I approached the subject of a setback bracket with the motor installer and he told me that I might have some trim problems if I did. He said trim tabs might be necessary. Larry, you're the guru on this. Do you see any problems? Another member on this site is repowering his Revenge as well, with a single Merc. Is there a difference between the twin installation and the single as far as brackets/tabs go?

Todd - Boat is sounding nice. Regarding the need for "stern lifters" (aka trim tabs) on your Revenge, I doubt it. I don't need them on my 18 Outrage, which is quite bow light.
To the contrary, I even run Mercury Laser II bow lifting props! With a bow heavy Revenge, I would not think they're necessary. Try them without first, as properly putting these on a 22 is a big job, as the Kingfish will testify.

But there are those that feel they need them. Backlash is running his 200 Yamaha on a setback bracket, and has them. But his boat is a newer 21 Walkaround. And as mentioned, Kingfish also likes them on his 22 Outrage.

I don't even use them on my 25, where the bracket setback is 26".

If I am corrent, the main reason for using stern lifters if for slow speed progress into
a sharp head sea. The engines will certainly have enough tuck-in to prevent porpoising at any speed.

Caddis- I run a 22' OR and put the new Bennett Sport Tabs on about 6 months ago. Obviously the boat comes out of the hole much quicker with the tabs than before the tabs. Also, with tabs down the boat handles big chop etc much better. I know what's new.

What has surprised me is how often I use one tab or the other in a stiff cross wind. The combination of stiff wind and wave hitting at about 45-90 degrees
causes the boat to list away from the direction of the wind. Adjusting the far tab down corrects quite nicely and evens the boat out. Pretty neat.

Saturday I got caught in 20 mph winds right in the kisser. White caps, the whole 9 yards. Put the tabs down and throttle up. Smoothed the ride home. Prefer hitting the waves as opposed to them pounding me.

After 6 months with tabs I wouldn't go without. .03 David

Thanks for the advice. I will give it a shot without, and if necessary will add later. Now if my motors would just come in...
