Recently, while looking at options for repowering the Whaler 27, I ran across this new beast. If you are interested in the state of the art technology, and you have 70 grand laying around to apply to repowering, this is the cat's meow for sure! There is a video on a facebook page showing 3 of these monsters attached to an Invincible 42, a CC offshore fishing boat, doing 81.6 mph in flat sea conditions. They don't even start the engine efficiency comparisons below 40 mph! The triples on that Invincible 42 are drinking in excess of 160 gph fuel at the 81.6 mph :)

I went with the Yamaha 300's...saved about $20 grand, should get a bit better fuel economy, and I hope I am NEVER on a Whaler moving at 81.6 mph!

1100 lbs for 557 HP. About the same lbs/hp as the big outboards.

2lb per HP.

For 1,100HP dual vs. a triple, 2200 Lbs for Seven Marine.

For 900HP, 1800#'s for Mercury, 1500#'s for Yamaha....plus Merc and Yamaha offer lots of electronic controls etc.

Another drawback would be the concentration of weight, of the 1100 lbs vs. spreading it out with three 600 lb engines.

And then the warranty, service and parts unless a person was boating in range of the factory and the factory is in Wisconsin vs. FL, the capital of the go fast boats.

Wonder where they see the market for them?

Here are some boats built for FOUR 300HP Yamaha's.

There is a big market for these engines Eagles. In the Florida area, and in the Gulf Of Mexico here where I fish, there are a LOT of people with way too much money, and the need to be rid of it! The rule now for offshore tournament fishing here is you need big, and I mean BIG, center console boats, 35-45 feet with a minimum of triples. I call this the "offshore bassboat mentality", these guys fish in all the tourneys around here, and they don't care at all about your "efficiency", all they care about is getting 100-200 miles offshore before any other of their competition can get there. The idea is that the first boat on the bite will win the tourney. If they win, they will pay for the fuel, if not, they lose. High stakes gambling for a crowd you are probably not running with out there. I know I'm not running with them here :)

If you look at the site a little more carefully, you will clearly see that this company actually has located the majority of it's suppliers and service centers IN FL.

Also, you will note with a bit more in-depth reading, they will send you service if needed under warranty or not, no matter where you are located if you spend the bucks for these engines.

Chuckle...we call 45 ft center consoles "tenders". The real sport fish crowd go out on big boy boats. Last company boat I fished was 70' Viking with twin 1300 HP TI Detroits. As for gambling, that's toy money when the boat is a couple mil and yearly upkeep with crew runs in the half a mi range. The Calcutta pays for the party and tips for the crew.

i could see a company FL marketing the engines to a niche market, but a company in Michigan? These are going need a lot of TLC to keep them going plus controls are third party vs. Merc or Yamaha factory joysticks. The weight and torque concentration on the transoms is likely to create some issues. And the four outboard designs already on the water with Yamaha and Mercury over power them already.

You obviously live in a different world Eagles. Those 70' Viking crews are running WAY behind these boats and motors I am talking about, and they lose the race EVERY time. That was my point.

As to the price of these rigs, you better look again. The boat I saw running triples at 86.1 mph cost 750 grand. It burns fuel in excess of 160 gallons per hour. Those diesel powered boats are much slower than these fast CC's. They cruise between 35-45 mph and use less fuel doing it. I know, I kept a 53ft Hatteras over in South Carolina with twin 1200's for many years. Believe me, what I am telling you is what is going on right now, right here in the Gulf Of Mexico, things have changed. The old Vikings, Hatteras, Luhrs and Bertrams are still around, but they get used as charter boats or cruisers primarily. The tournament gamblers are all switching, but of course, some of them still also keep their big boats for living on and cruising. If you look at any coastal tournament on the Gulf Of Mexico, you will see the winners boats. You would, judging by these remarks, find this very interesting indeed.



You still don't seem to get it, The company IS marketing these engines in FL.

The only people buying these motors are the ones buying brand new boats designed for these motors.

Yamaha and Mercury are not even presently IN THE MARKET that these engines are in. The biggest either of these manufacturers have available are 350 HP. I cannot understand your math at all, as 3 of the highest horsepower engines Yamaha or Mercury make cannot EVER equal the same HP as 3 of these monsters. How on earth can you insist that " And the four outboard designs already on the water with Yamaha and Mercury over power them already."

Well 50+ mph on the big boy boats like the 70 Viking is standard option stuff, the big boys can and do go faster with Arneson Drives etc. The big center consoles were a way for the little boys to play the game. And the luxury living on the big boats is the sweet life.

"Difference between men and boys is the size of their toys".



The 70 Viking runs about $5M. And it's middle of the road. As for fuel, you don't think about it if can afford one.

i could see a company in FL marketing the engines to a niche market, but a company in Michigan? These are going need a lot of TLC to keep them going plus controls are third party vs. Merc or Yamaha factory joysticks. The weight and torque concentration on the transoms is likely to create some issues. And the four outboard designs already on the water with Yamaha and Mercury over power them already.



Exactly the point, the company is in Michigan, not located in its target market area to provide service and install etc, issue with controls etc. This is exotic stuff, lots of third party controller interfaces, structural issues with boats etc. in addition to day to day care keeping them going.

Designs like the one shown above from Morelli and Melvin using FOUR x 300's over power it and use the Mercs and Yamaha's with integrated controllers and lots of service available.

Inboard Arneson drives will beat them anyway. The multi-outboards are a way to save money and they get somewhat impractical as you can pack 4000 HP into a go fast Arneson drive vs. trying to hang eight 500HP outboards and props off the back.

The specialty outboards are a niche in a niche market, too expensive for mass market and there are better solutions if you have the money in high end market.
