Mercury V-6 Outboard with Custom Pipes

[@maximebeaudoin2135]

Sounds insane but that hole shot though oh my 👌

[@Chadwicky69]

I have another video where it spun it over 10,000 rpms and added some fuel for the hole shot. It sounded a little shitty at idle but picked up a couple tenths of a second to 800', which is almost two boat lengths in a drag race.

[@farmer87yj]

would love to see a vid on the build process on putting those pipe on the block .

[@WisePlagueis]

I love that you kept the "SUPER SILENT SIX" sticker on. Had a good laugh. Sounds gnarly, worth it indeed.

[@Chadwicky69]

Life is too short and not having some fun & laughing our asses off is NOT an option for me! I have since added a sticker, on the front of the boat, that my buddy bought me which says "Loud but Not Fast" haha

[@dennisyoung4631]

Yup. This is what “Mercury *Outboard* Blues” is all about! “…I really NEED a Mercury….”

I like the 1964 Merc stripes

[@miketee2444]

Don't see Dry Stacks much anymore. I doubt they help performance much on mid 80s V6 but the sound and looks are a good enough reason. Even with offshore type exhaust I would tell that motor is right and tight. Those retro stickers are a sweet touch too. Whats it,? Early 80s 2.4 ?

[@Chadwicky69]

That is a 1990 Merc 200 F block and the pipes were designed to be totally reversable. They actually make less power as they were designed to be a bolt on and after all the work it took to get the pipes to function as a bolt on, they still can't collect all of the exhaust coming from the ports, unless we wanted to make them permanent.

[@Chadwicky69]

Either way, the pipes would probably cost horsepower over the standard exhaust chest and 12" mid setup I have. If you could collect 100% you may have a chance to play around with tuning to get closer, but I still doubt it. There wasn't enough time to test the motor on the boat before the pipes were installed. May have to try them after they are taken off and see........

[@miketee2444]

@@Chadwicky69 I still think it's bad ass. One upping a Merc. Engineer isn't easy. Six big cones with on the fly adjustable length will gain something but the cost for a few HP up top is always high. The motor sounds perfect to me as is.

[@ct1762]

@@Chadwicky69 less backpressure maybe? its like those swedes that put that V8 Evinrude in a car and where very dissapointed to find it had no balls down low. im guessing for a similar reason.

[@oneninerniner3427]

Need expansion chambers-tune pipes. But that would be a bunch of stuff hanging out the back!

Damn it sounds good

[@GlenB1963]

F#ck yeah baby. Sounds like about 9000 rpm.❤

[@Chadwicky69]

I would have to look at the data, but I believe it was 9200ish. The other vid I uploaded after an intake swap and a proper tune ran up to almost 10,200. I raced it last weekend in better air and a better tune that netted just under 10,400 plus .03 sec faster ET to 800'

[@UltraMagaFan2]

Why does it say 2.5 horsepower in the caption? They’re 2.5 liter engines that make 240 horsepower. Anyways, I love the boat. That thing is badass.

[@Chadwicky69]

I don't know what caption you are talking about.? I didn't type anything like that, as far as I can remember, unless I was drunk lol. It is a 200hp, not a 240hp. I don't know of any 2.5 Merc outboard that was rated @ 240 but let me know if they did. Btw, nice sig pic!

[@UltraMagaFan2]

⁠​⁠@@Chadwicky69 I commented this on a KZbin short. KZbin glitched and put it on your video for some stupid reason. And the 240 horsepower 2.5 I was talking about was modified. It was a built racing engine that made 240 horsepower. It was on a Phantom 25.

[@Chadwicky69]

@@UltraMagaFan2 Gotcha

[@jakeness543]

that is awesome but if you got a huge battle wake can’t that hydro lock the engine

[@Chadwicky69]

If you are not moving and a bunch of water splashes into the pipes, it could easily get into the bottom 4 cyls and cause it to hydrolock but that would most likely happen if you were backing up or sitting still. It can be taken apart so the water could be drained and cleaned out if it wasn't running hard when it happened. Put it back together and run it for a while to make sure nothing inside the motor is left to make it rust. They actually have plenty of clearance if you leave it trimmed up all the way.....steep boat ramps is what I worry about!

[@jonnun7713]

man! that is way too cool!!!

[@daffyduck9901]

Now that's what I'm talkin about 🤙

[@norwajjohnson8726]

sorry but why are there only 2 mufflers instead of 6? v6 engine🤔

[@Chadwicky69]

This was a fun experiment and no power gains were expected. Running two pipes took away some bottom end torque and high end hp but work fairly well in the mid-range. I wanted to run 6 separate pipes but they would produce even less power as each side uses the tuned exhaust from the 3 cyls work with each other. That's why "stacker" pipes are commonly put in pairs or triples......not to mention the logistics were pretty much an impossibility anyway.

[@steveknoche9557]

Just went you think that motor was at max rpm it jumps another octave.

[@Chadwicky69]

I have another video where it spun it over 10,000 rpms, instead of 9100 rpms, and added some fuel for the hole shot. It sounded a little shitty at idle but picked up a couple tenths of a second to 800', which is almost two boat lengths in a drag race.

[@Cojiii1959]

I’ve got a 2 stroke optimax and can’t stand it. Sounds like a friggen chain saw. Going to a mercury racing 400V10.

[@Chadwicky69]

Well then.....this video is not for you brother.

[@michaeljohnson-pw6gh]

How fast where you going ????

[@Chadwicky69]

Around 90 mph....This was a test for the drag race class that I was setting the boat up for. It would go a lot faster but I am trying to get as much acceleration out of the rig for the 800 foot course. Motor spun 10,190 rpms with a different prop in my other video, while still too rich above 9500. Still have a bit of tuning to do haha
