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.

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.

So it would seem Ray...........so it would seem.

Ouch !

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..

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.

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? :
