Can some one bring me up to speed on what a split bowl looks like, what "split bowl" means and maybe even post some pictures of a split and non split bowl. I am looking into buying a berkeley to convert my schiada and lose the drake pump and I need to know. Thanks!

I'm no expert but as far as i know the advantage of a split bowl is to allow you to bolt on things like wedge, snoops, droops, etc.
Here's a pic of my bowl which is a non split bowl.

And here is a pic i found of a split bowl

Thats only half of it but you get the idea i think.
I'm sure there are other advantages.

Thanks Shaun, I am looking for the internal differences, IE flow and whatever other characteritics that make the JG a better bowl....

I know I will catch shit for this by a few board members.... but oh well...
JC - One Piece bowl and has the longest vanes on the exit side = straighter water flow
JG - Split bowl and has shorter vanes then a JC
JB - Split bowl and has even shorter vanes then a JG
The problem as stated before, you can't add a droop/wedge to a JC, that is why a JG (split bowl) is the desired bowl.
The best of both worlds is a converted JC to JG bowl. You get the split bowl benefits of adding a droop/wedge, and the JC bowl benefits of longer/straighter exit vanes.
Here is my converted bowl

While were on this topic, are the bowl powder coated or painted usually? Mine look beat and i want the glossy look like the one in your pics.
Also when you say converted do you mean that you had your JC bowl modified or you just swaped bowls? I figured i had to buy a new bowl.

Either way, paint or powder coated. I had mine powder coated blue to match the boat, but when white, I think a lot of people paint them.
To convert a JC to JG, my pump guy cuts the end off the bowl, but not the vanes. Then he machines a collar that is welded to the bowl and starts to shape/weld the vanes to the collar as well. The finished product is what the first photos of my bowl look like. Its a pretty complicated/long job.... lots of welding (7-8 hours of labor) but in the end its worth it. Some people don't think so, but guys like Jeff Benett (bottom guru) has even told me thats the best bowl to have.... I guess it comes down to personal opinion. For one, I went that route because it was the least expensive, even though some people think I have this open check book and pay top dollar for everything....

I'm going to assume you had MPD do it? What'd it run ya? Also what about the other end of the bowl, did they convert it too?

You are assuming correct. It costs $375 for the conversion. The front of the JC/JG/JB and any other Berkeley bowl are all the same. I did have Jack do some work to the front... and Chet will be happy to learn over the winter, I have MPD add a stuffer to my bowl when I switched to a stainless impeller.
Justin, no prob.

One more piece to add, if you don't already have the JC to start with, you might want to look at a JI (Not sure if CP is still poping these out). They have slightly longer vanes than the G, and if you have to buy one to start anyways, might as well just buy the longer vaned model (though not as long as a converted C)
As an asside, there was a nice Berk/BBC combo Spectra 20 in the trader last week. The price was a tad high, but considering the season...
