    Default Crap

    I've been messing around with different setups this winter trying to get
    the bow to come up some. Boat rides nice, but really really flat. Full
    diverter and 7 degrees of wedge and the bow is still planted. It runs
    pretty good despite the way it is riding (80 mph on the motor, 87 mph on
    a 150 shot) but it I know it can do better. A couple passes on video

    You can see how flat it's riding, particularly in the second pass with a lot
    of diverter.

    Debated on whether or not to go after the bottom. Pulled the back
    seat out to do a little restaple/maintenance and found the damage
    below. My decision has been made for me. Motor is out, fuel tanks
    drained, and seats pulled.

    Bottom of boat



    Inside



    About the middle of last season we were floating down stream and the
    water was low. I had tunked a rock and later when I got it out of the
    water I checked the damage from underneath. I saw the gouge in the
    first photo, but didn't realize what it had done on the inside as it was
    under the motor and all but impossible to see. Always had a little leak
    but I chalked it up to being a boat and figured a bad RTV seal around
    the pump, leaky packing seal, header weap etc. It wasn't bad at all so
    not real concerned, but obviously now that I know what's going on, I'm
    gonna fix it.

    I've got 1/4" of hook on the left side of the intake, about 1/8" on the
    right. As long as I'm fixing the other, I might as well do this too. It's about
    6" long on both sides. I'm not going to make the mistake I did on the Kachina.
    I'll only work from the middle out to the second strake and stop there regardless
    of whether it rides right or not after the work.

    Thumbs up

    Tail's a little high but the boat looks right on the water
    What R's you turning?
    PS...too bad about the bottom, it's always something ain't it.

    It's not terrible, but with all that up angle (between diverter and wedging) that thing should be flying the nose big time and it isn't. Not that I'm looking for that in particular, but I think if I could adjust that attitude just a little, it might pick up some speed. RPMs are 5200-5300 on the motor and 5500-5600 on the juice.

    what type of ride plate set up are you using sometimes they can bow and create a hook also and also make sure that its set up correctly. Another possibility would be to move the engine back depending on where it is now that would generate more lift also.

    attitude is fine. gullwings seem like they're more sensitive to plate angle changes than nozzle angle changes.

    What are the specs on the shoe that you are running and what was the ride plate angle?

    I'm sure you'll be fine going to the second strake, that's what was done to mine. Perfect time to fix that boo boo, I know it'll come out great.

    Dan, are you running a back cut shoe? If so switch to a tapered. While you are doing the bottom send your intake to Duane at Hi Tech and have him make a tapered shoe for you. That will definately raise the bow and air it out. I talked to him last week about doing mine, said he could have it turned around pretty quick.
    Sorry to hear about the bottom but this gives you a chance to make some changes that you probably wouldn't have done otherwise. When you are done that thing should be in the 90's easily.

    I know have'n to much wedge and diverter can push the ass of the boat down to much in the water and make hell of a drag. that sucks about your floor... get it fixed and lets get back to the lake..

    DAmn Danny, that sucks but since it's still cold outside, you've got lots of time to fix it up.

    I've tried quite a number of different setups. I've run it with down wedge, no wedge and up wedge. I have a 2, 3 and 4 degree and have run them separately and in conjunction with the others. Last test I was running a 3 and 4 degree up trying to get the bow to carry. I know that's a pretty absurd amount of wedging, but the funny thing is.......I got no more bow lift than I did with just the 4 in it so I went back to the 4 degree.

    Rideplate is up as high as it can go and is at 4.5 degrees. In the past I've run the plate from flat all the way up to where it is now in 1-2 degree increments. I've put a straight edge on the plate and no sign of any warpage or hook. It has stiffners on it too.

    The shoe is a backcut. Not sure how much backcut though. I've run it 1/8" above keel and right now it's shimmed even the keel. I'd try a tapered, but would rather find one to borrow before laying down the cash not knowing if it would help or not.

    Motor is back as far as it can go. I'm running a jetaway so it is quite a bit farther forward than 19's without. Not looking to get rid of the jetaway though. I know there are 19's out there with jetaways and motor forward that run drier than mine does.

    In short all the setup stuff I've tried, this has been the best to date. Rideplate up 4.5 degrees, Wedge 4 degrees up, backcut shoe even with keel, loader 1/8" up in the hole, diverter adjusted for about 4'-5' rooster.

    Now I don't know a lot about them so all I have to go off of is what Duane told me. He said that to get it right it needs to be made to fit your boat, they are not universal, so you couldn't use someone elses. Give him a shout and see what he says. He did tell me that it would raise the bow.

    do you want the nose higher or more boat out of the water ? If more boat out of the water try a 2* back-cut if you don't have one in already.

    A starting baseline with the bc shoe would be 3* on the plate and 4* or 5* on the nozzel. That's conservative and then you can air it out from there. 1* at a time. don't exceed 2* between the two.

    99 mph w/flat shoe 4* on plate 5* on nozzle:


    Old times, 92 mph w/ 2* back cut and 3* plate 4* nozzle:



    This is River Dad's boat he was trying to get his nose down, are you looking to get yours up like this? :
