On the large step 32's it seems above level doesn't give anymore speed but does make it rock more. Mine doesn't have the limiters and I have tried running with them above lever and the speed didn't change a bit.

Reggie said way back when to always run the tabs parallel with the boat's running surface.

I think that depends on the boat though now. That may have been true on straight bottom boats.
However, step bottom boats have a "disjointed running surface" as the actual "surface" is a straight line drawn across the aft points of each step.
Remember, steps were invented to create a natural "rake" in the water. Introducing air under the hull was a by-product.

With that being said, I do think it varies on the boat.
On my trim indicators, I have "neutral" or parallel with the aft running surface of the boat (behind the (last) step) MARKED with a Sharpie line. That's normally where my tabs stay parked.

When you need to adjust trim for running conditions, remember you can run the drives at different trim levels as well. That may adjust the angle of the dangle side to side in quartering seas or with a breeze; without scrubbing speed as tabs can do.

THE MOST important thing when it comes to adjusting tabs for changing the attitude of the boat side to side is DIFFERENCE between the two tabs. For THAT reason, I don't know that I would chose to run upward limiting blocks.

But, every captain has their own method of running their own boat.

Sunsation installed them on the old Dominators. Not sure if they still use them on the newer twin-step S,SS,SSR,XRT hull. You could post something on the Sunny forum and see if Jeff Sunsation responds..

Did you find out if it's a Merc or Fountain part?

It is a Fountain Part #2542 according to David Hardison....$65/each!

I've got them on my 2002 35' Lightning, assuming from the factory.

Eddie and I spoke about removing them to loosen the boat up a bit to gain some speed. ...but then he talked me in to putting in a new roller cam....


I gained some speed!

Anyone have a pic of what they look like?

Mr Maine

If the boat runs best with tabs parallel with the bottom, why not just run it like that? Why do you need stops for, assuming you have mechanical indicators? I'm only curious...

That is what I do, even with the bottom is 3 on my indicators for both drive and tabs.
