I'm selling my Rev 4 (Revolution4) Mercury prop. It's just a little big for my current boat, it's got a hub in it and I'll include this in the deal. I tried it twice, but it was too much blade for my heavier boat. It works great getting on plane, towing, skiing was improved too. It's in excellent condition and weighs 16. Lbs shipped from 32940 in Central FL. I'm asking $275/OBO plus shipping. Please call Dean at 321-890-2394 (EST) it's a 14.5" x 21" Pitch 15 Spline for Alpha/Bravo drives.
