I kicking around the idea of upgrading to a 40 or 50 H.P. for my 17' Alum. boat
Tiller handle model.

I know the 4 stroke will get a little better gas mileage but its hard for me to get away from the 2 stroke, sense that is all I have every been around.

Is the 4 stroke that much better on gas to put up with its larger size?

Give me some input on your experience with either one.
