Would like to know what size (diameter and pitch) propeller is best suited for the Cape Dory 36'/40' with a Perkins 4-108 Diesel engine

The prop that was on our CD36 when we still had the leaky Perkins 4-108 was a 15 R 14. The transmission was a Hurth marked HBW150-2R iA=1,88 iB=1,95 (I assume that was a 1.88 ratio forward and 1.95 reverse)
