I recently switched from a 3 blade aluminum 14.25 x 21 to a stainless 14.125 X 19 Boat has a 260 V8 / Alpha 1 - it's a Sea Ray Seville 210 MC
Aluminum 3 blade prop - 1,000 rpm (no wake speed) 3.3 mph 3,500 rpm - 25 mph and topped out 4,400 rpm 40 mph - Very slow out of the hole (I'm guessing 10+ seconds to get on plane)
Stainless 4 blade prop - 1,000 rpm (no wake speed) 4.6 mph 3,300 rpm - 25 mph and topped out 4,500 rpm 41 mph - Jumps out of the hole (I'm guessing 5 seconds to get on plane)
All speeds are per the GPS
All in all I am EXTREMELY happy with making this swap, It's like I have a new boat. - I see no down side in this case. I know this will not be the same result for everyone but I thought some would be interested in the information.
