They posted this in the V-drive section and even I know asking a V Driver how the set on a jet looks is like asking a straight guy for fashion opinions. Even if they know the answer they'd be too embarassed to give it in front of their friends. Anyone have any thoughts on how this boat is running?

Steve, as requested...

Here are the pics that I have for you to have the experts analyze and advise maybe why you took a dive last Sunday...

I can only describe what I saw from the shoreline as you went by from left to right...Tony and I were both commenting on how much air was under the boat...you went by and as you took the corner a little hot, it appeared that just before I lost sight of you around the hill that the boat did a chime and last thing I saw was your arms flailing and the boat looked like it was flipping over barrel roll. I lost sight because of the hill but yelled to everyone that I thought for sure you got wet...You did...

Hope these help...

We need you to stay safe...

Looks to me like that boat is running good. A boat designed to go around in circles is going to ride different on the hull when compared to a boat designed to run in a straight line. That boat looks like its setup for a straight line.

Its kind of a vague post over there in v-drives. It's not clear who or what you're asking.

If I'm reading this right, and you took the corner hot with all that up diverter, that might be cause for the barrel roll. Over all the ride looks real good, but I don't think I'd throw it into a corner with the bow riding that high and boat that loose. Running all that rooster won't help your handling, or even speed. Typically a 3-5 foot tail is about perfect. Anything more than that is (pardon the pun) showboating. On a tight corner I'll drop the diverter all the way, then trim back up once the corner has been negotiated.

Just an opinion

That boat looks like it riding real nice.
I could see the driver easily getting wet taking a turn too hot.

I agree has nice air under the hull and just the rear is wet just what you want going straight but not trying to manuver a turn.

78 eliminator Bubble deck
delta pad, ride plate, 2 deg tapered shoe, droop with 4 deg. wedge.
I understand where I went wrong, I believe it was a combination of a few things.
When they speak of turning It was just a slight turn to the right,( not an aggressive turn) I was having a friend take a pic of the rooster tail so the guy who set the pump up could read the feathering of the tail.
As I was letting the tail down the boat freed up more raising the ass end even more and the combination of speed, the slight turn to the right, and riding on the delta pad, current of the water in the river and possibly a small roller slid the ass around loosing suction and I went left the boat went right.
The boat never barrel rolled, and the rooster was down at the time of the slight turn to the right. I agree with you all never turn at speed, (be kind) lesson learned.
My question is do I need the droop, I don't think I need the 4 deg. wedge, or will a straight snoot work. I also realize every boat is different.
Just looking for some sound advice from some axperts.

Reason for post

Steve is my buddy, new to the higher speed stuff and asked if I could post the pictures so Greg Shoemaker can see them...I think Steve and Greg have been talking/working together on this set-up on a long distance relationship and this was the best way to show what was going on...

The v-drive vs. jet family feud is always fun to stir up !!

Sounds like you got kinda lucky. I would be curious to see how the boat rides with a bit less diverter. I honestly don't know anything about delta pads and how they ride or handle, but as most of us stated earlier.........over all the ride looks pretty darned good (that's coming from a non-delta semi-v owner).

I would say a droop should help you get the ass end up more and the boat will ride a little more level. You will be able to ditch the wedge and with the droop you should not have to have the diverter up that high to lift the nose. It sounds to me like when you put the diverter down you slapped the nose and it hooked. It happens. and you learned a valuble lesson. and this is the reason that we wear life jackets when making passes. Also why it is good to have other boats around. I am glad you are ok. With the diverter up that high, you are driving the tail to get the nose to lift therby shaving speed by directing the thrust downward.

I loved the conversion kit Dave. Thanks.
When I was putting the diverter down I always put it down slowly, The ride after the diverter was down was like no other ride I had felt with this boat, Free and light as a feather. (sweet spot) With the stock motor i never had any problems in the 3 yrs on this boat. However when putting the new motor in, Big H.P = change. I need to do a lot of research on it's set up. any help is appreciated.

I read this a couple of days ago and I've been thinking about it ever since. I have never heard of "reading the feathering of the tail." Can anyone explain what that means and what's the purpose of it? As I said, I have never heard of that term before.

One of the thing I look for when hardwaring a boat is to make sure it has a very solid rooster tail. This will tell you if it is loading the pump properly. a choppy roost will give you an idea how it's being loaded. With this observation and the input from the driver you can generally come up with a direction to go on the next pass. This is how we used to do it in the old days without the help of a computer. My how things have changed.

Steve (Katchenup) we were all relieved and very happy to hear you didnt get hurt and that the boat is OK ,seeing/hearing of these things ,Heatseekers Unc, Little Rick a few months back and Tony Scarlotta's horiffic wreck always has a "sobering effect" and reminds us all of how little seperation there can be between a thrill ride and disaster in this sport we all love . Please "Vest up" everyone and be safe ! Tom,Rhonda and Josh

ps The Boat looks Good !

pss Your kill switch is on the way ;) !

Greg,
Real long time no talk! Thanks for the response and if I didn't way back when, thanks for the advice on cam choice on my rebuild a few years ago.

I would assume water conditions are a factor in whether or not the roost is choppy? I would then assume that you would need to have pictures of the roost in fairly flat conditions in order to better assess the set-up? If I'm off base here, please correct as I am very curious....it's in my nature :p
Do you have any pictures that can show the differences?

Here's a pic of my boat and roost-


would it be considered choppy given the flat water we're in? btw, that's katchenup riding shotgun.

here's another on a different day, different water-


another BTW, I remember those old days very well! the first time I met you was at Chowchilla in '82, I think it was.

Jeeze, how old are you Cas?
as Hustler said, not quite as old as you :D

I'm also still thinking about this whole reading the feathering of the tail thing. At the track under relatively controlled conditions and someone looking to cut a 1/10 in the 70's makes some sense. Someone running on a river/lake with varying conditions and turns making wot runs to get a picture of a roost makes none.....to me.
will the roost show too much shoe depth? too much loader? both of those things will load the pump but be hell on shut down.

edit- apparently it was taken as a personal attack.....not the case
