I would like to know the best prop for this outboard. Mercury 40hp ELPTEFI.
I would like more speed.

We need 2 questions answered first...
1, what boat do you have?
2, what is the main use going to be...fishing, top-end, pulling tubes, etc..

wouldn't hurt to know your present max rpm, prop and speed as well.

I guess this to be a transplant engine? (new to you)
That's a lot of boat for a 40hp.
Do you have it set up and running? If so, as mentioned above, we really need an rpm figure with a known prop.
