berk jf reverse cable set up ?

[Garett]

my new boat has a berk jf pump , are these decent? electric trim , well the reverse cable was un hooked , and the gate was all the way up, i dont know how this thing hooks up, i think im missin some hardwear ? or the lil connector plate , is hooked to the wrong part , ive been on berks website and others , no close ups of what im needing please help me , i want to restore my new ride , 87 baja 21 footer closed bow , alot diff lookin than my open bow was, more like a sliver , im also having seat probs i cant sit in the seat w/o hittin my leg on dash , the seat need to be lowered , but there is these fiberglass boxes that come out of the floor , that the seats sit on , what can i do this thing has no room at all!! and its a 21 footer i dont understand it? also the cable is not hooked to the foward and revere shifter ? how does this setup work ? and 1 more thing , it has indmar manifolds on it 455 , well where the bolts go , its split all the way through , on both sides all bolts , will this effect anything , are they supposed to be that way? will it leak? im really new to this , you guys helped my decide to get rid of the sbc so i got a new boat with a 455 has lotta little flaws , but id like to make nice , and im having a hard time finding a place that aint 2 hours away , thanks folks

anyone?

It's kinda tough when you ask so many questions all in one paragraph. If you use a separate paragraph or line(or thread) it would be easier. :)
"Mighty Thor" here has a JF pump and might already have pics of how the reverse cable connects. If not I might be able to get some. There's a JF equipped boat in my storage yard.
Exactly how the reverse cable connects to your shifter depends on whether it is a shifter or a shifter/throttle combo. Being that it is disconnected at each end makes me wonder about the condition of the cable or shifter. Must be a reason for someone to have done that. Can you move the cable easily by hand? The cable should connect using something like this availbale from Rex Marine, CP Performance or any other marine equipment supplier:

Many aluminum manifolds have the flange cut where the mounting bolts are. Allows for expansion/contraction when mounted to an iron head.
Can't help with the seat question. As is usually the case with boat mods, a little creativity and ingenuity will likely be required.

ok sorry bout all of them, it has a foot gas peddle and yes i can slide cable in and out by hand, but the cable comes out of the rear of boat and just hangs there nothing , and the linkage of the gate was all tight so it wouldnt come down , basically locked all the way up (open) i would like to see some pics of hardwear and how it connects , also at the controller ,i mite need a new foward and reverse controller? hard to get under there and look this thing is cramped to the max , was like a horse jockey used to own this thing;)

[Garett]

i seen that chart duane no help to me i need a pic on a boat if possible , i even have a selec manuel , no help there either

[GasGuzzler]

Traded Chevy for a Olds :hammerhea Maybe if you could post some pics of the jet(to see what mods have been made) you could get some help on it. And you can try to unbolt the seat, take it out, lay down to look at reverse hookup, and mount the seats where you want them.

That's a pretty scary looking connection between the steering extension and the tiller arm. You should consider using a "swivel steering connector" to make that connection. Take a look at the 4th item on the right hand side of This page in Rex Marine catalog (http://www.rexmar.com/page120.html) Using one of those in conjunction with a short spacer would be much safer.
Your reverse cable should also be attached with one nut above the arm and one below to secure it firmly. Adjustment for reverse gate operation should be done at the shifter.

Mine is set up the same way. I agree with using a swivel like old squirt says, but how do you get the steering cable to angle down where I put the arrow...?? :confused:

[Mighty Thor]

Here is a picture of my JF pump from a little different angle. Note the close clearance between the two bolt heads, I experienced some problems with these two hitting until I got a proper bolt put in place. I am still considering a possible alteration that gives a little more clearance, but this is what I have so far.

You can put a spacer between the swivel and the tiller. I believe Place also sells a tiller arm where the steering connection has been raised to accomodate the use of a droop.If you go to Place Diverter (http://www.placediverter.com) and look at their "elite" series diverter real closely, you can see how that part of the arm has been raised. You can also see it if you look closely at the slideshow in the upper left corner of the page.

[Mighty Thor]

Garret, in answer to your first question, are these systems worth it? The answer would have to be, depends. I did not have any trim adjustment on the boat before, and when I got the JF pump I ran it as non adjustable for a while till I finished the swap. The trim adjustment is a huge difference in being able to modify the action of the boat to match various conditions. So, in one way, yes, absolutely worth it. However, Reports are that other trim adjustment systems may be more adjustable or more performance oriented (place diverter, wedges etc) and then it becomes a question of use, cost and hull design. For me, the JF does everything I need for this "family fun toy tugger" and so I would not get much benefit out of adding other systems. For you, more speed, tunability, accessorizing or what ever may be more of a priority and some other, newer system may be appropriate. My advise, run what you have, study what they say here and decide if you need (or want) something else. You can always sell what you have now to get what you want later. As you have already discovered.

ok you guys are way cool , thats the pic i needed the one that ol squirt posted mine is just like that !! but its just hanging out of transum, looks like i need a bolt to hold it to the steering thing then the hardwear to mount on the lever, man i need to find out the part numbers of the stuff and where to order it? how does the cable hook to the shifter in boat ? sorry im clueless , ive read in my manuel that 2 fingers in gate should be close to neutral , and for the one fella , i wanted a 454 but a 455 should be better than the 350 i had i hope ;) and im not racing this thing just want a fun boat , i want to post a pic of what i am working with , can i email someone a pic , and post it for me? , and the seats finally there is a fiberglass box that comes outta my floor that the seat slides down onto , so how can i move it?

[Garett]

i have pics of mine now , the gate looks like the wrong 1 , not like the ones in pic , grrrrr , will someone post them for me , ill email em to ya ,

[Oldsquirt]

.....but its just hanging out of transum, looks like i need a bolt to hold it to the steering thing then the hardwear to mount on the lever, man i need to find out the part numbers of the stuff and where to order it?
If parts are missing, good luck. That pump style has been out of production for a loooooooong time. A good place to start might be CP Performance (http://www.cpperformance.com) They bought out the Berkeley name and rights to produce parts. CP's website has a blow-up of the pump like the one Duane posted a link to. There should also be a chart matching part #'s and descriptions to the numbered items in the illustration.
.....how does the cable hook to the shifter in boat ?
The shifter should have a lever on the inside of the hull for the cable to connect to. The connection is made by screwing one of the brass fittings I posted above onto the cable. The pin part of the fitting goes through a hole in the lever and is secured by a cotter pin. The position of the brass fitting on the cable threads allows for adjustment.

[Mighty Thor]

My "shifter" is a single handle outfit that works the throttle and the bucket with the same handle. Push it forward and it opens the throttle and lifts the reverse Gate. pull it straight up and it closes the throttle and drops the reverse gate. Pull it backwards and it leaves the gate closed and opens the throttle. If yours is the same set up then you will probably find a lever hanging down from the throttle mechanism with a hole in it. My cable has a threaded end and that has a 90 degree pivot that threads up and down the end for adjustment. You just put the piviot thru the hole in the shifter lever and secure with a cotterpin, OldSquirt's picture above shows three of the piviots. Since your setup is hanging loose it is possible that someone has replaced the throttle, or did you say it had a foot throttle? I can't remember. Anyhow, you are probably going to have to take some pictures before we can do more. If you send them to me I will post them for you and then I or someone can also show you how to do that here.

The "F" is a good pump and trim setup. Mine is now 27 years old and still works fine. There are some better performance oriented ways to go but they all seem to involve buying a split-bowl and then accessorizing to the tune of a LOT of dollars.
The trim makes a great deal of difference in the character of my 18'6" Taylor (in my avatar). It has seen some tuning work with DuaneHTP back in the 70's, is being upgraded these days (better loader, bronze impeller due to 454 HP mods). New the boat ran 72 on radar according to dad stock on 75HP of fun-gas.
Launches out of the hole very hard with the trim down and you can feel the acceleration cruizing when you trim up to lighten the nose and dry the hull some. I cannot run full trim up untill I am running smooth water above 4300 RPM, she'll porpose. More power and I can carry full up without bounce, tail about 10-12' high, nice and long. I can carry 3/4 (about halfway up) at any cruizing speed and it helps a lot reduce drag. Tail is only about 2-3' high then.
Check all your hinge points for small, flanged "nyliner" nylon bushings. Any missing, or with broken flanges are easy to replace, and inexpensive. Berk as well as any of the jet guys like DuaneHTP can get you however many you need (6 maximum).
I don't bother running the nylon-whatever o-ring nozzle seal in my "F". Last one came out about 1 weekend at the lake after I installed it, in pieces. Doesn't seem to hurt my speed any or acceleration. :clover:
As far as seat bases go, it's your boat. You can do anything you please to make it suit you, and I would. :chi:
If you mean split at the head-mating up bolts, yea, that is probably normal, "expansion cuts". The logs are water-cooled but, the ports that mate to the heads are not really "cooled" except by conduction via aluminum. The water jacket doesn't extend hardly at all toward the exhaust ports. If you mean at the bolts where it mates to the snails, no, not supposed to be split and would likely leak. :idea:
Good luck. The reverse gate setup is really very simple, especially under the boat side, although you may have to remove a seat to make it easier to deal with (may be why the "new" cable never got installed properly).
Also, there is an o-ring and a nylon/plastic spacer inside the 2-piece pass-thru seal where the cable passes through the hull. if any parts are missing, or in bad repair, leaks will happen there. Easy to fix tho. Takes 2 people tho to get the pass-thru loose as somebody has to hold a wrench on the nuts inside the engine bay while someone else unscrews the screws. I then seal the fittings on the hull with RTV.

Man, CP needs to do a little checking of what they put online. Their illustration, and specifically the reference numbers on the illustration, DO NOT MATCH the parts list below the illustration. However, if you look at the illustration that Duane linked to above, it appears to be the correct illustration to go with CP's chart.

[Mighty Thor]

That CP Performance diagram also shows the JE cable parts but not the JF parts and they are not the same. The plate on my JE was shorter than the one on the JF even though they were essentially the same as far as bends and function. The difference was for the slightly added length of the JF trim collar. I tried to use the JE ends cause they were already attached to my cable and they could not be made to work with the JF setup. I would call CP or whoever and make absolutely sure that any parts you are getting are the JF parts or at least verify that they are the same for both pumps.

[BigBlockBaja]

Garrett, do you need these? I dont have a F pump anymore. Yours free..

[Garett]

yes i mighty need them , im kinda bummed now , they havent made these for a long time , dude said good luck getting parts , now i feel like i bought a turd
lmao , my pics should be up soon thx to thor

[BigBlockBaja]

wanna see what i made my old f pump into?
From this piece of crap..

So down the road, you can have a really nice pump. Thats the nice thing about Berkeley....Interchangability.

[Oldsquirt]

Don't let yourself get bummed out by what I said. Figure out what you need and check with CP Performance. They just may be able to help you. I do know from threads here in years gone by that some of the JF-specific parts may no longer be available NEW.

[tahiti cowboy]

I might have some that you need Im not using thos style brackets caus I went to a split bowl ~droop~ and a diverter so Im not using it let me know

[Garett]

man , you guys are way cool , so helpful , if i get this turd going , ill be down to az , my sis lives in mesa , we have a cabin in flagstaff(familys) i cant wait till the pics are up i emailed them to thor, the gate is the wrong 1 , the cables i cant still get , if needed the impeller seems fine through the hand hole cover ...im hoping ill be ok

[BigBlockBaja]

Here Ya go Garett. Don't look to bad, your almost good to go.

thx man , see how my arm on reverse bucket looks diff, and the lil straight bracket for the hinge action is bent on both ends not straight i took the arm of the pump and reversed it so the long part on the bottom curves in towards pump not out , i need help;)

[BigBlockBaja]

Looks like you need the right reverse bucket. CP should have that, or someone on the boards might. That and some small hardware and your done..

[Oldsquirt]

This looks more like a JE reverse gate than a JF. Also, the "pivot arm" is connected to the flat strap, going to the reverse gate, upside down. It should be connected to the other end of the arm.
EDIT: Is this Garett's pump?

Garret, sorry I didn't get your pictures posted sooner, Kids band concert took priority and got home real late and had to be in Court early, by the time I got to your pictures today, they were already up. Anyhow, it really looks to me like you are only missing a couple of generic pieces on the pump end. You also have the wrong gate, but I think it could be made to work till you can track down the right one. Keep in mind that although the pump has not been made in a while, they are still being used and also modified so used parts are availabel and many parts are interchangeable with newer pumps and thus also available. Anyone who has or is going to put a "Place Diverter" on thier JF will probably have a used gate available. Post a Reverse spam in this forum asking for a JF reverse gate and see what you come up with. In the mean time, the clamp that holds the cable to the steering plate you have is a generic piece from virtually any Berkeley set up or you can fashion your own. It looks like a minature Conduit clamp. You probably have one just like it already screwed to the bottom of your bowl for the trim cable. The only other piece you seem to need is the threaded pivot we talked about above.
On the inside of the boat you could just fashion a simple lever system, forward for forward and up or back for reverse. There is no real neutral in these boats cause water is being pumped somewhere all the time and it becomes a question of how much throttle is applied to any particular gate location before something starts to move the boat in one direction or another.

[Garett]

thx thor i posted the spam hope i can get some of the peices i need soon

[Oldsquirt]

Garett, those cable clamps are available new from any marine supply and only cost a couple bucks. Check with RexMarine(http://www.rexmar.com ) or CPPerformance(http://www.cpperformance.com ). There's no reason to have to fabricate one of those.
CPPerformance should also have that pin. I think you also are in need of the clevis that threads onto the cable and connects to the reverse gate pivot arm. Don't see it in your pics.
Have you called CP yet to see if they have any of the stuff you need? I notice they still have the reverse gate listed in the online catalog.

[Garett]

yeah im gonna get the lil stuff new , but with just havin a baby n , winter gas bills commin , i have to wait on that gate its like 350. dollars , our gas bill this winter is projected to be like 600 a month , im bummed , i hope someone can find me a used 1 , with white paint its new;)

[Mighty Thor]

Tahiti Cowboy posted above that he went to a Diverter which usually means a place diverter that uses it's own gate, you should contact him and see what he has available. A word of caution, once you start collecting old jet boat parts they start to breed and before You know it they fill up the spaces you have. I started with just a Hondo hull and now have three Jetboat projects, four broken Jets, Two outboards for later trade and several disasembled engines. And this was just my first summer of boating. :mix:

[Garett]

ok , cowboy has 1 for me , i emailed him, thanks guys

[tahiti cowboy]

:idea: I know wye that looks so crazy its a old jetavater set up for a jf pump and I just happend to have the parts for it let me know

Dude, we already sold your parts to Garret, we just haven't let you in on the news yet. :D We are still negotiatin on your install work. We will let you know when you can go put this all together. :mix:
