Propeller Shaft taper on the engine end

Double tapered shafts are common on many tournament ski boats. Our standard shaft is only tapered at one end and fits into a non-tapered flange with key and set screws. Unfortunatly, manufacturers of of the double tapered shafts have not used a common standard for the taper. In order for us to match the shaft you have, we need to know the diameter of the "minor dimension" of the taper. Please specify minor dimension of the engine end taper when placing an order. There is an additional charge for tapering the engine end; see item 90-760. There is no charge for the standard taper on the prop end.
