I know that there is at least one person on this board who has installed a rigid trim tab (like those on a drag boat) but Iíve searched for a while and havenít had any success finding it. I plan to remove my nylon hook that I have glued to my stern and replace it with a trim tab but I donít need to adjust it for any reason once I have it set to correct the porpoising problem at slalom/barefoot speeds. My Maristar wake is fine for our needs, the only thing I need to correct is the porpoising. My plan is to by a Bennettís or Lenco trim tab without an actuator and use SS adjustors.
A smaller version of this:

My Maristar 200VRS rides with the bow very high. It appears to be the hull design around 95 with the euro platform, some other 200VRS owners have the same problem. Over 35MPH it rides like a bass boat going down the lake, just the stern touching the water. The porpoising gets worse the more people I have in the boat, worse in the bow. No problems with just 2 people in the boat. No difference using a 3 blade or 4 blade prop.

I glued a 3/16 inch wedge on the bottom of the stern and it rides more like a direct drive.

My father-in-laws '89 Supra Comp has exactly what you're talking about installed from the factory.

Here are some pictures of a barefoot plate/trim tab that was installed on KSO's 2003 197 TT.

Here is a link also to the barefoot boat review that barefootcentral did back in 2003. This is where I goat the pictures.

I saw one on a Supra or Malibu a few years ago.

Thanks for the pictures. That is EXACTLY what I want to do. Just have to find the hardware.
