    Default Adding steering rudder to Berk. with Place Diverter

    How to you remove the lower pivot shaft to replace it with the one supplied with the rudder. I know you have to remove the shaft bolt, then shaft has to be driven or pressed into snoot or driven or pressed out bottom?

    Not sure how to reach it to get it out the bottom.

    Anybody done this before? Need some advice.

    Thanks.

    if you move the deverter left or right ( i think left) you should see a allen nut you unscrew. then the pivot pin and the nylar bushing come out.. Replace the bushing if it is worn or damaged.

    Ill try to find a pic of mine.

    2X what he said

    All you do is tap it in and out,as long as you get the bolt out.
    I find it easier to do when it is off the pump.

    I have mine apart now,I'm not sure what hull you have,but I have been told by greg shoemaker himself to "take that thing and junk it".
    I was told this by almost everyone I talked to about the rudder.If your looking to get more speed out of the boat don't run it.
    Also I don't think there is a plus to the thing,just 100 buck I could have not spent...But ain't in all

    I'd have to agree. Just leave the thing off. Save the money for something else. There are tons of pump pictures here the board. On 95% of them you won't see a rudder.. They don't help much, even with slow speed handling.

    Here's mine.

    I am actually adding one to help with slow speed maneuvering, been playing with v drives for a while and this is first jet I have driven without one and it steers so sloppy at slow speeds that I figured the lack of a rudder was the reason. Not worried about speed. Just need more butt slots and a sun shade in this ride.

    Had the allen head bolt out and gave it a couple of good taps, did not move so before I put any real force to it, figured I better get the straight skinny.

    Maybe some penetrating oil?

    Thanks

    Maybe I am wrong in my thinking?

    Seriously. If they helped you'd probably see a lot more people using them. It's not because we're (jetboaters) are too cheap to buy a new one. They simply don't work very well.

    Put the money you'll save towards a bimini or a big ass'd ice chest.

    Seems most folks are most concerned with an additional mph or two?

    This is my third jet boat and it is the only one without a rudder. Seems to handle worse than I remember the others did at slow speed. Maybe the hull design/combo? Maybe I got spoiled by the way a v drive steers at slow speeds, even with the engine off ?

    Not in my case. If they worked well, I would consider sacraficing a mph or two. They don't though.

    You might just be out of practice and/or spoiled by the superior low speed handling with the Vdrive.
    I don't even think about mine.

    Comparitively speaking, whenever driving a Vdrive, I'm more concerned with the whole no brakes, no reverse, and not being able to turn the boat around 180-360 degrees within it's own length.

    Advantage jet. That is one of the reasons I opted for it as a "family" boat.

    Since I have the rudder in hand, I am going to give it a try and see what happens. I had a 78 Taylor (stock 460 Ford and whatever Berkley pump came on them) and a 79 Mantra, (650 hp full roller BBC, modified Dominator with droop and diverter) both had the steering fins and handled much better at slow speeds. Gotta try it.

    Don't bother with the rudder. They don't work as well as you'd think, if at all. I spent the money and the first time I beached the boat it got all bent up. The pump will steer you just a good with or without. Buy some BLING for your boat.

    Since you already have it, give it a try. I had to remove the top pin in order to drive out the bottom one. No big deal really.

    Thumbs up

    I gotta say, I really liked the large rudder on my old Berk Jetovator set up and how it improved turning etc. Especially low speed steering
    when I changed over to the droop and Place diverter slow speed steering is ok but steering torque has increased significantly.

    I ran with out a rudder on my daycruiser and it handled like crap at the launch ramp. Put one on and it made a world of difference. My jet boat driving skills did not change, just the rudder! I think a lot depends on the boat you have. I would also think that your pump and motor setup would also have a lot to do with your boats slow speed controll.
