I have a 98 Sprint 296 Pro (19.5ft bass boat) with 91 Johnson 200
The prop on the boat is stock Johnson 3 blade stainless 19P (13.25" I think)
When I took it out for WOT the motor revs past 6k @ 53 mph, I ran it to 6200 and it was still climbing steadily when I let out of it for fear of damaging...
