They have not been officially released to the public for sale yet. That is why nobody has seen one on a boat in use.

I was just reading in "Prop Talk" a local boating puiblication, they are expecting to be released for sale this summer.

Although they have been advertising 7 marine was still testing this motor.

This is the 40 Freeman. This was their first boat and I believe only 40 made. She is cold molded, heavy, and a wave crushing tank... she runs with said power 60+ mph. Billy is not using this cold molded method anymore.

We are working on a 34-37 x 11' CC cat, stepped, resin infused, vac bagged, CF and Kevlar auto claved cat with the twin 557's. or quad 350's.. These 557's from what I have been told are being refined over and over so as when they hit the market the majority of the R&D has been done vs making the consumer the guinee pig....I can apprieciate that..hopefully a few will have been sold so we all can get some feedback.. It's great to have options. Jeff

BELT DRIVE......



And we have a winner! We posted here not to spam, but to let you guys, who we do recognize as a significant piece of the marketplace and value accordingly, know that we will be at Miami this year (booth U90, slip 410) and we WILL be releasing performance and fuel burn numbers when the show opens. And if you won't be at the show, we'll be posting all the info and fuel charts on our website, our Facebook page, and here.

Please know that we would love to be able to disclose everything right now, as the anticipation is eating at us as well, but cannot and will not do so prior to Miami. Liken this to a movie release; if a new film releases on a Friday, the studio does not leak it to the internet the week before...

That said, thank you again for all of your enthusiasm; we look forward to meeting as many of you as possible in Miami, and are excited that a handful of THT members have agreed to join us for sea trials.

Jeff thanks for the info, Interesting.

"...We see quad four strokes every time we're in the Keys. That's 3200+ lbs!..." 0/B Sonic


IIRC a 2 stroke 300 weighs 505lbs. A 4 stroke 300 weighs 630lbs. So four 4 strokes weigh 2520lbs. Unless my figures are not correct...

Will the sponsons on your boat look like Skater MTI Nortech etc or will they have the sharp forward entry of the Freeman?

Twin O/B Sonic

the 350 Yammi V-8 which is advertised @ 804 so add 20lbs for fluids and you're @ 824 X 4 = 3292!

On the D.I. 2 strokes a 300 E-Tec is 528lbs X 4 = 2112

Most of the mfgs weight claims aren't even close either. Seen them weighed independently in boat mags and most recently on Ship Shape TV. I think a 200 Verado was 680lbs! add 20 for fluids and we're @ 700 lb's X 4 = 2800!

I've been around several large dealers and fichse bote builders to hear their concerns of transom loading. Most are probably fine at this point but when the 4 strokes hit the market most were not.
Worked at one dealer that sold a new, very popular brand 33' fische bote w/triple 350 Yammi's on it and it was breaking trim tab rams trying to keep the thing on plane at low speeds. Owner and Captain got stuck coming through the Gulf Stream off plane due to this. Too rough to plane and wouldn't stay up at low speed due to tab issues.

Also kinda curious how Yammi can claim their new 250 HO is lighter than the 2 strokes when they don't have 4 cam shafts, 24 valves, timing belts and pulleys etc, etc. Waiting to see that one on a fish scale too

CAT..The ride is all in the entry. If the deadrise is constant to the bow it will be harder riding than a variable deadrise.

It's all about the ride on these types of cats...and with said power get the best fuel economy. They are made to troll at low speeds, get up on plane quickly, and there is no hop. My goal is to make a 34-37'x 11' stepped version that will be in the 80+mph range. Thanks Jeff

Guess I should of looked at the weights first...
My other question is whether they have marinezed the upper end. Running at a constant load at 4000 rpm I am not sure the valve clearances have been adjusted.

GM used to have a marine version of the LSA on their website listed. That was before the bailout, who knows what happened to it from there. If Seven was smart, they let GM do the R&D.
Hey, what do you know, they still have it listed for 2012.
