The following formula can be used in computing the shaft diameters.

D = Shaft diameter, inches 
P = Shaft horsepower
S.F. = Safety Factor*
St = Yield Strength, torsional shear, lbs/inch squared
N = Shaft speed, RPM
 

BoatsPleasure boats intended for heavy service and all diesel and gas turbine pleasure boats should consider safety factors of at least 5. Commercial boats and high performance crafts should consider higher safety factors of 10 or better. 

* Generally, safety factors of 2 are considered adequate for boats intended for light pleasure service. For more severe service — such as racing craft, workboats, diesel powered and gas turbine powered boats — higher design coefficients should be chosen, based on experience.
