I recently sold a 502-650 to a customer of mine that owns a Cougar MTR25. It uses a Bravo drive, 1.5 ratio and for the first trial he turned a Merc 4 blades 24 pitch at 5900rpm (best hp) and he barely reached 81-82 mph. To me the boat should perform better. Does anyone own the same tunnel boat (it was build in 1990) and what speed does it reach. Any suggestion about prop?
Thank's.
