Mercury 2 Stroke V6 History & Development

Welcome back to my channel! Despite the popularity of the Mercury 2 stroke V6, there is not a common place to find a lot of information about them, so I spent hours researching the history and development behind it, scoured forums, books, and compiled what I think is a pretty decent primer on why this engine is worth knowing about. If you learn anything from this, please leave a like/comment if you want to see more of these videos. Happy 4th of July, and Happy MercMonday! Cheers!!

Kids these days will never now the feeling you get from the sound of an ol v6 2 stroke merc screaming down the lake, an it’s a sad feelin to know that.

[@ADDvanced]

Some will! Just gotta give people rides :D

[@tucker934]

Nah man, just herd one that’s supposed to be built, now I wanna v6 2 stroke to put into a creation !

[@terryscogins5575]

💯 exactly right bro!

[@maxsparks5183]

Heck, I mourn the fact that most of you didn’t get to enjoy the growls of the Mark 75 and Mark 78 Tower of Power engines. To me as a child, one of those, especially when backing our little 16 foot Crosby runabout into the river behaved like a living creature, turning to the left and to the right looking this way and that way as it growled backwards into the river. Then she would smoothly and unhesitatingly start forward as dad shifted her seamlessly thru her non-existent (AKA “silent”) neutral. Pure poetry.

[@bradblair1266]

@@maxsparks5183 I’ve seen many sittin around but I’ve only heard a few lol

[@publicdefender77]

This video was awesome man. Huge 2 stoke fan here. I grew up with OMC in my blood. It's sad that BRP discontinued it's Evinrude line and Merc no longer produces a 2 stroke. I feel the general public got dubed into believing 4 strokes were the answer in the outboard industry.

[@ADDvanced]

Yeah, I don't know if Evinrude's claims were true or not, but the fact that snowmobile companies have been able to clean up their 2 strokes and continue selling them makes me think it would be possible. I think part of the issue is that high performance boating has just grown far out of reach of "average" people. A normalish person could have afforded a 200hp Merc and 20' high performance boat, but today, nothing in that category is even really produced. All the high performance stuff is focused for gigantic offshore cats for ultra rich people. I don't know if the market led things this way, or boat companies just had more ROI on larger boats so they focued there, but if the emphasis is placed on small/light/go fast (like snowmobiles) then 2 strokes tech is still pretty relevant.

[@publicdefender77]

@@ADDvanced I was patiently waiting for an outboard with power valves. Brp finally made one in 2019. But as you know too little too late.

[@ADDvanced]

I think it'd be possible, but it just wouldn't sell enough to justify developing it.

[@GT-mn3bx]

@@ADDvanced The sled industry has already passed 2024 C.A.R.B emissions standards. EFI and 100 % biodegradable synthetic oil. Also, they have proven less emissions than 4 stroke sleds on a HP/cc basis. Meaning a 180 HP 2 stroke is cleaner than a larger 180 HP 4 stroke. Especially the 2 stroke turbos.

[@ADDvanced]

@@GT-mn3bx Yeah I'm aware.... I just don't think the people with money to purchase brand new boats (skews pretty old if you look at the data) want something fast/fun/exciting, and they don't want to mess with checking oil levels. If boating became more affordable again, aka, something that younger people, who often want something faster/more exciting, then... maybe we'd see a resurrection? Sure would be interesting to mount a modern 2 stroke snowmobile engine on a midsection of an outboard....

[@horsehead8306]

Oh the memories the sound of that 2.5 bring back. They were an amazing engine. Thanks mate

[@dominicksforza3484]

Those 2.5L Mercury Racing motors were/are the sickest motors ever made. The sound of a single 2.5 is enough the get the hair on your neck stand up... But a pair of them at 7500rpm must be experienced to comprehend the way the sound of those 2stroke Mercury Racing motors to get your adrenaline flowing. Absolutely awesome.

[@henningklaveness7082]

1:27 that clip was recorded just down the road from here in the Hvaler islands. It's a friend of a friend with a pretty crazy rig. I spent the first part of my career in high performance boating, traveled as a mechanic in the F2 world cup, and always dreamed of putting a 2.5 EFI in a Miata. Maybe some day...

I'm just a wknd bass guy but have a '98 triton with a mercury efi 150 2 stroke on it. Def not high performance but man does it bring back so many memories from being a kid. Bunch of guys in Allisons last week pulling back to the landing prepping for race day. Nothing like the sound/smell of the big merc 2 strokes.

Cool subject for a video. But to be fair, I was already in love with the sound and performance of my '92 Black Max 135. It pushes my 19 foot aluminum fishing boat across Lake Huron "very nice". And to those who cry foul about emissions I say "I love the smell of 2 stroke oil in the morning. Smells like.... Merica!" haha Thanks!

[@ADDvanced]

to be fairrrrrrrrrrrr

[@BabyCharlotteschannel]

Yeah for sure, absolutely nothing like the performance and sound, and power to weight of the 2-stroke outboard motors! I can still remember hearing the sounds of the V6 Merc and OMC outboard motors screaming down the lake when I was like 5 or 6 years old! And my first 2 Hydrostream boat's I got rides in, a Viper and a Vegas v-hull!!

Just found your channel a couple days ago and subscribed as I really enjoy the content I have seen so far... I see you are from Wisconsin as one of the first videos I watched was the outboard drags from Fremont of which I used to run the river around there as I'm originally from Sheboygan... I moved to the Branson Missouri area in 2001 to get away from the Wisconsin Winters and I love the large lakes in this area... Since the mid '90s I have had several high performance boats all with the V6 Mercury. Two Concords, two HydroStreams, two STVs and a Rapid Craft Riot..

Me too. Ran a and b hydro in the alki days. C, D, E hydro in the mods Came to fl. Ran a RB koing in the 250 class ( A) was Givin Pete Helston's Mac minnerilli with custom billit crankcase whittled out on his Bridgeport machine in his garage. Ran it on an old 85 Pugh hydro. Which was only designed for around 90 mph. I was running 98 on Banna Lake in Lakeland FL when I ran out of lake she was still pulling. And that was with a 350 ( b) gearcase. We started in 1964 quit in 1969 the alki's Ran mods till 1985. Started back here in fl in 99 I believe and stop in 2005. The only thing different from us Yankees and the rebels in our sport was we ALL got older !!!!! Quite a tribute to outboard boat racing clan. Oh, did a couple of DePue Nats too.

Great video. Love to learn a little more history. I remember the term "loop charge," but it was either forgotten or never saw a drawing of what it actually meant. We owned a 25th anniversary 50 hp Mercury 4 cylinder at one time. They had a nice sound.

[@ADDvanced]

From what I understand there are benefits/drawbacks to both types, loop charged engines run REAL well at Wide open throttle, and not as well at idle/midrange. I could be wrong tho, I'm learning as I go here.

[@nerd1000ify]

Broadly speaking loop charging is a much better strategy than crossflow. Mostly because it does a better job of flushing the exhaust out of the cylinder without mixing it with the fresh charge. Loop charged engines also have better combustion chamber geometry (no deflector on the piston) so they can run higher compression ratios.

[@ADDvanced]

@@nerd1000ify Yup, but the tradeoff is less great at idling/coming off idle. Allegedly. (sick ostrich)
