nice attempts! you almost got it on one. My hopes are lost, I will need a TON of skill\practice to do it with a mild 701 and a less superior hull

 

[McDog]

I saw John get 2/3 with his today. I'm sure you will be flipping in no time if you will just finish the ski.

WAB came and rode with us this weekend. Sorry we didn't get to hang out more Andy, especially Saturday night. It would have been nice to grab a beer with you.
I enjoyed meeting you.

 

[ncbrock]

if you will just finish the ski.

this part made me laugh. Im actually really close. Its just the wetsanding\buffing takes a while. Once all that is finished. and all my parts are layed out for re-assembly I can probably tackle that in two days.

 

[Matt_E]

Very nice!

I should be spanked for being too lazy to look, but do you have trim on that?
Also, what motor?

 

[Waternut]

The first and second attempts looked really good. You just need to scavenge out the holds so you can get in/stay in them.

:spankme:

Jetworks 5 mil stroker 850cc billet ADA cylinder motor
Two new Blackjack 46's
Boyesen intake
Factory B pipe with a mod chamber
MSD Dual channel total loss
144 Mag pump with a 14/19 prop
Thrust EZ pull trim
-2 xft pole and bracket

That could be a bit discouraging to others who purchased these hulls thinking they could flip it with a 701, a TL 850cc stroker with a mag pump and trim in a BOB hull seems like it should damn near flip itself (on paper). There is a lot of technique to a flatwater flip!

 

[McDog]

I would say a pro can flip it with a 701. A no skilz old guy like myself needs more help. I'm probably relying on the motor way too much. I need some technique other than pulling the trim lever and the throttle at the same time. I've never even backflipped in the surf before this.

 

[Matt_E]

Your form is lacking. You would bring it around no problem if you:
1. Crouch down, off the back before take-off
2. Expand, stand up, kick out, and arch after take=off.

 

[Waternut]

I don't know about mcdog but I know every time I attempt a backflip right now, my form is the last thing on my mind. On our lake, it's rare to get a decent wave. When we do get a good wave, we then have to make sure some idiot isn't following right behind the boat making that wave. By the time you've decided it's a good wave and you have a clear landing zone, you're riding down the backside of the wave and trying to remember to grab the trim and the throttle. I'm sure we'll both get it before the summer is over but right now there's just too much going on.

 

[Matt_E]

If you do it a few times with form as the FIRST thing on your mind, it becomes more ingrained and automatic.
It took me a while (and I am not claiming I have it figured out), but repetition made the motions automatic.

I'll give that a shot... Maybe I can practice on setup wakes for a while when there aren't many boats out. I'll need to address my water ingress problems first though. The engine bogs and runs rough for a couple seconds every attempt so I'm guessing I'm ingesting some water which I can only imagine will kill the engine if I keep doing it.

 

[Big Kahuna]

try some stiffer springs in your carbs.

I would have to disagree here. You rotate nice and fast on most of them. My experience is that you need two things....good height (leaving water) and good rotation (combo of leaving water and in the air). Your rotating speed looks nice and quick.... try and pop the nose a little more so that it buries down into the trough of the wake you are trying to flip off. let the pump pull all the way up the wake before worrying about what you do in the air. I had issues when I was trying to pull it around too soon and not letting the pump get me up in the air high enough. As the pump leaves the water stay back in the saddle and start to pull the pole to your gut and move your legs (still bent) toward the hood. I try to touch my knees to the hood.....the closer i get them the faster I rotate. Standing up only slows down the rotation. You have plenty of motor to do it on your own wake in my opinion.

I think you are off to a really good start. Rotating speed is the hardest thing to find and you have it....now let that motor get you up in the air.

 

[Matt_E]

I should mention that I don't have trim.
So any rotating I do comes from the wake itself and my technique.

I've had an exhaust leak from day one. Not bad enough to affect my engine but bad enough to turn everything black. I finally discovered where it is. The Highroller waterbox is not watertight AT ALL. I filled it with water and held it up. It sweats water from everywhere at a pretty impressive rate. I need to get a video because it would be hilarious if it didn't suck so bad. The ONE thing I tried to use from Dan and it screws me like this. Proves to me he did NO R&D, just slapped it together and hoped for the best. I'm truly shocked that the stunt hulls are holding up as well as they are.

Looking for a waterbox. Thinking of getting one from Berky unless anyone has something they want to get rid of. I just don't want something too loud. This one sounded like the ski was straight piped. Way louder than x-metal if you can believe that.

 

[Waternut]

If you can't find another waterbox soon, I've got some really tight weave fiberglass that'll seal it up with two thin layers. I've also got some fuel tank sealant that should withstand the exhaust temperatures that the waterbox will see but the inside of the waterbox would have to be cleaned first so probably not worth the trouble.

 

[McDog]

I started to try to clean it today. I was going to cut it in half and put a baffle in it too when I covered it with fiberglass. It seems so completely filthy with burned oil that I said screw it. Every square inch is like the area around the exhaust outlet on the rear of a ski. I'm not sure I could get fiberglass to ever stick to it.

Time will only tell:haha:

hmmm. Id try and salvage it first before moving on if its even worth the weight savings (not sure how much it weighs) Thats a real bummer, nothing like just getting on the water and having to tear into a ski a few weeks later...

 

[Aircraftsalz]

A lake ride will be a lot of fun!!!

Lucas will help you with the flatwater BF's, hes got those down, no trim & big plate to plate backflips.

Going to be a fun weekend....
