Thank you for deep dive into these odd ball outboards. Im a marine engine mechanic and had never seen these omc rotary outboards.

Someone said omc was a power house 😂😂😂😂 Merc ruled racing. Omc stands for outdated motorized contraption.

Hey Liam, I saw in a previous comment you have the schematics and parts list for all the wankels would you mind sending me one for the 303(km914) and the 295(km24) I believe

Thank you so much, for puttings this piece together!

Great video dude! Very informative. I got a hold of one in San Antonio Texas all original only four original hours on it. Tank carburetor exhaust all the bells and whistles and three original booklets.

I thoroughly enjoyed this video

lol 10600 rpm. Would've loved to hear that. GREAT video man!

This should so be a movie 🎥 with Will Ferrell and Ben Stiller 😂

I worked at OMC & BRP for 47years. As an expediter was responsible for collecting and scrapping all the rotors and engines at the Plant 1 assembly area and machine shop floor. One thing several of us old time OMC guys wonder is what would the Ficht injection been able to do on the rotary.

The best you can do with this KM-3 engine from lawn mower would be carving side seal grooves to have it in both sides, with the original arrangement, only if the rotor side with no seals faces down, can a good CR be achieved.

Great video! Liked all the racing competition shots and review of the results. Knew OMC and Mercury were tough competitors against each other, but didn't know about the potential sabotage and special racing rules to benefit one side. ONC's rotary engines power to weight ratio is fantastic, but high bsfc numbers don't portend well for economical fuel applications.

Viedeo stopped without starting the engine !!!?

So cool. Those were the days, for sure

THE ETERNAL GREAT OMC

Hey man, not to experienced with these. Reassembling my km3 and was wondering if there is any timing of the rotor to the eccentric shaft when it goes in? Or does it not matter? 😅

Thanks for putting this together. Very cool and informative video.

Paul Moller...genius grant to produce the "Moller Merlin" flying car that never came about...and destroyed the potential of the rotary outboard. OMC bought out even though etec actually had potential for those of us trying to get light outboards with great power for small boats.

This video is amazing! I have come back to it several times. The information you have provided is invaluable. Thank you!

*Just an FYI:* Rob Dahm of the 4 rotor street car notoriety, has just taken on a project with a 12 rotor N/A powerplant designed by Tyson Garvin to fit in essentially the same space as a big block Chevy, with the intent of making a longer lasting, higher output, marine type powerplant. So far, Garvin has only run the engine with a large 4 bbl. carburetor, which limits it to 2000-2500 rpm., but even at that, it produced phenomenal horsepower and torque. Rob Dahm is attempting to set it up with programmable EFI and ignition, but there are some internal issues that need to be worked out before it can be tested to it's full potential. It will be an exciting project nonetheless, so all you rotary fans might want to check out Rob's channel for updates.😉👍

How did you find the engine ? I’ve been trying to find one

Hi mate Can i please get the part numbers for the apex, side and corner seals? Thanks

Hello, i want to buy such a motor. Does anyone know where i could find one? I want to engine swap my "project moped" i would love to do that

UUUUÄÄÄÄHH !!!

Hello, I’m checking in to see what supplier you got those OEM seals + parts from?

I bought one of those new and have it mounted on a 18inch Lawn Boy deck. Very few hours on it due the junk Italian magneto. The ignition coil has the condenser built into it and it's kaput. When I have the time, I think a Tecumseh/ Phelon ignition coil might work in this application with the external condenser, to restore a hot spark.

Very interesting and well done!

Awesome video loved it

All the motor were junk

Very informative video Liam. Do you have a PDF if the manual available? Cheers.

Some anaerobic sealant between the case parts might help with sealing it. That's what they use for 2-stroke outboard engines.

Great video I love driving a good running rotary.

This is amazing I have heard about the omc rotary before and how it went into race boats but this is extremely in-depth and really cool what happened in the 70's.

Such an awesome video. I've been a boaty my whole life of 59 years, and this is the first time that I heard of the OMC rotary. Trust a rival to F up their progress.

Masterpiece 👌

Awesome! Thank you, I always wondered what happened to this program.

my boats

KM 914 is 303cc the rotor and housing are 70mm wide ( 2mm wider than the 294cc Km24 and KC27 variants )

Mercury played dirty!

Johnson and evinrude were the standard back in the day, its ashamed they are gone

UÄÄ!!!

Bombardier drove OMC into the ground. They started tanking and lost their single isle aircraft and I knew it was going to tank

Amazing documentary! I love rotaries but I didn’t even know there was such a big market for these engines back then…these engine was insane!

Interesting story, I didn't know.

What a great video !!

It’s pronounced Vankel not Wankel.

Hay Liam Great work! I love the rotary motor but more important you did a great job putting this video together and narrating. I believe there’s definitely a future in this for you.

I wonder if Shweinfurt translates as pig fart?

Incredible Video Brother!! Thank you..a 30 year marine ye Technician, Johnrude Afficianado and Rotary Devotee. FUCK MERCURY. FUCK BRP FOR SELLING OUT TOO

Thanks for doing this. I remember reading an article about an experimental rotary outboard engine back when I was in high school. I remembered it as a Mercury but maybe it was the Johnson. I do remember one quote from the driver being scared of the motor because he never got it to stop gaining rpm and propelling the boat faster than he could handle.

Great now i want one of these outboards
