I'll be experimenting before launch this season. I'm going to strip the props, rudders, trim tabs, and struts. Then prime and paint with Pettit Black Widow. It's cheaper than Propspeed, should be easier to apply, has some antifouling properties, but is also a very slippery paint. We'll find out how it holds up at the end of the season, but my hope is that it should hold up decently (maybe not quite as well as Propspeed) and should be enough to keep the props and other running gear clean up here in fresh water.

Ideally, I'll pick up a little cruise speed from having less drag on the high water flow surfaces compared to bare props and ablative paint on struts, rudders, and trim tabs. At a 17 - 18 kt cruise, I figure it certainly can't hurt and is likely to make at least a small difference.
