I am trying to figure out what prop to put on my '22 Schiada. It is a '74 so a heavy layup old cruiser with a 502/502 in it and a T-400. The boat has a 1-inch shaft and is a 10-degree V-drive. Where do I start. I am trying to figure out what gears are in it and have come up with the #'s 500.5. Does this mean anything to anyone? As far as I can tell the boat has always been a family skier and has a C-500 Casale V-drive in it. Any guidance would be appreciated. The boat has a 10-7/8 X15 prop on it right now and it is cavitating coming up on plane.
