For all of those that run a 15'-16' aluminum mod-v powered by any of the various brands of 25 hp 2-stroke motors and have replaced the factory or another prop, what model PT or other prop and what pitch are you running. I'd like to know what kind of performance gain, or loss, that you experienced. What pitch & model did you start with and what pitch & model performed the best for you. I am running a 25 hp Yamaha 2-stroke and would like to know what would be the best model of PT (ILB3, REB3, SLC3, SLR3, SRA3, SRN3, SRS3, TLR3) or any other brand & model. And does anyone know if all these models are available to fit a Yamaha? I figure a 12 pitch is the most common and that is the way I'm leaning.
