Re: boating question please thank you
Only my opinion?-- The engine fins help to get you up on plane faster with "less drag" than trim tabs, at slower speeds. Ounce on plane the trim tabs come into play to stablize boat. "I say leave them on.

" Just read link! the skipping they were talking about "in choppy water turns" are directly related to trim tabs! If in a turn and the trim tab loses contact with water you tend to skip away from direction of turn. The engine fins "always" have contact with water and therefore,guides the boat into a smoother turn and helps keep the trim tab in contact with the water. My .02
