2121 SJ is here! Orig: Is 2020 Really the Last Year of the Superjet? A call to Action.

[Kawy750]

Trump!!? Obama!? God!??

This conversation took a sharper turn than any superjet i’ve ever ridden!

 

[E350]

Kawy750: Don't forget Ocasio and her "Green New Steal"

And every Democrat presidential contender has signed onto it.

It does not just ban 2-strokes, it bans all combustion engines.

Are you ready for a sail powered Swedish child approved Super Jet?

Don't think it can happen? Australia banned all sales of new 2-stroke engines in watercraft. Don't think California won't do it too? You don't know CARB.

I read this thread's title. I honored chixwithtrix by taking her thread seriously.

My suggested "Call to Action" is to preserve our Freedom including the freedom to 2-stroke Super Jet ski by voting for Trump and for corrupt free market RINO Republicans instead of central planning control corrupt Communist-Environmental wacko Democrats.

What is your suggested "Call to Action?"

Edit: To include underlined material above.

 

[KMN]

Holy poop dude, stay on target. Keep this about fun stuff, lay off the politics and religious bs.

Superjets for life.

 

[E350]

KMN: Got it.

I will honor your request to stop talking about politics and religious bs.

What is your suggested "Call to Action?"

How do you propose to keep "Superjets for life"?

 

[joelake]

What's this Australia banned all 2 stroke engines B.S?

I will go out today and buy a new mx bike, a lawn mower, a water pump and a generator. All 2 stroke.

I got a shed full of 2 strokes, and will have for decades to come

 

[E350]

joelake and others please accept my apologies if I am wrong.

Am I wrong?

Isn't the issue whether you can still buy a new Super Jet in Australia?

Can you?

I revised my statement to read: "Australia banned all sales of new 2-stroke engines in watercraft."

See:

Warning against stockpiling old two-stroke outboards

Industry warns importers and dealers against stockpiling carbie two-stroke outboards ahead of 2019 sales ban

After July 1, 2019, any carbie outboards in stock at dealers or importers must be destroyed or re-exported. Those engines in operation and privately owned are still OK to use. The regulations apply to the sale of new engines only.

Keep in mind the ban is for carbed 2-stroke outboards. I am pretty sure all of us know if there is a new superjet it would be 4-stroke.
Besides, banning carbed 2-stroke PWC's is nothing new here in the states either regardless what party is in office.

 

[OtherDonnieGuy]

Real question... why doesn't Yamaha just come out with an all-new model for a 4 stroke standup, and leave the superjet alone? Then we can still have both!

 

[turboless terry]

Maybe that was why there was talk of krash coming with efi for 2020 models.

 

[E350]

Maybe that was why there was talk of krash coming with efi for 2020 models.

What is going on with that?

I don't see how direct injection into the cylinder could oil the crank bearings.

In fact, I don't see how indirect injection into the crank case could sufficiently oil the crank bearings.

Based on my limited knowledge, it would seem hard to beat the crank bearing lubricating effect of the fuel/oil mixture being fogged by the venturi of air rushing into the carburetor and then sucked into the crank case...

Anyone know more?

Back to saving the Super Jet.

Seadoo's and Polaris use to have Fuel Injected skis. The oil enters through ports in the throttle bodies just like they do on 2 strokes with oil injection.

 

[E350]

Oh, I get it, so no premix? But rather parallel separate injectors with separate injection events?

One injection of fuel. Another injection of oil?

Both "indirectly" injected. (I.e., into the crank case, not into the cylinder?)

Gee, what could go wrong?

 

[SXIPro]

My call to action is to give up on this thread.....

I was watching a video about making 2 strokes Direct Injection, and the guy had a really good point. At what point is it no longer a real 2 stroke?...

When you start adding injectors, pumps, and control systems, you have all these other cycles going on outside of the normal 2 stroke.

 

[Quinc]

Now that we are off topic. Interesting read on Honda's clean two stroke. https://dirtbikemagazine.com/exp-2-a-clean-two-stroke-from-honda-two-stroke-tuesday/


Another idea is for us all to start running the smokeless two stroke oil and "look" cleaner to the public. Along with some "Clean 2-Stroke Technology" stickers in green for the skis.

 

[Big Kahuna]

I had forgotten about Hondas fuel injection system. Thinking Polaris or Seadoo boug the technology from Honda.

Don't forget KTM, they now have brand new injected 2-stroke dirt bikes.

Or the E-tec outboards, the fuel injected 2-strokes have been a common thing since the early 2000's.

Seadoo was Orbital and Polaris and Kawasaki were Ficht.

No issues with crank bearings since you inject a little oil directly into the crankcase amd they don't need that much.

There are both types, Direct Injection or port injection and they have all been really reliable since the early 2000's.

But, it's pretty clear that anything new from Yamaha at this point is just a wish and a dream.

Dual Stage Injection

 

[bird]

I can't wait for an electric jet ski. If done right all of the following will be possible.

1. Sealed engine compartment.

a. Endless submarine ability​

b. No air needed, it's electric​

c. No water​

d. No salt or contaminates​

3. Locally sourced energy.

a. Electricity is produced by multiple sources(hydro, wind, solar, and natural gas), and becoming more peer to peer(Solar City).​

4. Battery packs that last 20-30 minutes.

a. No need for hours of run time on a standup, just get two-three packs that are easily swap-able like R/C Car, boats, and planes.​

b. Fast charging(less than hour to get 20 runtime).​

5. Instant torque!
6. Much Higher RPM!

10k on a electric motor is nothing, try 50k like R/C cars ​

7. Ultra reliable

a. Get swallowed in the surf? No need to start the engine. Just go!​

b. No water in the engine bay, no need for scuppers, bilge pumps, etc.​

8. Low Noise

a. We can ride all those places we couldn't before.​

9. No polluting

a. We can ride all those places we couldn't before.​

Anything else I can't think of?
