Location: Elk River, Minnesota | Hi Dave,
If the diameter is too small, the prop will spin more freely as well... 14 x 19 is just a standard size... If you go to the suzuki outboard website, you can download the different prop sizes that will fit your motor, but keep in mind these are just suzuki brand props. There are many aftermarket props out there that are designed to fit your motor as well...in fact, aftermarket props are in most cases cheaper than OEM props.
When I looked at the chart, a 14" diameter prop is what the majority of the props are with a 13-1/2 x 15 as the smallest size.
So..knowing the diameter should be around 14, I would say a 14 x 19 would be a good start... Your motor is going to have a bunch of power with the gear ratio...
