Excellant pump. I read a story once where they wrote that the JC's bowl is the best flowing bowl Berkeley ever made.

I've had NO PROBLEMS with mine; of course, I haven't had the boat in the water yet.  :P

one of the downsides to the JC is that it is not a split bowl...so running a droop is out of the question, but i think ya can still run a diverter....someone correct me if i am wrong, i am lacking JC knowledge skillz

also, thats why you will see JB/JG pumps on ebay goin for more. they are the more desired pump

on the flip side, there is a possibility to convert a JC to a split bowl


just something to keep in mind when buyin  ;D

Can someone explain the split bowl: purpose, advantages, etc.

this is a split bowl....

if you notice, the split bowl is 2 pieces, making it possible to mount wedges, droop snoots, etc. the 12jc is static and doesnt accomedate these options.

Heres another split bowl.

(https://www.socaljetboats.com/proxy.php?request=http%3A%2F%2Fi29.photobucket.com%2Falbums%2Fc290%2Fbeerjet%2Fnewpump002.jpg&hash=44c2dc9d758e9b215d21641422d4250fae0b0253)

You can see on mine I have the droop bolted between the bowl and diverter . You can also add wedges between the bowl and the droop to further fine tune your set up

(https://www.socaljetboats.com/proxy.php?request=http%3A%2F%2Fi29.photobucket.com%2Falbums%2Fc290%2Fbeerjet%2FPicture004.jpg&hash=7b369ca6e4120f8d1718101cee9fc2924f298576)

A diverter can be bolted to a JC bowl thus eleiminating most of the hassle of running and experamenting with all these wedges and droops and snoots and extension and so on and so on . On a recreational boat that will only see lake and river weekend conditions , a diverter bolted to a JC bowl will be just fine since the JC bowl veins are a longer , straighter shot to the end of it's path (being the end of your nozzle) the JC bowl flows very well . With a Place Diverter you will also have a lot of adjustability and not have to deal with trying to figure out how to even get a baseline for all the split bowl gear . With a split bowl there is a ton of adjustability and when you couple it a shoe and ride plate , you can spend days on top of days trying to get all this adjustability to work correctly . If you ask RWYATTB how fast a boat with all this adjustabilitly that is not set-up just right or even close will pitch you into the water . Its a double edge sword and in 90% of boats the JC is just fine . If there is any incorrect statement or info or something I left out , Please feel free to correct me .

I noticed on The Chaz's boat yesterday that he has a one piece bowl turned 90 degree's to allow a jetovater to be installed on it. Kind of a cool concept...

if you not looking to set any speed records or looking for cool factor you dont need a ride plate. its like beerjet said it gets ugly when they are NOT set up rite

Could you go into that ugly part a little bit more, what happens if it's not set up right? On a pure guess, how much MPH do you think it would be possible to gain with a shoe and a ride plate?   ???  Some day I'd like to add a ride plate and shoe to my Rogers.

i'm no expert but i can give you my personal experience. out at ming my ride plate was set with 0 degree and my firtst practice on friday night 70 or so mph i let off getting set for the corner and it hooked right and almost pitched my azz out. so i raised it up 2 degrees and it got better but still twitchy when i let off.

out to parker same 2 deg rougher water getting set for turn one hooked right at about 60 and put me in the next lane. so i raised it up another 1.5 and it got better but i still cant get off the gas without pedling it. so i think i need another .5 up.

as for mph gain i dont know because of the speed limit, hell i dont even know how fast the damn boat is.
hope this helps.

How do you figure out what degree it's at? Degree's as compared to the bottom of the hull? Thanks Ralph!
