Repowers do not have any payback so spending less is always wise.

Even with all your details, saving 3K is compelling.

Props:

Suzuki DF30a - Suzuki 9.25x11” pitch

Tohatsu 40 -

From a post back in '18
With a WOT of 5850, 1.85 gear ratio, target speed of 32 (based on 40hp), 5% slip, the prop calculator is showing 11" of pitch. In stainless steel, that is part # PT4050P11
