what is the best size 3 blade prop for a 61fx 2 stoke????????????

Here ya go:. Just substitute for what you're using now. For example, on a three bladed propeller you would drop the diameter and keep the pitch. On a four bladed, you would drop the diameter and the pitch. For instance if you had a two bladed 24-10 propeller and you wanted a three bladed you would use a 22-10 and so on.

thanks for your help
