For little investment, you might also try one of the following first. I
have no experience on larger boats, however I know they work well on smaller
run abouts in the 16 to 18 ft. range. There are several other manufactures
on the market besides this one.

Yes, sometimes known as a Doel-Fin or similar. They are a lot less
expensive than trim tabs and very easy to install. That's what I'd
try first. Also, make sure you are trimmed all the way down when
starting up.
