Mercury to offer a V12 600hp. Big Center Consoles are safe for now.
More info on the V12. The gearbox torpedo steers not the engine.
Slowest web site ever.
12 cylinders. Rotating lower unit. Counter rotating props. 2-speed transmission. A Merc with more moving parts? Uh oh...!
Upside on this engine is 87 octane. Downside, it's the heaviest outboard in history... 1260 lbs!
Their server is being hammered by the news being posted to various boating forums; THT, OSO and S&F.
Wonder what the price difference is versus 2x 300HP's?
Looks like it will have a lot of torque. looking forward to seeing more. Seems like the Valhalla 46 will be the first with this engine which should be a good fit and quite a lot of horsepower for the size.
Price of 3 600's will be about the same as 4 450's. Price is $77,000.
The tests are very impressive and, to me, the most impressive part is this is a real product, not something projected in the future. The tests with 4 on a Formula 550 SSC reaching 69 mph, with 3 on a Whaler Outrage 420 reaching 64 mph, with 3 on a Tiara 48 LS reaching 60 mph, with 4 on a Valhalla V-46 reaching 73.8 mph, with 2 on a Scout 425 reaching 62 mph are impressive as is the improved handling.
Yamaha is believed to be not far behind with their new model.
It is significant that Mercury developed their own engine and did not choose to go with a General Motors engine.
I don’t think GM makes a V12 these days, do they?
"My" engineer (that takes care of our boat on the side) is a Mercury factory guy who keeps a lot of their prototype stuff running as they test etc. He's been spending a lot of time at Lake X where they were testing this motor. Without getting in trouble/disclosing what it was, he had sent me some pics of the Valhalla making 73mph at 6240 rpm... impressive for sure. Time will tell when it comes to reliability from "real world" use, but innovation in the boating industry is always exciting.
For those who want to watch the entire video presentation from Mercury.
Didn't have to be a V12. The point is they took a very different approach to that Seven took.
Bragging rights. Only v12 outboard on the market. Only gas V12 marine park engine actually. Trying to pull 600hp out of a V8 can blend to reliability issues.
And a V12 is inherently smoother.
A great fit for the big center consoles.
Curious if you guys think we'll ever see 4 of these strapped on the back of a redesigned sportfish or perhaps 50ft-ish boats that current use pods?
Now Center Consoles will start going above 65-feet!
So there’s an owner of a Winter Custom 50’ express that may repower from 4x 425 xtos to these.
Yes and a 450 HP is 690 lbs......
so 3-450 hp (1350HP) = 2070 lbs
2-600hp (1200hp)= 2510 lbs
4-450HP (1800 HP)= 2760lbs
3-600HP (1800HP)= 3780 lbs........
Not seeing where this would replace an extra smaller motor or two....or where it fits in since it weighs so much....... Or how a boat not specifically made for this engine will handle with all of that extra weight back there.
More torque too, which raises the question of transom integrity.
Yep especially at low RPM. Heavy handed operators beware !
I’m hoping we will see more large express builds powered by outboards. Given the extra weight of those builds, they certainly can use the extra torque and likely will handle the extra engine weight better.
Would be interested in seeing someone like Mag Bay retool their 42 for these. Would get the same amount of HP as the 1200hp MAN option and may be able to gain a small cabin underneath the cockpit.
