R27 Yanmar - Stainless Steel Motor Mounts?

Replacing my mounts - the current replacement options are not stainless. Anyone have a stainless options out there?

I replaced our mounts a couple of years ago. The bases on the rear mounts were pretty rusty. Tried to find some rust resistant alternatives but no luck. I ended up making half inch thick fiberglass spacers to lift the mounts up off of the stringers and away from the water that tends to pool there. I also applied zinc rich primer and Yanmar paint to the replacement mounts. Three years and no sign of any corrosion. I did a write up on here, search for it and get part numbers and details.

Thanks, I did get those part numbers. Appreciate the insight.
