Just don't mount them as per the Bennet instructions, they mount them flush with the hull bottom that can scrub speed. There are several good posts on mounting them for best performance.

CB,

I think that the M80s would be a great choice for your Sweet16, but of course I am a little biased.

As far as mounting them so that they clear the waterflow and don't scrub off any speed when reacted, the M80s mount 1/4" above the hull bottom at the transom and 5/8" above the bottom at the trailing edge.

This allows the Trim Tab to ride above the water when fully retracted and should bot take anything off your top end.

Thx Tom. With all the rain in PA I'll probably install my ST9's this week and this info will help.
