Have a buddy who just bought a 35 fountain ( non step hull). Has twin 454s that are stock except headers with 1.5 bravo outdrives. What pitch prop should he be running? I think before it was sold someone switched the props because they are 19 pitch and I though 24 or 25 but I don’t want to give wrong info and waste his money. Thanks in advance!
