Worlds Fastest Cobalt?
 

Set of Saris Racing 900s being installed in a 343 tomorrow, should have results soon. One hell of a sleeper!

What drives?

Details!!! Please!!!

Very interested in knowing what comes of this. I recently sold my 343 and miss it!! Please keep us all posted on the results of this transformation.

XR Drives
Ran in the low 70s with 525s, then we whippled them, ran low 80s. Now we have closed cooled whippled 540s with good heads making 900 on pump gas. Should run well :)
Second motor is in. Results sooner than later

Sounds exciting!

Subscribed!!!! A new friend just picked one up. It was buy far my favorite sport cruiser at 03' Miami Boat Show.

First pull was 93, not dialed in yet. Expect very high 90s every day. Boat handled it great too, laid down perfectly!

Wow. That is some wicked speed. Congratulations.

Very impressive, sounds like a cool project but the worry over the drives would offset some of the thrill / excitement. Any discussions about upgrading the drive package??

There's a been a few of these 343's w/ upgraded power. Here's a whipple charged 525 Cobalt 343.

I plan to have me one, once the Skater 30 is gone.

like to think it will do 100 keep us posted trying to get 100 out of 34 sutphen tsunami race boat. we just installed 725 blower motors.. first run 28 props to small 70 at 4000 82 at 5000. never ran more than three quarter throttle. 32 s on the way.

Try putting Kiss Cote on the bottom and drive lowers, I picked up 2-3 mph on my 343 with this

That may very well be this boat in that picture

I don't believe so, the boat w/ the whipples is in Ohio, original owner, install performed by Sterling is what I've been told.

today with 32 s 96.8 one motor 6000 one motor 5500 bad fuel pump.. it was already replaced with one not exacty the same one as other. we were told it would work the same . it died at end of day . it needs 34 s . and proper pump 100 mph easy . can t wait. 34 sutphen tsunami. race boat. new 725 blower motors

That's very impressive, nice work. Are those Merc or Herings. 4 or 5 blades if you don't mind me asking?

tsunami triple digits
 

regular 4 blade mercs. no lab finish probably would be overkill. we do not want to get to crazy with that boat.its not that heavy and top speed in its history was 98 but most of the time it raced with 570 s top speed 86..we will go over 100 then probably stay in the low 90 s,even on a good blast..well at least thats the plan.the cornering on that boat at 70 to 80 is unbeleavable.its the real deal .so glad i got this thing.

The Cobalt is at 98 and runs out of prop, 32s on 1.3.6 gears. 34s are junk (bravo 1s) so to 5 blades we go!

You guys have done an amazing job with this project. It's kind of like the pontoon boat at LOTO, the ultimate sleeper!

Its beginning to look like I may have to talk to Jason about upgrades. I may get outrun by a Cobalt!

When can we see a few pics of the sleeper??

[ATTACH=CONFIG]504140[/ATTACH]Ill snap some of the hull today

That looks just like the one I mentioned a few posts back only yours appears to be a little cleaner & neater rigging.[ATTACH=CONFIG]504141[/ATTACH]. This particular boat is a blue hull w/ yellow stripe supposedly out of Ohio that belonged to a John R.

We tidied a lot of the rigging up for the customer. The only Merc parts left on these engines are the valve covers and the closed cooling.
This one is blue with a red stripe, and says Special K on it in small letters, owned by a John C. Small world!

You've done a nice job w/ it. Looking forward to seeing & hearing about the finished product.

If nothing else this boat can be crowned king of the sleepers on our lake :D
Its surprised a lot of people!

Are you all done w/ it & have returned it to the customer??
You need to post at least one GoPro Vid of it dusting off a Perf Boat just for chits & giggles.

This is all very intriguing but lets see a few picturres and if your feeling kind... a video!

Gotta see some pictures of the sleeper.

still no pictures or video??:(

He enjoys embarrassing Fountains especially!
EVen lined up with one of the 28 Skaters we built, didnt get him, but surprised the hell out of him when they were still side by side in the mid 90s. Its not the top speed that is so impressive with this boat (although at damn near 100 its pretty fast), its the pull from 70-90

No drive problems yet? Cool boat.

None so far! Although when we built the big motors we freshened the drives up too.

I know im slacking on pictures, let me know if this video works...and I know...the silent choice is on lol

Didn't work.... Sounds like a cool,boat

Ill figure out how to make the video public, I think thats why it wont work

you better beat 96 mph, put my 632 ci bbc out of my drag car in my 252 you boat is a lot bigger than mine but it is still a cobalt

Pretty sure it can... How much hp in your drag motor?

little over a thou, just did this the end of last summer, still need to find the sweet spot with the trim tabs (just put them on too) before the tabs that thing was like a squirle looking for a nut

Was just made aware of this, it isnt my job to string the customer's boat out...but I'm sure we can get a GPS reading out of him this spring. Very impressive numbers for a 25!

Didn't you mean 35'?

The 343 is MASSIVE it may even be longer than that. It certainly feels it.
I was commenting on Liquid Longer's boat though.
