Have you ran it yet with new engines? I would run it first and see how the rpm/speed/ cruise looks compared to the earlier combination. Then you have the data to make a real guess...Which 41' is it? side by side or staggered, full cuddy? Most of them like a bigger diameter prop, some like 5 blades... it really depends on the set up --- trial and error.

What's your drive height?
for reference: I am running a similar setup on #5 drives, old Top Gun side by side, should be pretty close. Drive setups have been -1.0" and 0.0" from bottom spinning out
18" x 30" props - better to get on plane and good cruise around 60mph @ 3600 RPM, 70mph @ 4000 RPM?
18" x 32" props - poor to get on plane excellent cruise around 65mph @ 3600 RPM, 75mph @ 4000 RPM?
If your propshaft centerline is below the bottom, you can run 17" or 17.5" props
