Cons of two-strokes being they're not allowed on the Grand. Does anyone know if that is the only place they're banned around the desert west?
I would steer away from 4-strokes. The pros are they're much quieter and use a lot less fuel. The cons are they weigh 50% more but most importantly they are very fickle as to how they are stored on your boat. If you store them incorrectly the oil from the crank case fills the cylinder(s). Fixable on the riv but difficult to accomplish without contaminating the water or beach
