Hello! I have a 40hp twin mercury single carb and I was wonder if I can make it a twin carb and would it be a benefit? The 40/50/55/60 3 cyl 3 carb mercury are the same except one more cylinder. If I bought a intake manifold and reed cage from the 3 cyl and chopped off one of the cyl intake I would be able to mount 2 60hp carbs on my motor. Has anybody ever done this and is it a benefit ?
