My 27 Activator Has 280 trim tabs on it but noticed most 27s are using 380s. Would like to know the pro's and con's of of the 380s. I know that I can just replace the bottoms which I will do if it has a positive performance to it. I know at top end you run with tabs up but but if there is a positive anywhere in in rpm range I will replace them. Best boat I've owned so far.

Totally different boat, but on my 37AT I direct swapped the bottom plates from 280 to 380, and I definitely liked the boat's handling better. I left them at neutral nearly always, except getting on plane.

I have 380s on a 27. Will be out soon to try them. I've also had 280s on a 27. I'll bet you could get into trouble fast with 380s. Even with 280s. I mostly ran them flat to slightly negative or raised

Mine is a stepped hull and the tabs are about an inch above the bottom on transom I run them full up when running hard and only use them when just on plane. they are too touchy and will lean the boat very quick. I thought that the 380s would do better because they look narrower at the tips. I'm going to also try motor oil in the pumps rather than ATF that's in them and see if it slows their reaction time on them.
