I drove a 21' tunnel hull years ago with an Evo Stage 5 tuned Johnson/Evinrude V8 that made 440hp at the prop. The sound from a two stroke V8 at full song makes the hairs on your neck stand up

This needs to go into a Trabant, mid mounted, ASAP.

I sent that video to my Trabant-owning buddy. Still waiting for the results.

Off to look for ITB's(from a boat, don't know why I never thought to look there) that will flow enough for one of my projects...

Merc used to sell a racing engine called the "Mod VP" that ran on Cam2 fuel and had zero warranty. Sounded a lot like that. The engines were about 2/3 the cost of a normal merc engine.

That's a vertical mount engine. Can it be run in a horizontal orientation? I guess oiling would not be a problem, would it?

Awesome!,notice how the lack of a flywheel and tq barely move the stand with throttle blips

How would you hook a trans up to something like that?.

In reply to cwh:

Its a 2 stroke, if the carbs are set up right it will run in any orientation.

I have my doubts its set up to handle thrust loading a clutch will give you, so you'd have to to run it divorced. That is, run the flywheel/clutch assembly in its own pair of tapered roller bearings and drive it with a slip yoke.

No oiling problems, but would definitely take some reengineer of the intake system.

It looks like a typical OMC outboard configuration with carbs mounted where the oil pan would be on a 4 stroke V engine.

Mount it upside down, or on its side, webers as needed.

I've got a snowmobile that does that for reverse. Skidoo calls is RER.

With it idling, you push the button for reverse and the engine slows down and then starts spinning backwards. To go back to forward you push the button and it repeats the process.

I'm not certain, but I believe it changes the timing to slow the engine until it makes the engine change direction. There's no electric starter on the sled.

In reply to jstand:

IIRC there's some old microcar that did this, it was accomplished with a second set of points that you switched to to alter the timing, but you were supposed to shut it down first and use the reversible starter.

Hmm - an engine that produces copious amounts of oil smoke, marvellous noise but uses vast amounts of fuel (that outboard is apparently a champion guzzler)? I think I prefer my old Jaguar Mk 9 ('Moby Barge') or my current old Lamborghini - both are/were very good and turning large quantities of fuel into wonderful noises and a bit of smoke (though not anywhere near what a 2 stroke puts out).

Neat engines though - couldn't find a weight for them....

A well tuned two stroke emits practically no smoke, and only uses a large amount of fuel because it makes a lot of power. Modern two stroke sled motors rival the four strokes in power and fuel economy, but are far lighter.
