- SUBSCRIBE OUR CHANNEL ua-cam.com/users/theboatshow... The Boat Show will show you the sensational factory of Seven Marine, where the most powerful outboards on the planet are built. We will see every single component of the engine and how Seven Marine was able to bring all this power in an outboard.
The 627. New cylinder heads and camshaft, an uprated fuel-injection system, and revised ECU calibration combine to make the most powerful outboard on the planet even more powerful. The increased power translates to an engine that pushes the ever-bigger Super Consoles with ease, simultaneously delivering class-redefining performance and improved fuel economy. Multiple gearcase options and a selection of gear ratios in the ZF electronically-controlled wet clutch transmissions allow Sevens to be tailored to any application, from utility to pure speed, and anywhere in between

I can remember as a kid in the early 1960's that the most powerful outboards were 60 bhp. How far we've come.
Saw an Estrella with 5 of the 627sv motors on it. Magnificent.
Excellent design and build of a great outboard engine. 627 horsepower in an outboard !!!
WOOOOWWWWWWW !!!!!
Strange that a small family run business found a gap in a huge well established market dominated by big players. Well done.
Amazing! Those seem like a one of a kind experience
I'll be 100% honest: this video has changed my mind about what an outboard is, and can be. Wow.
Where is the engine cooling circuit? Now im intrigued.
holy crap..Seven has just revolutionized out board marine in a very big way...now the sky is the limit...unbelievable ...love it...need to own a fuel station to own the damn thing..but wow...BB
These are truly remarkable out board motors
I wonder if you can get a 3 to 1 ratio gearing so you can have surface drive performance for skater catamarans using outboards.
A beautiful design ❤
come along why since 1981 with a 75hp Johnson on a flat bottom 17-foot pile
Very good video, and clearly a fantastic product, for the high end market. Do you need a uk agent?
How do these compare in weight to other manufacturers? I like the idea, and the chevy engine. Just can't imagine the cost and know I could never afford any of the new stuff but enjoy learning about it all!
Is there a market for a V4 in the future? Is that going to covered? It sounds. Like a good power system.
wait what each of those is near 500kg? or all 4 is 500kg?if they are 500kg alone so it would be 2tons 4 of them at the rear?
I love the reasoning behing the 7 in 7 marine. I want to see that 135cc kart footage. Did you race with senna?
They should make a 7.77 liter displacement outboard with 777 hp, 777 pound feet of torque, a weight of 777 kg, with a price of $77,700 😜
Was it tested in sea water or just fresh water from lake mich..
Is it still just a one speed transmission?
Ah yes, the ubiquitous LS motor. Gotta love it!
With this 90° layout and gears you can make a commercial diesel model that a lot of boat enthusiasts would buy and it would also bring you a beter fuel economy and efficiency:Jaco Nice from SA
7 marine totally insane the best of the best.
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 will not see these on working boat Pleasure boats yes but not working boats
@@dexter2433 - Many "working" boats in Oil, Seismic, Salvage and diving use outboard motors .
you meant to say a Swedish company, which it is by now.
That is about a 1,100 pound motor..The power is amazing..
Yay Cadillac! 6.2l engine sure is big for an outboard! Glad my Caddy only has the 3.6l with 310hp! Gotta tiny gas tank! Lol
How about that vette engine as an inboard?
So I wonder what is the best fishing lure to use?
I grew up on boats on Lake Michigan, miss them but I will always remember my Dad saying........the definition of a boat is a hole in the water in which one pours money into!!! LOL, that’s why I’ll never own a boat unless I win the lottery.
Damm Fine power plant!
I’d like to see those spider gears in the lower unit after about a season of use. Like doing a one legged burn out. The shit don’t last at high RPM.
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.
Gotta love 600LPh @ WOT Jeezless! Cool Motors though
dammnit they went out of business i was looking to see if it was cheaper to get a corvette engine through these guys for a custom offroad vehicle
Can you guys make a 4 an 6 cylinder version for those who can't put that weight and power on there transoms
Muito bom q maquina
A Duramax version of that would be cool...
I was on a Salmon Boat in AK 46 feet would do 50 knots 2 502 mer cruiser motors was the fastest salmon boat of that size in AK at that time
So, where is the heat exchanger for the glycol [ie. fresh-water cooled] powerhead? On board the boat with a keel cooler? I don't get it, but no matter, I'll never own or service one of these Frankenmotors anyway.
They “LS”ed it!!!
Gee I would love to work in this factory . Nice to see Volvo join as Well.
GM block based engines..... Does 7 Marine give you a OnStar button to call for a towboat when the engines break down or get recalled???
Means that monster at 1:40 is an outboard engine?
I’d love to know how much of that 627 horse power makes it to the water and how many hours they last? Marine engines are always working hard. Like a loaded truck in passing gear up a hill. Well maintained gasoline EFI marine engines that are mostly kept under 75% of rated rpm will last about 5000 hours. Add boost and you cut the life to less than half.
On a long enough timeline, everything gets an LS
They don’t need sea water intercooler , Just closed air water intercooler much better the motor is not that extreme for sure
That thing is really complicated. That makes me wonder how it holds up long term, and how much repairs will be.
They don't hold up. We have one in our marina and the zf gearcase don't hold up
Bass Florida Sure, have Toyota engineer the motors... if you want decreased performance and efficiency. Their V8 motors are the second worst in the market, right behind Nissan’s 5.6l.
I'd love to see Toyota build an outboard motor. They should send one to the trade school I'm attending.
@@removefromme Actually Yamaha own Toyota Shares... They are basicly the same company... Even Yamaha has build some engine for Toyota Cars.
@@REVIEW_JUJUR That's awesome. I wonder if Yamaha had anything to do with my Scion tC
They call it Seven marine because you have to work seven days a week to be able to afford the gas
HCAC BUILD: Its called fuel (petrol, Diesel, Paraffin, Gasoline, Kerosene etc.) not "gas" . . .
no it runs on gas
Nope means you work on them 7days a week
DeltaLou: Wow an intellectually challenged internet dimwit gives its contribution. Thanks you and good bye . . .
DeltaLou: Did you think up that retort all on your own? Did your "husband" help you write it down?
Personally when I look at these engines it looks like the creature from the movie Alien
Well OXE diesel also use several features seven marine say are unique for their motor.
I hope some day there will be an invention of super electric motor with same strenght with this machines which run by high octain gas...
gm + zf .... I know why they fit 4 on that boat...
I’ll bet the horizontal engine layout hogs a bunch of hp.
I’ve been in the marine repair for over 20 years. I can’t wait until I get the chance to get a good look at the outboard. 1 ? How much $$$
Patrick Rolf
Someone mentioned $90k
I suppose if you can afford 4 of them, not to mention the boat, ya ain’t gonna fix it. You’re gonna trade em in on new ones before the hours get too high. 🥴 shit, I just realized that is $360,000 in 4 motors.
I took a ride a few years ago in a 17’ feather weight pickle fork tunnel hull being butt bullied by a 2.5 Merc radical race outboard. After the ride he told me he had been radar gunned at 122 mph.
Yeah, tell me that AFTER my shorts are loaded. I’ve always loved the sound of a serious two-stroke, but this one had an ugly evil scream. ☠️ oh hell, you’re in the industry, that’s child’s play to you I’m sure.
I can’t imagine 2500 HP from four outboards that sound like just blowers and gears. No audio hint of v8.
idk, 270,000$ seems like alot for just 2400 horsepower of inefficient over stressed outboard motors
at what point do you just give up on this and go with a real inboard single motor with better efficiency 5/6/7 motors?
I want one of those 7 marine shirts (to wear to work)
Do they have a 7 year 100% warranty?
turn up the boost on those lsa’s make 800 each
Have to be mindful of not over-powering the drive train...especially when you could have those "Out of water Experiences" when the prop(s) lose resistance then suddenly get it back... That makes a LOT of Shock to the drive train...
I am sure they engineered a "margin of safety"...but as you increase the HP and Torque you 'use up' that safety margin... Not to mention the higher stress on the engine internals from the increased boost... All combining for less 'dependability' and more maintenance...and no one wants to get stranded with a dead motor miles from shore...especially not "Rich Guys" in their Very Expensive boats! (smile)
Also, they're 627 prop hp so count in drivetrain losses and it probably is 800.
so this means a person can get parts for this orphan now. I really like whats in it but no service was a no starter
Do they do a handtiller 15 hp.
funny
Thats massive outboard engine. But i think its too heavy for outboard.
use chain drivin instead of belts that can wear out and snap ...way better
with 4 changes of direction within the driveline, there must be a significant loss of power to the prop
do they asperations for a smaller motor? 300?
What would be the point? The markets already oversaturated in the 200-400 class
...and I bought a used Mariner 4 for $150... I was looking for 40lbs trolling motors and now here watching $100k motors while dreaming. if i were get one of these for free, my boat could not carry and sink :)))
I got zf5 in my f350, is this the same company?
Absolutely yes.
Soooo many gears and parts to the transmission path.
At least they didn't use a CHAIN!!!!!
Andrew Fletcher yea I wonder how the gear train feels when you shove 650 horsepower through it.
gotta be some efficiency loss there. not ideal.
Massive torque, massive gearing.
Welcome to 50 hour gearcase oil changes
Brilliant! I wonder if the transom on my bass boat could handle the weight. Methinks the C/G may also be a little high. These days, horsepower is pretty much determined by how much boost the lower end can stand. I'm sure the ECU is custom for this thing, and therefore you can dial HP up and down depending how large your attachments are.
i want to see a Dino run on output shaft compared to a Verado 350hp 2.6l then compare hp per pound at the output shaft any thing less i see nothing but a motor built just for show and a sticker with the #627 on the side
That's exactly what this is. It's a fashion statement, basically.
Columbia, Central America and Mexico? Remember the Don Aronow story lol
That's why people give up on boats...the fuel cost is excessive...$ 3.70/ gal.for ethanol free 91 octane. Twin engine installations never get over 1.4 mpg.
Definitely an outboard motor tailored for the rich, that or some governments. Don't think there gonna get many customers in the sport fishing market, maybe some in the commercial fishing segment. I know some commercial salmon fishermen in Alaska do like outboards, because they can remove and take the engines home for the season, while the boat is in dry dock.
Only 1100 LBS! So that center council 4400 lbs hanging off the transom. Or Basically a hellcat.
They are very heavy though...Seven Marine 627... 1094 lbs each...vs...Yamaha 350 or Mercury 400r...668 lbs each.
On a 4 engine set up with Mercury 400r's...thats a difference of 1704 lbs...if you don't need all that power the weight gain
may be unnecessary!
dont forget the diffrence in fuel consumption
8:13 they look like scared/shocked fish!!!
Should have used Dodge Hellcat motors instead and used seawater cooling. As long as you do a salt neutralizer after running, nothing beats cold salt water for hp.
7:58 600 LPH LOOOL xD
This engines should last long, longer than the V6, V8 counterparts...
nah I keep my twin 250 hp saltwater series mercury. my 31 ft contender get 60 mph and that's very but very fast for me.
Yep, I've been running Merc's since 1980, they are the best!
Still excited about that merge with Volvo?
any explain that takes that long. kinda scary.....
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?
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.
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. I have two outboards and they do have decals on them- I looked. But one outboard is never enough so we are all looking for another one to add to our collection.
very cool but you forgot to add these way well over 1k each closer to 1200lbs each wet weight. screw that get a Verado racing 400 and your set
1100 pound outboard whew
NOw give me a Torpedo Gear for my Mercury and I would like that!
Ridiculousy complcated . Four 600hp V8's to power that little boat is mad. How much to fuel them all, the range must be really small..
Draxindustries1 nah. Just radio in 1 of those refueling planes bro
It was sold to Volvo penta and they have discontinued production
Danm I wish I could be a part of this and being educated in ingeneering
Try learning how to spell first, that will help in the long run.
sailor Mac hahaha sorry excuse moi je caused ferais plus attention
My danm phone excuse moi he ferais plus attention a se que j ecris is that better
sailor Mac I think I made my point I really don't pay attention to the spelling really
Volvo penta own by chinese ?
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..
Well you obviously don't know a thing about Mercury outboards and their history.
Looks to be a great deal of parasitic loss of power with all the gears.
Built for the 1 percent
Just amazing! I am in awe!. What you have done is amazing. Just don't sell out for Billions! maybe you should. I'll come skipper your fishing boat on the island you need to buy.
I've never seen one on the water and i live on the lakes as much as i can. they cant be very popular...
They’re very popular in Florida, Bahamas and France 💦
Il video in italiano?
Yes, look up GTFOH
i want one on my johnboat
i want on my mariner 4
i think i can mount it on my 2,50m rubberboat :P
KoeleCat yeah totally. It will also act as an anchor for ur boat lol
But they did not reveal how heavy in the pocket when gas is concern...hahaha... You need to have your own oil refinery... Hahahaha...
So much has change since this video was posted. Volvo-Penta bought it, then after a couple of years completely shut it down. This engine could not compete in any way, with what Merc developed. Not in horse power and especially in price. The 7 was $23,000 more. Volvo-Penta should have known that before they bought 7. They need to up their corporate espionage efforts!
