Wanting know if these are interchangeable and what would be the difference in performance.

what do you have on the boat now?
what boat, what size, what weight, what motor, what drive ratio

volvo does not list pitches on their duo-prop drives, they list series with a number. the lower the number, the lower the pitch. the higher the number the higher the pitch.

so stick with the number you have. there are some series that are interchangeable (stainless vs aluminum) Type D is aluminum, Type F is stainless. if you are upgrading from a D to F, you do a straight swap.

Thanks I went with a apples for apples swap.
