    Do you know your current size and top rpms fully loaded? A prop shop can tell you exactly what size you should need.

    My boat at the moment is a bit under propped without it being full throttle I hit over 2450 so just trying to see if anyone has swapped to 4 blades to get a starting point

    Try calling Viking, they might know what size your boat came with and you can compare that to the size you have to find out what should be on there. Are there any large prop shops in your area, they may have a used set you could try to get a base point and go from there.
