Merc outboard question
What is the largest cylinder engine and HP of a merc outboard? anyone know?
And this can include prototypes.
This is a serious question guys as I heard about something but cant reveal any details at this time.
The largest horsepower Merc I have seen was a joint effort between Merc and Marine Turbine. That outboard was reported to have 450+ HP. The largest conventional reciprocating engine is the 3.0l V6 at this time. This displacement is available in the Optimax series. I think they may have made a 3.4l engine, but my memory is foggy.
ETA- You must be in Fon Du Lac..??
Oshkosh actually, have looked on their website. The verado series is nice but no hints as to anything really big like 6+ in an inline motor.
The Verado's are nice engines. I-6 supercharged. I installed a few on Triton center console boats this spring. They run smooth and very quiet. They are also pretty heavy. The Verado wouldn't be my choice for a bass boat. I'll take an old 2 stroke carbureted Black Max for a bass boat, maybe an EFI (not DFI).
ETA–– OMC used to make a V-8 2-stroke outboard. I worked on one of those a couple years ago. Man did that thing sound wicked. The boat's name was "The Hellion" and it sure was.
This is now the largest outboard....You can thank me later :)
I was thinking of something closer to an inline 12 cyl monster?
WOW! That 7 Marine V-8 is impressive. Definately suited for offshore boats. I still want a turbine though. The turbine powering the Mercury experimental outboard only weighs 140 pounds. There used to be a video of the turbine on a bass boat somewhere. Sounds wicked! I wish 7-Marine would have cut the music and let the engine sound come through for a bit. Other than the turbine, nothing sounds like a V-6 2 stroker at 6200 RPM's.
KB...you look like Ron White in that picture...
EDIT: What kind of lower units are on those? They don't look stock...but then, i've never seen a 300hp out board either...
Those are Mercury "Sportmaster" gearcases. They come stock on the 300X outboards. By the way...who is Ron White?

Not sure if serious...
Largest production merc right now is the 350 verado! I believe it only comes in 25 and 30 inch lower unit for offshore rigs. Yamaha also has a 350 4-stroke
