even if he was five feet off the dock nobody would say anything because it's a Schiada...[emoji23]

Lol. Believe it or not I usually was less then 90 I’m guessing by Fox’s. I like straight open areas for safe keeping but at times we all get a bit jiggy [emoji38]

That was badass, anyone else see the fish jump at 2:40 just to the left of the boat, it's a big fish if you can see it on camera while running 90mph.

Scarred me on that other video. I barley turned. I also almost hit a bird.

2000HP cats run 170+ with M8's /6's

I dont see anything that leads me to believe he can't pull a bigger prop (and still plane fine because of the trans)

I would not take a bet he couldn't run with a large engine cat if setup for it.

Alexis been putting big cats on the trailer at naci for years. He is THE alpha predator on that lake and most others.

even theoretically faster boats in top speed cant touch it through the middle and that's where the most fun is

The camera sucks DAve. It only screws up in my boat, I think it gets RF from the big giant ignition. See all the garble. I was gonna ask your thoughts. I’ll call you. Scary to run big twins unless I can see way out ahead, just dangerous as it is much easier for them to sustain speeds and I have less room for error[emoji1303]

I agree, something doesn't look right with visual speed and gps stated speed.

This is the exact reason I have never once since 2010 posted any speed. Nor do i have a Speedo in the boat, I got a new Garmin camera and simply downloaded it and edited to shorten the video. My GoPro works the best. Better quality. Surely we can setup court with a radar gun as I have done but what’s the gift[emoji6]

I think you have to be 23 ft to run at LOTO but yeah
I was going to take my 20.8 post big block upgrade but its too short and I recall 21 was as well.

On a river with flat water - The only thing thats gonna run with that is a full on race boat like a K boat, or big cat - which you get in parker time to time.

using those kind of boats are pain in the ass - try a full trip up and down the river with zoomies - it's really not fun.

This thing is jet pack strapped to an easy chair - it idles like a kitten and has a bulletproof drivetrain that can take the power its being fed.

You can take kids tubing on this thing all day - and idle it eternally its manners are perfect.

Its just extraordinary on every level and I laugh like a kid every time Ive ever seen it.

No interest. I built it for me and we use it for several great times. Lotto is big boat land. But you know me, not really interested as it makes us no extra $ and the ego don’t really care. Someone else can drive and I’ll build a rocket. Too many good folks gone, call me a woos! I’m just afraid of what I know I can build in all honesty!

Its simply the wickedest boat around- maybe ever.

110% badass.

The boat I would watch out for is my dads old 21, I drive it for Andrew k the other day and it reminded me of what a really fast 21 was like with a carbureted TT Motor! That boat was amazing back then and now! Wow!

The boat is beautiful and very impressive, especially how it went through some wakes at speed and was so stable.
Nice job.

Anyway, think about this, a nice injected twin turbo motor in a 21 with decent gears goes plus 115 and I know a couple that go better then that. Only a couple. Those are 540-565 gasoline motors making 10-15 psi on kill mode at best. Mine is no rocket science, is way bigger in inches, head flow and compressed air capacity plus I run straight 98% alcohol when I’m on big power settings. So 40 psi will pull any gear really any rpm as the prop acts like a torque converter in a way with slip. If you notice the way I drive, I slowly input the power to keep hooked up, THAT is the secret, stabbing these heavy cruisers digs a hole. Big boost, big gear or final drive ratio however you get it and prop along with driving technique helps attain speeds.
The boat handles great plus 100 and never makes me feel uncomfortable. What is uncomfortable is discovering that the driving sensation at 115 plus or higher really feels the same and that’s scarry, it actually gets quiet to the ear up there! Actually lees turbo boat has a similar phenomena at high speeds. Bottom line is they are most fun in general at 100 and that’s really enough to have an amazing time. One of our true 1000hp efi supercharged engines gets there and that’s a great package. Anyway. I had fun. And it was nice to see 50 plus SCHIADAs that was neat. [emoji1303]

I want a down pedal in my boat.


Are they giving those things out now? I need one too, I hate that electric cav plate BS.

Half of the time I dont think its working, and the other half of the time I have no clue where its at. I'm tempted to just set it in the middle and disconnect the switch.

Check out the motor, if they are correct they are not that bad. [emoji16]

yea I do need to dig into it. I plan to tear it down this winter.

Any clue off hand (a guess is totally fine) regarding how much throw the motor should have?

Usually $659 ish depending on which one and how it’s prepped

I believe they have around 3”-4” of throw on the motor itself full stroke. When it’s hooked up to your plate pushrod, you won’t even come close to using that much stroke to cycle your plates up and down.

Thats assuming you have the same linear actuator most have.

Alexi @BoostPower can probably be more precise on those numbers than I can. He also gave the actuator on my 20 a new life when it was in need.

Really depends on the control arm length and the geometry with the turn buckles as well as the length of the plates. It’s all of it plus driver preference.[emoji1303]

Care to give a few more details on the drive line setup, ( v drive gears, prop size, type , shaft angle etc). That thing seems so calm at 100 plus, my 21 Howard is a white knuckle ride at 110.

Currently 62 gear, od 3rd gear 11.3/4 16 prop and the angle is less then 12 degrees it’s been a bit I’ll need to look. External rudder with Hyd steering. Boat is heavy and rides fairly flat. Very drivable at high speeds as it has the power to keep the plates down and enough rocker to keep the boat riding proper. I like the HOWARD [emoji1303]

Thanks, I figured with the power you had, you could keep it trimmed in tighter than I can with my Howard.

Yes and I can introduce a bit more rocker with a longer plate. This boat is heavier then it looks so it really works well. Just depends on the net goal how they are set up.

Quick question: does the front deck push the wind up/over your head or are you taking that 130 mph blast full on?

They react very quickly and are priced for the schiada market at around 5K. You will still need to buy a pedal not included.
This is the same one that is in the 20' k boats
Haha...the Schiada market. Who makes it?

It’s fine to around 105 after that it should have a Sheild. It remember I
Blipped it. Normal driving is much slower

Made out of Idaho. Need a splined top shaft on vdrive and room for the pump to mount right there. I dont have any pics right now (working out of town) but can get some and the guys contact info. He also makes a cavitation assembly(turnbuckles, bus bar ect) that is way over the top!!

I can attest to the quality and reliability of Alexi’s product. He builds some badass reliable motors that just purr right along. I have one in my Hallett 210....[emoji1303]

Is that a stepper motor inline? (Never seen that before, but pretty clever!)

RD

Looks like a hydraulic actuator valve that chases the cylinder. Kinda like how saginaw or brazil steering works.

Sure, its an overdrive 3rd planetary--custom made in 2010. I had it out for a bit and really only use it when I run alky. On gas settings it puts the net ratio a bit to high for the lower power setting. Not really a popular item but at the time 62 was the biggest gear I could get in the box. Now we have a billet gear box that accepts an unlimited value.
