I also have a closed deck Pulsare 2400 with a Bravo FS 24P. What does the Bravo 1 do, chine walk? Does the ProMax 24.5 completely eliminate the chine walk or what type of stability you had? Is the 24.5 ProMax a labbed prop? Did you run both at the same engine height?

the bravo 1 chin walk and porpoise a lot same height. pro max it`s not labbed . promax is better but not perfect i ride faster with promax .

Merci bien, mon ami. How much faster is the Promax? Do you have a 300XS or 300R engine? I have a 300R closed deck with a Bravo FS 24P and some chine walking between 70 - 72 mph. My friend has a BRX with a 300R and violent chine walking at 70 mph.

Bonjour encore mon ami, Your jack plate in the picture looks like at least 8" of set back and maybe 10". You can check with some members on the Checkmate forum but porpoising and other handling issues were sometimes caused by too much set back with the 400R which weighs at least 150 lb more than the 300XS or 300R. The 400R has 4"-5" of set back built into the bracket. The blue 400R / BRX that I test drove did not porpoise (but it had trim tabs) and almost no chine walking at 76 - 77 mph. I think the Atlas bracket was about 5" of setback (plus another 4" - 5" built into the motor. However there are some members with 8" of set back on their Atlas jack plates.
