New technology in outboards by a Florida start up. Seems like an uphill battle, but I guess if you have a dream.

Don't know about the rest of it, but the freevalve thing looks interesting. Could have a lot of potential. |

Certainly an interesting concept. I have to be lerry. The internal combustion engine has been around for over 130 years, and there have been some mighty intelligent people dealing with this problem of HP out of high speed inline four engine. (They seem to ignore the M139 Mercedes 416 HP @ I have 6,750 RPM inline four turbocharged 2 liter engine.) I agree that the pneumatic valve train is very interesting, with elimination of the cam shaft...but more reliance on computers in a marine engine??
I am puzzled by the goal of reaching a million dollars in a go fund me project. A million dollars is a drop in the bucket in development and production of a radical engine--even a single race car engine. There are many sources of funding for the many millions it will take to go to production.
They have a 30 HP 2 cylinder engine--as proof of concept...I was running 30 hp 2 strokes in 1956... Does this 2 cylinder engine run? If so , why no photos of it, especially on a boat...
The other issue is sustaining a marine engine, especially one of 654 hp with 7,5 Liters. The "Seven" line of engines went out of business in the last couple of years, as did Evinrude. ....
If this engine is so radical and successful, then why is it not in race cars? (Or manbe it is a copy of a race car engine). BMW made a 1280 HP 4 cylinder racing engine which could turn 9600 in the 1980's... _________________ Bob Austin

I just stumbled on a post from a year ago on The Hull Truth...they had claimed then that there was a "proof of concept running 30 h p 2 cal engine. No progress in a year? Albert Araujo posted several times on T H T forum....posted today and claims the project is "on track". It seems as if many in the T H T forum don't agree. The owner gifted. himself multiple shares. The $1 share would be hard put to make any profit.
I would not "invest". |

Bob, I saw the same HullTruth thread and those guvs dissected the subject pretty thoroughly.
Lets just say I wouldn't bet the farm on it. |

And it had the resources, money, production capacity, industry knowledge, sales & dealer network, etc. of Volvo behind it.
Now Mercury has brought their V12 to market at over $100,000.00 per.
Maybe a good concept but a very limited market. For my 2c - if somebody has the coin to repower their offshore battle wagon I suspect they will opt for the Merc as opposed to gambling with an upstart company.
