Piston coatings

[Pro-pulsion]

Of course when thinking in hindsight, just abandon the whole Polaris pwc engine thing...they couldn't make one worth beans anyway and probably why now they don't lol. I've never seen an engine be able to throw a crank out of phase so easily as I have a Polaris...yeesh :/

I’m not sure. I was only saying what Dan Lamey told me

Nikasil does not rust and its hard enough to need diamond hones to finish it, not sure what more you would want in a cylinder coating
