so i take it the pods are still on . . . . :D

So far but like I said, the rev limiters are still on:D

well keep up the breaking in :angry-smiley-044: can't wait to hear and see some video of it after that's done!! :coolcowboy:

Artie, thanks for sharing, we hope to see you out there sometime soon

My daughters and I took the skater out last sunday to try and get some "under load time" on the new powerheads.
Really loving the way this thing handles

Dave any update?? :boat:

Made it to lake yesterday, finally got the rev limiters to release!
here's a video

Great video! How fast we're you going?

Sounds really SWEET - ya' just have to love 2.5's running in harmony!

thanks guys, Going by in the video probably close to 95, and I didn't know that the rev limiter was released yet. We kept going and it was an awesome sight to look down and see the needles on all four tachs leaning way over towards 8000 range. we ended up with what you see on the speedo recall.
I'm ready to start dialing in now, the props I have on now are a just what I threw on to get her on the water. The 2 center ones are thick bladed15X34 stock merc cleavers off the shelf and need blueprinted
The outside motors are spinning 15X32 stock cleavers. Your help would be appreciated

"Congratulations"

Congrats!!!! :ernaehrung004:

That is AWESOME David!

Sweet :):):)

That's great news, if you want to bring it to Indian lake where it may have a little more room to stretch its legs let me know.

Thanks guys, at least I'm on my way to get to my goal. I'll start experimenting with different propellers and engine height. The fun begins!

Hello David: My name is Jorge Cintron, we have a Mercury shop in Puerto Rico.Our boat is a Motion 35 with 3 280s.If you sent us your email adress
we can sent you photos of our boat and rigging.You have done a beautiful job with your Skater.Sincerely yours; Jorge Cintron.

Jorge I just sent you a PM :boat:

Thanks Jorge, your Motion sounds like a cool set up. I'd like to see photos

I'm glad I've got help

we were out on Buckeye Lake yesterday getting some tach readings at WOT, all 4 engines at 8000 + with 15X32 outsides and 15X34 centers

Dave excuse my ignorant question , but why different size props? :confused:

Hey David,
You didnt notice the paparazzi behind you while getting on the freeway at the end of the day? My sister who lives in Pickerington had a sighting. She called and was all excited she was following a skater while getting on the freeway. She was taking some pics with her digital camera. When she said skater, I knew exactly it had to been yours. She was surprised I was able to describe it and new which boat it was.. She said it looked good under tow!
Jr.

I've been under a rock lately and just found your video. It just made my day. I love that sound!

Looks great

The center 2 engines are mounted 3 inches higher than the outside ones and as a result turn higher rpms, Sometimes the use of higher pitch props can take advantage of this and add to top end speed.

I'm glad for that Skate, you and your family have been through a lot and it makes me feel good to help anyway I can :)

that's cool J-B, with OSO its a small world, tellem thanks for the compliment!

Gotcha, thanks bud! :ernaehrung004:

Props being sent to Dewald

Wife got behind the wheel for awhile last weekend, and did quite well, I think she's hooked:D

Nice job looks great

"Makin Memories" It's what we do. Looking Good David.

From Saturday. Working on the video

good to see you out there Artie. I didn't know for sure if that was you at the time. Your Formula looks great! Thanks for posting the pictures, and looking forward to video when you can.

It looks like you have the rotations arranged with each pair rotating out, have you tried it with each pair rotating in? Are you running all 1.87 ratio cases? I found that taller 1.62 gears not extreme prop pitches was the answer for both acceleration and top speed. I could never get any of the 32" plus pitch cleavers based on the low rake Mercury castings to run like the calculations indicated they should have. I do have some Mazco mid rake 33" cleavers that run great especially with 1.75 ratio. I know of a triple engine Spectre that runs best with 1.75 ratio cases on the outer motors and 1.62 on the center. There was a guy on one of these sites that had a couple of almost new sportmaster housings that ended up with cracked skegs from being thinned too aggressively. Those cases with the skegs ground off completely could be just the ticket to reduce drag and prop slip on your center motors. I also doubt you need full 15" diameter wheels with four of them in the water. Lots of permutations to consider to maximize the matrix with as many variables as your quad represents.

i had a 30 chris cat w /4 2.5s efis iran mine left right left right out boarding w/15x32 3blades on outside moters and15x34 4 blades on inside motersran abest of 118 @7600ish rpms you might want to try some different combos to see what happens

You make some interesting points. Right now I am running the inside motors in, and the outside motors out. I have the 1:87 gears. Correct me if I'm wrong but I believe that with the 2.5 sportmasters, I'm limited to 1:87 or 2:1 gear ratio.
With the current setup I'm experiencing over 15% slip which I'm hopeful that with the right props I can get that down and top end mph up.
I'm having to face the fact that the merc cleavers with the 18 degree rake might not be the best for this application. I've got Dewald working on a set of 4 blades to try on the center motors first.
That might not be a bad idea with the skegless center motors. A little nervous though about lack of extra insurance in case I would for some reason break one of the outside skegs.and lose steering control.
The beauty of all of this is, there is so much that I can do with experimentation on props, prop rotation, engine height and weight distribution. It's just going to take some time. I appreciate any tips or advice you guys want to send my way

Runninragged would you mind posting some pictures of that Cris cat quad set up. They're so rare, it be great to see how yours was set up. It sounds like my setup with the prop rotation is the same as what you had run. Is it still out there runnin?
