On the 14' skiff I'm finishing up (The Fidder), I've got a 1987 Mariner 20 hp that's pushing her along nicely. It's got the original aluminum 3-blade prop and I want to upgrade to Stainless. I don't have the exact size in front of me, I know it's a 10-spine prop. One question is, will a 4-blade prop reduce torque steer (it's a tiller-steer motor)? Toss in your opinions here on my best options.. thx.
