Got a 94' 40Hp Yamaha I want to give a little more pep to. Will Boyseen reeds do it and would it be noticable? Are they worth it? What are some pros and cons? Are they fairly easy to install? I'm mech. inclined and could do it except for a carb. adjustment if necc. Carbs. intimidate me for some reason. Also, any drawbacks to using bigger carbs. on mine? Say changing mine and putting 50-60Hp carbs. on.
