Hello, I have a southern skimmer 1660 with front/rear decks and center console. Im currently running a suzuki df50 with a 11.5 x 13 prop. The boat is a little slow out the hole unless the passenger stands towards the front. Top end seems fine but the motor likes to rev over recommended rpm (recommended 6500, motor can do over 7). Im not a real big fan on speed, but curious of some recommendations? I've had the top speed on gps around 27-28 @ 6500 rpm.
