Need the boat size and type.Do you know the gear ratio? Sometimes visible on the out drive.
Prop selection will also depend on your typical load and activities.
Probably going to be pricey. You may want to find a dealer that will let you try some props with the understanding you are buying from them.
Usually requires a sizable deposit.
