opinion on a phase kit yamaha or a 300xs merc? If anyone knows a lot about hydro-tec performance upgrades for both hammer and merc please explain which is the top dog.... hydro-tec yamaha or HT Mercury.... also whether to hop up a 250 or go straight to the 300?
My opinion- start with the 300XS. It's already got substantial improvements, including a factory-designed tuner, stroker crank, and it's "dependably" putting out the horsepower without "modification".
