I have a Berkeley 12JE with a 31 year old impeller on it. I'm thinking it's time to put on a new one ::) I can feel some burrs on the inside through the clean out hole.
Anyway to the question. I run about 5000 RPM's on top so would the original type aluminum be ok? I run a nice deep lake so picking up crap is at a mininum.
Where is the best place to pick up an A impeller and should I stick with a Berkeley brand?
Do I need the special tool to remove the old one or will a puller do it? Does the impeller need to be heated up to pull from the shaft?
The jet was rebuilt 5 years ago.
Thank you for your help

American Turbine,Dominator,Legend products (all represented by us) are by far the finest quality money can buy ,Aluminum is fine for under 500 hp
re pulling the impeller ,avoid applying heat at all costs ,once you remove the nut , a good jaw puller should do the trick , if you need to "borrow" or buy the "capture" type puller we use we can make arrangments to loan you one or sell it to you . Please let us know if we can help you ,check PMs cell number for the weekend Tom

Could you give me some prices on the impellers, which brand do you recommend?
If I go away from Berkeley will I have to mess with the wear ring?
The jet was rebuilt about 5 years ago with limited use till last year. I got remarried and the new
wife loves the lake and boat ;D
Thank you.

Tom, what's involved in changing the impeller? Will I have to replace the wear ring to fit it properly or is it just a change out?
I'm not to worried about having enough tools to do the job. What I AM worried about is having
to little knowledge to keep from screwing something up :banghead:
What brand impeller would you recommend and what would the price be delivered to 16652 central PA?
I'm also interested in a place diverter for the 12JE. How do you control them? Where does the control wind up on the interior? Floor, by the throttle on the side or what? I don't have a foot throttle.
All I can say is thank god for this forum! A little knowledge is dangerous, but with your help things don't seem such a big deal anymore.
Thank you! ;D

i wouldnt change the impeller unless it looks bad or you want to take out dings or sharpen it the berk aluminum in my boat is good at about 600 hp what makes you think you need a new impeller im sorry how much hp and rpm are you running?
-
go with the manuel place diverter mount handle on floor with the manual you always know where the jet is
-
Do you have a picture of the floor mount for the place diverter control?
To the other post the HP is about 450, RPMs 5100-5200 depending on load and wind direction :)
I just thought after 31 years it may be getting tired. I know it needs trimmed up at the very least.
I thought I would change the impeller if I put on a place diverter.
-
if its never been apart in 31 years i would say rebuild time you dont have to pull the pump to put the diverter on i dont have a photo but check placediverteron google youl easily find one jim brock has new or used give him a call 818-890-1867 hell help with any or all of the above hes awesome

He said it was rebuilt 5 years ago, but has the original impeller.
IMO, I would get your impeller blueprinted. I got mine done at MPD and the performance was huge. Unless your impeller is completely focked up, they can usually bp it and make it better than new.

Electro sorry been really busy just caught this .. Impeller change is a very simple op , may or may not need to swap ou the WR (thats easy too) We only sell A/T Dom/Legend Impellers price is in a PM as far as the work goes Josh or I will "walk you thru any of this you feel confortable with Re the Place Diverter IMO no Jet (with the exception of some race boats ) should be without "trim" ,best bang for your buck ,never had a performance complaint in thousands of sales. re Floor vs Hyd the percentage runs about 60/40 (more mans) shift and throttle control type doesnt Matter I personally like the manuals for lake boats (faster reacting) Heres a Floor control install (Josh's is polished and NOT typical) but the only one I could find this AM Floor controls are easy to shift on the fly the do cause a few stubbed toes ,hydraulics control with a toggle or steering wheel mount switch etc Hope this helps Tom

Damn Josh, as if that little hot rod wasn't cool enough....the Nos bottle adds to the effect.

Thank you for all the input. I'm on two weeks vacation starting yesterday so there will be no taking the boat down now. You guys don't disapear around the end of September do you?
I'll probably do the changes then. I don't want to risk down time in the season.
I will be doing the place diverter and pulling the impeller for inspection. If it just has a few nicks
are you guys saying just trim it up a bit?
I really appreciate you guys being there!
