Hey guy''s i also did the same changes two new water pickups , extra water port,extra turn fin,the prop and motor are stock.The boat always ran great with the batt pos. for cog.But now at top end it rocks from side to side at a fast rate. you have to get off the throttle some times to settle it down.the new turn fin is set to match the old one.
Anyone got any ideas?????????
your CG could be a little loose
try moving your batteries about 1/2" forward and see if that helps
