Now were getting somewhere!

I'm not entirely sure that it's not just a clever workaround on how emissions are generally measured. If you have carbon based petrol, mixed with carbon based oil and it's burning in the atmosphere at the same temperature you're going to get the same molecules in the exhaust. Maybe the boron changes how these molecules bind so that standard measurements see less of what they're designed to look for and don't see what's now being produced?
Ie, if you can change the combustion to produce less pm10 particulate pollution by creating much more pm2.5 then you could claim such a substance massively reduces pm10 particulate pollution.
Most 2 stroke outboards pump the bulk of their exhaust and excess oil into the water. Oil actually biodegrades really quickly in water. Bacteria feasts on it. When we think back to that well spill in the Gulf of Mexico most of the clean up happened naturally as the oil was rapidly digested at sea. Particulates are less of an issue as these are pumped into the water. The real environmental damage tends to be what's left behind in the form of toxic elements such as heavy metals.
If this oil is soluble and rich in boron then I'm not entirely sure you'd want it used in outboards? The excess oil that isn't burned would dissolve into the water body rather than being naturally biodegraded and the high levels of boron strikes me as being quite nasty if it built up in an enclosed water body.

Very interesting reading. I'm not very good with chemistry myself, but you could be right. I'm not the right person to judge. Regardless, if boron is potentially worse for the environment than the regular stuff it wouldn't be worth using it.

Well, they have this product that is specifically for oil injected engines and they mention leisure boats as an application. They also mention leisure boats for the concentrate version of the product.

But you are right, normal 2-stroke oil and outboard oil differ. According to Triboron their product works for both.
I read what was available on Triboron on Swedish forums, which is very little. Users seems to report that their outboards run better at idle and that smoke and smell is practically gone. One user reports that he lost a little top speed. Which is worrisome since that could possibly indicate more friction and not less. But it could also be a fluke.
I saw a video on Youtube where a user ran his very old outboard, idling for 2 hours before it was shut off. That is very impressive for any 2-stroke. Usually they foul up long before that.
Well, I'm not sure what to make of all this. But I will try regular 2-stroke oil next to see if that affects top speed or idling.
