2 stroke ?

[pcrussell50]

Speak for yourself. I'm a member of the general public and I would love a new V6 2-stroke. We just weren't given any choice.

we still had carby two strokes until 2019 or so in Australia. It was like a science fiction speculative fiction… what America would have looked like if carb two strokes could still be bought new.

of course, we know you can still see new carb two strokes in third world countries too.

Seam's silly to me for .03 percent of pollution in the WORLD. 2 strokes are easy to take care of and to fix. Try to rebuild a computer controlled any thing after it's been in salt water.

but dfi 2 strokes meet current regulations and far exceed co requirments

[David - WI]

The "new" EPA is currently wiping out thousands of regulations. We'll see iif anybody wants the two-stroke portion of the outboard market without all the crippling regulations.

[keith scotton]

DFI outboards are great are cleaner than 4 strokes. where are the catalitic converters that they where suppost to have on 4 strokes to get rid of nitrogen oxides. Make it simple I do not need it to operate the trim or have some strange steering assist. Let the computer control the thing that needs to not every thing. People should learn how to operate a boat not have one just because they can. Just look at the pictures and video's of the People that don't have a clue. Most people do not need a 50 mph boat much less one that will run 100 mph.

There are no current regulations. Lee Zeldon just (EPA chair) just squashed all green-tard regulations for gas, diesel and LP gas restrictions.

Outboards have always been about 50 years behind motorcycle's when it comes to two stroke technology. Might be an exciting time for hi-powered /mid size / light weight models to hit the market.

I don't think you'll see any big 10 or 12 cylinder 2-strokes to push the whale's around, but you never know.

Can you point out the DFI 2 stroke bikes for me?

The Japanese clearly have zero technology for cleaning up 2 strokes, looks like it was left to a German and an Australia to clean up 2 strokes

I do agree lightweight engines and small gearboxes have a market, BRP got tech for lightweight 2 stroke and 4 strokes.

Pretty sure he was referring to hp to cc ratio. For example, 80cc (KX80) made 20-27 hp. Figure that ratio out on a 2.5. RR

bikes got room for chambers and got gears...
how about a BRP 800cc sled with 165 hp

[JPEROG]

I have had both, still do have both in the snowmobiles 2025's 850 turbo two strokes (180 hp), 850 non turbo two strokes (165 hp), and 998 & 900 four stroke turbos 180 hp stock up to 350 on pump fuel with tune and minor changes, and up to 600hp (on race fuel and heavily modded motor). I ride the 4 strokes every time unless we are on mountain sleds. I also prefer my 430 4 stroke BETA dirt bike over a 300 2 stroke for almost all conditions. Outboards, I love the 450 on my LCB and it is stupid fast with torque to pull the weight (still fast with people) which the two strokes never did well. I might be the odd man out but I really am happy with how many trouble free hours we have logged in the last 4 years and never had to worry about high octane fuel availability.

Still, displacement, weight, and cost goes to the two-,stroke. When money is not an issue, you can buy more 4- stroke performance than the 2-stroke guy can afford... but you'll always get more performance/dollar with the two-stroke. Equal displacement, weight, and cost... 2-strokes win every time.

I'm sure they have tech locked away that they never got the chance to put before the public eye that would even have "ole four stroke Joe" frothing at the mouth ...

[pcrussell50]

Obviously two stroke has it all over four stroke for compactness, weight and power for a given displacement.

BUT

Certain apps are more tolerant of extra weight, extra size, and extra complexity. In those spaces, four stroke will be fine.

Starting at one extreme: Aviation is the ultimate app that is not tolerant of ANY of those things. This is why we have jet engines, even though there is nothing on the planet that guzzles fuel more than a gas turbine. Minimizing size, weight and complexity is so important in aviation that the insane fuel consumption is worth it. Boating seems to be somewhere in between: Planing hull boating is less demanding than flying, but way more demanding than rolling on hard surfaces. In a boat, you can build it bigger to float heavier weights and you'll be good to go. Also in the USA at least, people here have an unusually high tolerance for going into very high levels of discretionary debt, so the "big, new, and expensive" formula works. It obviously doesn't work everywhere though, because the engine makers still make carbureted two strokes in places where the regulations allow, and money doesn't flow quite as freely.

Its all about usability, dependability, availability, and performance. Why would anyone tow with a gas motor when you can have diesel. If two strokes were so appealing for anything other then drag racing, you would see them everywhere. Go to a run and see all of the guys loving the new stuff on small boats "its not just me"--if the two strokes did anything better, guys would have them. Its not an affordability issue, its a matter of having the best performance available. I personally own both current versions of dirt bikes, boats, snowmobiles, and water craft. Other then the yamaha 701 stand up, I will jump on the four stroke version every time.

The small performance boats and water calm enough to enjoy them are so rare that market has dissipated.

Just curious, why would you spend that much money on such known inferior products ?

Trump has been in office for two months. It took a month to get his cabinet together ... Oh I forgot , you got all the pre release 2028 models from every mfg .. as well as all the R+D stuff that never made it into production ..
