Has anyone run a Solas 4 blade? I've only found the Solas to fit my Tohatsu, well Michigan Wheel has a 4 blade but only goes up to a 10 pitch. Heck Powertech doesn't even make one, at least that I can find on their website. If you know of a another manufacturer, please let me know. P.S. I'm looking for an aluminum prop. I know some folks had bad experiences with Solas 3 blades, was just curious to see if the 4 blades are different.
