I have used Bennetts (made in Florida) on my 23 Webbcraft big block for 13 years and have had good luck under normal boating conditions in the mid 60 mph range. You can get them black powder coated with single or dual rams. West Marine,
etc. sells them
The cost won't tear your head off; around $500-600 for the set complete.....easy install.
Would love to have the high end tabs, but $2K is
a lot for inland boating.
Trim-master in St. Louis also makes a good tab for smaller boats.
Good Luck,
