As an outboard Enthusiast and a bit of a engineer here at home I've always been intrigued by the seven marine outboard after seeing this video I have to say wow an American company with the Ingenuity to take GM's very reliable V8 put a marine cooling system drive system and a supercharger in a compact easy to service outboard configuration with a custom looking and sounding exhaust system Cal and LED lighting I think we're going to see this motor dominate The large boat Marketplace, starting to see some of the big-name large boat / yacht manufacturers embracing outboard power as well and it only makes sense they're easy to maintain in a large boat configuration and you don't have the toxic environment inside your boat from an inboard engine and drive. Maybe 10 years from now I can afford to buy a used one.

You didn’t mention anything about the outboard’s environmental impact compared to other outboards. And what about an outboard jet type propulsion to cut down on marine life damage? Another thing about outboards is the convenience for repair. How easy is it to service? How do you get it on and off, with a crane? Is it OK for it to be on a boat that is docked and therefore with the propeller submersed for long periods? What is the life expectancy of this outboard? Is it equally at home in ice cold waters as it is in warm tropical waters?
@DeadeyeLefty6 жыл бұрын
If you knew a little more about outboards, you wouldn't ask those questions. There's an emissions decal shown on the engine that every certified tech will recognize, regardless of make. Every. Single. One. Every owner of a new boat engine has seen at least one. Even people shopping for one online have seen it. It very clearly answers your question, yet you still asked the question. Think about that for a minute.
@松田もしくろす6 жыл бұрын
DL- Seems as a consumer, I need to do my own homework. Emission standards are vastly improved for outboards from what they once were. I apologize if I sounded alarmist in any way.

Fascinating engine. If it turns out there is a large market for these huge power outboards, I suspect additional vendors will join the party. I wonder if some one is seeing what changes have to be made to these LS motors to run in a vertical orientation. If they can be adapted without to much trouble, then you would sea a significant efficiency gain, simplification, space savings, power gain, weight loss, and cost savings. 7 marine will need to do that to remain competitive in the future. And Volvo Penta is still Swedish. Chinese Geely owns only the Volvo car line, which they purchased from Ford which owned it for a while. Volvo AB is still 100% Swedish and makes buses, heavy trucks, marine and industrial engines and more. And I will still call gasoline gas here in North America. I will call it fuel or petrol or whatever term they use when I am visiting those areas which do not use the term gas or gasoline.

They have a revolutionary invention called an inboard/outboard, uses an iron block v8 truck engine and does not need all this complex gearing/custom parts.. Every gear wastes energy and efficiency, that's why outboards have not used a setup like this before. Also supercharging and turbocharging is great for cars that need the power for a few seconds to accelerate but with a boat you need constant power, I would be real skeptical about the longevity of these car engines being used for boating..

The 627 is not a boat anchor unlike over marketed mercury, they put a corvette with a zf transmission, and like dunderogbrak the gearcase isn't Seven Marine's either. Either way this is an awesome innovation and they can own that. Infact, they only should advertise it as an innovation on the water, after all they have achieved incredible hp to weight ratio. That was what the spokesman should have said. Look at the car companies calling fuel injection new. how about direct injection? its all old technology. The diesel engine was the first fuel injected engine ever. In somewhere around 1806. It was around 1890s rudolph diesel made the first direct injection. The whole world is educated. So why do these manufacturer's still think they are fooling people like the car companies flat out lying calling it "new technology" ?

All this speculation and guessing about drivetrain efficiency. Just do the math. At BEST each gear change is 95% efficient (depending on the type of gear, and assuming very little speed reduction). From the output shaft of the motor, I counted three straight cut gears, the ZF transmission, one straight cut torque splitter, and two bevel gears on the lower unit. Assuming the transmission is 95% efficient (big assumption), that gives 0.95x0.95x0.95x0.95x0.95x0.95x0.95 or approximately 70% efficient best case and 428hp at the prop. I'm not making any judgement on the design merits, only putting some numbers behind the speculation. I'm guessing a vertical shaft outboard gearing is 85-90% efficient for reference. Also for reference, in an automotive application a transmission and differential are 80-85% efficient at best.
