    Default Jet ID Help

    Have a question that I was hoping to get confirmation on in regards to what jet my parents neighbor has! For a few years now my parents neighbor has been wanting to get a jetovator/place diverter for his boat and until yesterday I hadn't had an opportunity to get a good look at his boat to make sure that is indeed what he has for a jet. He has been insistent that he has a JE pump but I just went over there to check it out for myself and it doesn't look to be a JE but instead a JB! Even though it has the bolt on nozzle like the JE/JG models and the reverse bucket arm is on the same side as the JE, the control cables aren't on the bottom of the jet like a JE.

    Done some google searching for good pics of a stock JB pump but haven't found much so was hoping that one of you could let me know, found a great deal finally on a JE place diverter on here but am now afraid that it won't work with what he's got! Also snapped a pic of the ID tag off of the jet which looks to be a JB (couldn't tell when I was taking the pic due to the barn being extremely dark but the camera picked it up pretty good).

    Thanks in advance, you guys have been great when it comes to helping me in the past and I appreciate it a ton!

    Yup, not an "E". Looks like a early "B" suction with a "G" bowl with the early tiller arm assembly.

    Good find .... your Jet looks to be a mid seventies 12 JB as said above . I would say it looks like an early B bowl which is a forerunner to the G , the B can be made to work well , the ID plate indicates it originally came equipt with an A impeller and although hard to read the end of the number looks faintly like an SS stamp suggesting to me it could have or may have a stainless impeller Tom

    looks to me like the plate says JC, and that's obviously not a C bowl. while it might be a b bowl, it could easily be a g. with an old hokey bowl extension/nozzle combination.
    a place diverter would be a big step up for that thing. I'd get a mini droop at the same time, which will bolt right up to that bowl, so there's a good new socket for the nozzle assembly to set in. sockets on old extensions, like that thing, wear out.

    Thanks for the responses guys especially Tom for the indepth info on what it is and could be! I'll have to get over to their place again and see if the last 2 letters are indeed SS, you have me curious now! Just wish I'd known this for the last few years because I've passed on 3 awesome deals on jetovators/place diverters that would have worked with it!

    So, how can I tell if the bowl is an early "B" and not a "G"? Any casting numbers or measurements to confirm either?

    As for bp298, where are you seeing the "C" on that plate because I must be missing it!

    Nameplate looks like a JB with a SS impeller to me. I wouldn't concern myself with what bowl it is. It is a split bowl and any JB or JG component will work flawless on it. I have a JB in my boat. As Tom said, JB can made to work good with some bowl cleanup. If it is a mild build, it is fine how it is.

    Default Easy ID!

    The oil fill plugs on the split "B" s are about 4" apart. The split "G" s plugs are right around 7" apart.

    I didn't see his giant blowup pics. the plate in the smaller pic you posted "looked" like a c. but I'm old and have glaucoma .

    better than going by an old tag would be climbing under the boat, looking at the impeller to see if it's ss or something else.

    a jetovator is a pos. good for museums. a place diverter would definitely be an upgrade.

    Now that was what I'm after, and it appears from the pics at least that it would indeed be a G bowl if those measurements holds true I guess! Thanks for the info!

    Ha ha ha, it's all good my friend! Thought you had seen the blown up pic that Tom posted since you commented after him but looked just now and saw the time difference and it all makes sense now!! ahhaha Just wanted to make sure I wasn't missing something that everyone else was seeing! And yes, I went back over to my parents place today to tell him that we could look under the boat through the intake to see if it was indeed a stainless impeller! I currently have a jetovator and am going to upgrade to a hydraulic place diverter here hopefully in the next month or so and trying to talk this guy into doing the same, place diverter is way nicer of a setup than what I currently have!

    Soo glad I went over to the guys place and looked at the jet for myself and equally happy that I posted up pics of it for you guys to assist me in figuring out exactly what this guy had!! I love this site and greatly appreciate you guys and your help!

    Maybe someone else will confirm the measurement idea, but at least I know it's either a JB or a JG bowl so I can find him what he needs!

    Also 1975sleekcraft, do you have a place diverter and/or droop on your JB? Got any pics of the setup that you could post up for me?

    Early split bowls were commonly found on suction housings with the 12J "B" stampings. Heck..you could find a 12J "C" suction with a "G" bowl on it. Kinda like a SBC....lots of parts interchange.
