I have 3 batteries 20 plus gallons gas empty live wells , 200 merc efi , 23" pitch prop. The boat runs 60 mph with this prop and 65 with a 25 ", but it has trouble pulling pulling my 200# son up on a salome ski. We added a SE sport 200 cavitation plate extender and it might have helped a little. It did help the low speed performance. ( stays upon plane better ) WE were thinking about trim tabs or maybe a jack plate with set back With 2 or 3 people on board this boat jumps on plane in seconds Anyone have any ideas ??
