Table to estimate the shaft diameter

These resulting diameters are for AISI-316 stainless steel, and high strength stainless steel, AISI-329 and V-462, with the correct base supports.

Find the HP of the engine on the table on the left and then look for the RPM on the propeller shaft, (that means the rpm of the engine divided into the gearbox ratio) on the right table. At the crossing point, you will find the shaft diameter in mm on the central table.
