im new to jet boats and i bought a 77 sanger super jet and it has a berkeley 12jb-a .... all the info i see on here talks about 12 jc pumps.. is mine bad?

The b is in reference to the split bowl. The c isnt a split but vanes go out farther for better flow. I have a modified c thats split now.

I think my pump has a C bowl..... I cant add a droop snoot to mine...there is no where to bolt anything up to it... please help

if you have a c bowl , then you cant add a droop to it unless you have it modified or do it yourself. been told not worth it.

hey mobboss, do other bowls interchange with berk pumps... that way all i need to do is find a split bowl?

not yet, going to try to do the droop and diverter at the same time

bowls arnt cheep not that a place diverter is either but you may just want to put a place direrter on and see if your happy. what are you trying to accomplish anyway if you mind me asking???

this is good advise

yah well your buddy may have great intentions but is gonna cost you alot of money and probable wont be necessary . boats are not cheep.

i bought a 77 sanger super jet with berk 12-jb-a pump and a chev 454... its 18 ft and no interior... its a project...

You need to post some pics of the pump and the tag if it still has one.  That way we can at least tell you what you have and what you should do next.

Who told you it was a 12jb?

the pump was apart

IMHO unless you building a 500 +hp motor the droop will be unnecessary. I would try the Diverter and see what she does, that's a nice little boat.

Put it together then see what she needs. There is nothing at all wrong with the JB pump suction BTW, it was the predecessor of the JC and JG pump. They are actually a bit thicker in the construction in the area of the packing, otherwise identical.

If you are going to build 500+HP, lose the three point mounts, they are not strong enough IMHO to be safe. Go four point or buy a rail kit. Several times stronger.

thank you... i plan on changing to a four point system... i have it all striped down now getting ready to have it capped and re painted... the guy i got it from started replacing the floor so that is next then paint.. ive been reading super jets capping process, that sounds like a lot of work though..
