I have a 2002 353 Fastech and have had it since end of summer 07. It runs great in relatively smooth water but when it gets choppy it always seems to list portside. I noticed this the first year but attributed it to needing to learn how to handle the boat. That wasn't the problem cause it still does it now. I can compensate with the trim tabs but I can't figure out why its doing this. The drive and tab guages are accurate and the rpms are the same at the throttle. I don't have any other handling issues with it. Does anyone have an idea what is going on. The boat has only 170 hours, twin 500hp's and was surveyed and dealer inspected before I bought it so I don't think it had something was amiss when I bought it.
