I need a prop for a Volvo 2003T with a drive MS2B with a 2.4 reduction, have maximum diameter available of 14".
I will need the length and weigh of the sail boat to make a recommendation.
Typically you need .10 of the diameter of the prop between the top of the blade and the bottom of the boat
or strut. So if you swing a 14” prop you would need something like 15.5” of actual room.
Also typically you want to swing the biggest diameter with the shallowest pitch for a sail boat.
