I have a 12 jc with a place diverter on it. But I want to go to a split bowl. Do I have to get a hole new pump or do they make a split bowl convertion for my pump. Thank you.

Bowls are interchangeable. I have a JC as well but got an American Turbine split bowl from JBP a couple years ago. The cool thing about AMT bowls is that in the area where you'd normally put a stuffer, AMT has a machined area there. AMT makes impellers specifically for these bowls that has a wear ring skirt on the backside of the impeller that rides in that machined area, in effect acting like a built in stuffer.

Here's a vid of my boat running with an AMT split bowl and an Aggressor droop.

I am also, doing the same thing with a JC pump. Any help and and info would be great. I am also installing a droop snoot to.

What kind of bowl are you putting on (make)?

Dominator split bowl is what I have. Ive been told that it is no problem to put onto my berk.

Not at all. Now is it the old style bowl where the back bearing water lubricates, or the new one that uses the grease zerk on the hub of the bowl where the droop goes?

OK then more than likely it's one that water lubricates.

Should be a direct swap. If the bowl is used I would recommend changing out the bowl bushings and shaft seals.

I'm sure Tom at Jet Boat Performance can help. 805-466-4719

We have new Bowls at SCJB  prices , some used bowls (may need some work) and "converted" bowls that have been machined and reworked Tom
 

Tom you do have stud kits and gaskets etc to install the bowl correct?

Absolutley !!
