I own a 2008 215CC Tahoe with a Mercury Optimax 225 DFI. When I bought the boat it had a 4 blade 23 pitch stainless prop. The boat struggled to get on plane with more than two people on board. I just switched to this black max 3 blade 21 pitch and now I am leaping out of the water and achieving WOT RPM’s! Love it

Perfect fit on my Mercruiser 3.0 with the Alpha 1 Gen 2 (135 HP) outdrive. It’s a little more expensive than what my local boat shop sells but they were out of stock and I was on my own. Also, instructions are a bit confusing for the non-mechanic, but if you’re familiar with changing a prop, you’re going to be ok.

Smoother than my chipped original. Picked up 2mph or so, easy install
