Seven Marine no more :(

Cant say this was a surprise....i figured Volvo bought them thinking they just sit back and the engine would sell themselves.....i dont think they put any effort into it...now its all about going green. :rolleyes:

Shocker! I know I don't get out much, but I don't think I ever actually seen one of those mythical beasts in the wild.

Wonder why they bought them, it was only a little over a year ago?

It was a little longer than a years ago:

Regardless, with the likes of Mercury Marine closing in on the Seven's then exclusive horsepower levels; it was only a matter of time. Seven Marine went the way of Ilmor: exotic, "romantic" in it's exclusivity; but just not an enterprise player. The Sevens did have their issues. The high output numbers are exciting for folks like us; but they could not handle being on lighter/smaller boats, as they can't handle the leaving the water and re-entry like the lower HP outboards. That's why you never saw them on performance catamarans. Combine that with the transformations of the LS platform over the years; and re-engineering the Seven platform to follow, likely didn't make good business sense based on demand and sales.

The other "bonus" of a boat with Seven Marine outboards was the ability to use less units. Take a boat that would have required 2 - 627s to be on par performance, compared to a boat with 3 Mercury 400s...
...if you lose one of those 627s while out a sea, you are in for a long ride home. More than likely, if you lose one of those Mercury 400s, you can still make it home on plane with two of the 400s.

With increasing outboard sales lately it's surprising to see these guys AND Envinrude now being sent to pasture. But, I've never seen a Seven on a transom anywhere and newer Evinrudes are few and far between. Mostly Merc, Yami, and Honda.

They are definitely down here in the high end Florida market. I’m sure there are some LOTO but I don’t specifically recall seeing them.

saaaad!


I especially liked the LSx motor platform --> go to junkyard and replace bad motor






.

Didn't know it had been 3 years.

Personally i never really got it, people like OB because of reliability, true marine design etc.

A 7 was just a I/O motor strapped on the transom. I do like the LS platform and need to spend some time learning about them for a repower.

Agreed there is a lot around here but also not shocked they are done.

It cost too much, weighed too much, and wasn’t faster than a verado boat with more engines.

I liked the engines and the concept overall though.

with the election result looming, they're planning on "transitioning" from fossil fuels:rolleyes:

New for 2021 !

They were like 80-90K each......Pricey when you need 4-5 of them!

HCB used them frequently, Nortech did a few boats with them. I'm shocked Volvo didn't try to sell the brand to someone else rather than just closing up shop.

I loved the flag blue with red boot stripe 47 intrepid that had 4. They fit the boat perfect.

Stefan Edberg was a great tennis player, ABBA was a huge phenomenon, IKEA is still booming and Volvo pioneered the duo prop but how did the Swedes ever think they could compete with the American muscle of Mercury?

Must have been dreaming. 😊

RR

If you'd have told me I'd ever hear the name Stefan Edberg again I'd have told you I really don't think so. But, NEVER would I have thought it would have been on OSO!!!!

"To do its part, Volvo Penta says it is significantly accelerating its own sustainability projects to reach zero emissions via fossil-free, renewable fuels, electric and hybrid technology."

What Kool Aid are they drinking over there?

You can substitute with Bjorn Borg if that sits better.....🙂
(I’m running out of memorable things from Sweden)

I’m not surprised...seven was an expensive garbage product with tons of issues.

About a year ago I went to the Mercruiser parts desk to pick up some lube and such at Palm Beach Yacht Center. There was a Midnight Express with 3 hanging off the back and all the lower units were off. This was a boat that looked new, I mean the trim tabs and paint were pristine. I walked up to the mechanic and was like wow, did the guy hit something? He said no, maintenance, we need to put on 3 new lowers. I was like? Really? The mechanic went on to say yeah, we repair these all the time.

I threw up in my mouth and walked away...

AOC and Kamala must have made it for them:violent-smiley-021:

My business has me dealing with folk in the U.K. and the Netherlands frequently. Make no mistake, these guys are DAMNED intent on the whole 'going green' thing, with various pledges of being "zero emissions" or "carbon free" by XXXX date, usually promoted to be within the next 15 years or less.
Seriously?
For one thing, there simply isn't the infrastructure in place to even begin to accomplish this. The list of why it can't happen within the time frame desired (if ever) goes on and on but it's not popular to denounce the effort. As others have noted, we have similar freaks over here thumping the same drum...Bedpan and Kameltoe, along with AOC, just DREAM of this.
Crazy.

Good luck selling a boat with these now

You know I see nothing wrong with pushing forward on new technologies. If all engineers said no way can’t be done, Elon wouldn’t be where he is at.

I mean who would have thought that you could “fly” a first stage rocket back down and reuse it?

The time table of 15 years sounds a bit aggressive but on the fuel cell side, in the mid 2000’s the car companies were testing them. That may not be as far fetched as we think.

never say never.

I completely agree with your statement. Horsepower from electric motors is not the problem currently, it is only the energy density of the batteries - which is currently only about 1/10th that of gasoline. Once the battery technology advances and the energy density approaches that of gasoline, we will see electric everything - cars, boats and even airplanes. I do hope that everybody goes online and educates themselves to the fact that our ships and trains have been powered by electric motors for decades now, with either diesel motors (trains, commercial ships) or nuclear reactors (military ships, submarines) providing the source of energy to create the electricity to power the electric motors. The first flight of a commercial aircraft has already occurred last year when a converted De Havilland Beaver seaplane with a 750hp electric motor/battery system developed by MagniX flew a short route up in Vancouver, Canada. All electric is coming guys, it's just a matter of time.

Well said and explained. Check this out (I'm sure you already have), https://nautique.com/models/super-ai...gs22e/overview.

I think they were a hard sell before....... Intrepids/HCB might have to rethink their designs with the lesser HP offerings from Yamaha/Mercury. A quad 627 boat (2508 HP) can't be replicated with 6 Yami/Mercs hanging off the transom of a 11-12 ft beam boat.

Thanks Matt, I actually had not seen that yet. A friend of mine told me about it recently, and I just never took the time to research it afterwards. Pretty amazing that they can get 2-3 hours run time out of such an inefficient hull design. I also heard that a guy mounted a Tesla car motor (400hp) on an outboard midsection, with the batteries in the boat. There's also currently a boat in your neighborhood Matt that will make waves in the industry when it is completed, but I'm sworn to secrecy on that one..........

I remember when growing up and going to the boat ramp and
most of the time, seeing a random boat equipped with a tower of power tied to the
dock with the cowlings opened up and the owner cranking on it
endlessly trying to get it running ( and usually swearing )

I can’t image trying to keep 6 of those running all at once;)

What are they going to do in California, they have rolling black outs now, they can't provide enough electricity to power homes. How are you going to have enough electricity to charge your car, boat and keep the lights on in your house or business?

Electric motors powered by generators run by giant diesel engines!;)

^ Exactly! A bit off topic here but behind those electric motors is a big fuel chugging generator. And that spent fuel from those nuclear reactors is easy to dispose of...

aoc is building a solar powered 747 in the vacant lot next to her house. She used all China parts. What’s the worst that could happen

Not to split hairs but...no, nuclear powered ships don't use electric motors to drive the ship...they use the reactor to generate steam to power steam turbines...that drive the ship through a gearbox, not via electric motors.

I think we'll see more vehicles powered by electricity in the future, but NEVER to boats like ours...ain't happening, at least in our lifetimes, not without some unforeseen technology 'breakthrough', anyways...and still, at least 25+ years off. For the foreseeable future, nothing beats fossil fuels.

I predict a lot of boats hitting the market soon as between the tax hikes and war on fossil fuels. A lot of people won’t be able to afford recreational performance boating, let alone refitting their rig with electric motors.

Eventually diesel may be the remaining fuel source for internal combustion engines as land based transportation migrates to electric. Diesel would still be in use for some big stationary applications.

You may want to do some research before posting..........

Yeah, you are right. Its coming but in heavy torque applications, the tesla tractor-trailer had 25,000 pounds of batteries. So yeah, its coming for cruisers but for performance boats we are still many years off. FWIW, a good friend of mine went to Georgia Tech and his degree is in advanced power systems. All of this can be done, but its not a question of if, its a question of cost. For comparison, over the last 3 years there have been a lot of speculation of people cheating in high level cycling, both Tour de France and Olympic Mountain bike style stuff. I was laughing and talking to him about this with an attitude of like yeah right - the battery would be huge. He laughed at me and said dude I have motors with enough torque that you could put in the hub and batties that are the size of a few C batties and could give him enough of an advantage that would last for 6 hours and enough power to win the race. So, the technology is there, its the production costs.... which will eventually come down.

....another thought.

Its been hard enough for me to mentally adjust to the sound from a 100mph boat that had 1075's to a 100+ mph cat that has much quieter outboards. Now ya'll want to make them totally silent. SMH
