Boat tilting to starboard only on plane

[Rncab218]

2001 Sundancer 310 I/O Bravo 3s
Had the boat 4 years and last 2 times out boat tilts to starboard when on plane like never before. Can correct with trim tabs but this is new. Had south wind first time and thought that might be the cause but not a strong wind second time. Any thoughts or ideas before I have mechanic pull the boat? Thanks!

Maybe one trim tab is stuck fully down?

Not saying it can't be mechanical but I have experienced the same with wind, port & starboard on my '97 330 DA with 454's & V- Drives.

no list in the slip? how about steering, do you feel a pull or do you have to correct? If it's not weight related I'd say check tabs, one drive not trimming at the same rate as the other, or steering pins causing slop (if the steering seems off)

Or you may have lost a tab like I did last year.

In addition to checking your tabs, check your outdrives to be sure they're trimming equally. It's also possible the trim sender for one of the drives needs to be adjusted to show correctly on your gauge.
