Hi Gang,
I am new to this forum and need some help. I just bought a 272 Baha Cruiser Fisherman. It has a 350 Mag MPI motor.The boat started great and sounded good. The problem came when I tried to get the boat up un plain. I tried everything I could think of but it wouldn't plain out. 3000 rpms 12 mph. 4200 rpms 16.2 mph. 4200 rpms was the most rpms I could get.
