherJet suction housing and impeller, right?

Sorry but this is  incorrect "It still uses the axial flow impeller used in the Panther" The only thing really used from the Panther original jet in this conversion is the suction housing . All other parts and pieces are A/T dominator including (but not limited to) 17-4 race shaft ,A/T impeller ,Dom "+" bowl , different seal pack , Dom Nozzel adaptor ,steering , drive line upgrade, splashwell steering etc etc The kit is very complete and will "abandon" all the original pieces sans the housing ,those housing ,incidentally can even be used (once evaluated) if gouged and damaged from a previous impeller/and bearing failure that would normally require "sleeving" Hope this clarifies Tom

Aqua this 20' boat ran 55 before at 5600 + ,70 after at 5100 ,the jet you see coming out was a Brand new Bronze sleeved factory unit (with thier trim)  with only a few hrs on it Tom



Heres some more examples : www.jetdriveconversion.com

so you are saying this boat did 55 with a new panther and 70 with that berk style american turbine.. if i would get that much performance from the swap. i will go get my sawzall...

how does a berk style pump bolt right on to the panther housing. i am confuseed .. anyway the boat is going under the knife for interior this winter so that might be a good time to yank the drive out of there as well. since everything will be removed.

could you elaborate on this swap a little for me.

Fwiw, I did my install by single handedly. The most chalenging part (for me) was to get the old panther off,(friggin silycone )

I'm not sure what link you are refering to ,or if you were talking to me or Tom, but like Tom said a hole saw is the only saw you will need.

I didn't click on that but I bet you were looking a camomans ,panther to domi conversion, that included a set back. Like Tom said this deal is pretty much bolt on. The motor does not have to be moved. For me It dropped me 700 r's and I picked up 10mph or so. I's say it was worth it.

I bought mine from american turbine, before I had ever heard of Tom. I'm pretty sure mine was the 1st(out of production unit) the made from Tom's prototypes. Cost I'll leave that up to Tom. I upgraded mine with a stainless impeller.  A diverter is an option but I didn't have one. Jrork went with the same deal if I'm not mistaken. I've been looking forward to see how it improves his rpm/mph.

Well, it's a little too early to give hard facts since I've only ran it once and had my fair share of motor issues but what I can tell you is the the Panther Energizer setup that Tommy and Josh put together worked fantastic.

With my old Panther setup the best I could do was the mid to high 60's at 5900 rpm and that was after talking at length to Steve at Panther and doing a ton of setup adjustments and fine tuning. I tried the Devcon epoxy he sold me, cleanedup the leading edges, replaced the water seal, adjusted the rideplate till I damn near wore the threads off the boals and no matter what, it'd cavitate out of the hole and then run great before it'd start cavitating at the top end. Only reason it would stop cavatating at 5900 is that was where my rev limiter is set.  As it was, it stopped accelerating after 5300 or so and the rest of the revs were just cavatation

With this new setup that Tommy and Josh hooked me up with, I can stab it out of the hole with no cavitation and it would accelerate with a nice steady pull. I can cruise at 2500 or 3000 and stay on plane whereas my old Panther it would fall off plane so it was either idle or wide open to move around.

Reverse on the Panther was sketchy at best whereas this new setup provides an excellent reverse function.

We were having a ball running it this last weekend for the first time and with my son and I in the boat we could pull 5400 and it felt like it was hauling the mail (no gps at the time).

Unfortunately, we soon started having some motor issues and could never repeat the 5400 pulls but on Monday a group of us set up a speed trap with a boat that had a Radar Gun.  At a semi sick running motor we still pulled 74.5mph at a measly 4800 rpm.

So, I can't say what the top speed of our boat is but I can say that with the old Panther pump we were at 5900rpm and the mid to high 60s and now with the Energizer kit we're at 4800 rpm and 74.5 mph.......with such a nicer cruising and reversing ability.

So with all that said, I'm a believer in this Energizer setup given that it literally bolts to the boat with the same 5 bolts that held the original Panther pump in.  

Good luck with whatever direction you choose but I'm exceptionally happy with my decision to go with this pump setup and most of all, the decision to go with JetBoatPerformance.....damn good people
