Improved Performance for Towing Skiers, Tubes, or Boards. Cut bow rise 50%, get faster and smoother acceleration, tow anything with ease, and run at top speeds without porpoising. Smart Tabs provide unparalleled performance, stability, and economy.

For Cruising or Fishing also enjoy better handling, and a smoother ride in rough water. With no electric or hydraulic connections Smart Tabs continuously adjust to the water conditions like shock absorbers. The stainless steel plates are held down by nitrogen gas actuators and automatically rotate up during acceleration. Easily installed on any wood, aluminum or fiber glass transom in less than an hour, with all mounting hardware and sealant materials provided. Includes two actuators sealed in EDPM rubber boots, two polished stainless steel plates, instructions and templates. Five-year metal and two-year actuator warranty.

SMART TABS are completely automatic requiring no operator adjustment while underway.

The nitrogen Gas Actuator provides LIFT at the stern of the boat by holding the trim plate down during acceleration. The amount of LIFT is determined by the actuator load rating and the trim plate adjustment, which is done at the time of installation.

SMART TABS start in a downward angel to maximize lift at slow speeds. As the boat accelerates, the water pushes up on the trim plates providing lift to the stern which minimizes bow rise, and allows the boat to plane quickly.

Once the water pressure exceeds the actuator load rating (maximum lift) the trim plates move up to a horizontal position eliminating any drag.

Even when cruising SMART TABS continue to work like shock absorbers. The constant adjustment to sea conditions allow SMART TABS to provide remarkable stability in turns, while crossing waves, while cruising, and while running at maximum speeds. No more sliding, porpoising, or chine walking.

The unique system is the only one of its kind in the industry. The internal valve system is truly "smart" in its design of controlling your boats performance.

  • It will reduce the minimum planing speed by 33%
  • Provide a level, more comfortable ride at lower speeds
  • Improve economy, handling and safety
As the boat speed increases, the water pressure also increases. Once the water pressure exceeds the Actuator load rating (maximum LIFT period) the trim plates begin to move upward until they are horizontal with the bottom of the boat. The internal valve system dampens the trim plate movement wich eliminates any instant reaction to minor water pressure variances. SMART TABS provide smooth and undetectable reaction to boat speed creating a level, more comfortable ride at lower speeds.

With an electric drill, two drill bits (1/8" and 3/16"), a phillips screwdriver, and two wrenches, just about anyone can install SMART TABS in less than an hour. Professional installers should be able to install SMART TABS in 30 minutes or less.

Easy Install - Work Great
by Daniel from Whitmore Lake, Michigan on May 20, 2016
Installation was relatively easy on my 1998 Sea Ray 185BR (even with having to mount the top bracket on the curved part of the transom. Took about 2 hours to assemble and install. Squirted a drop of clear silicon sealant (not supplied) into the holes before putting on the supplied sealing tape and screwing. The tabs work great, gets on plane much faster without bow rise, and stays on plane at lower speed, as advertised. Best benefit is that it doesn't porpoise any more. Money well spent.

Should come standard with a boat.
by Johnathan from Hubert, North Carolina on August 27, 2015
I never write reviews but I was so pleased with my trim tabs that I felt I needed to. I have an 18ft Marada with a 4.3L Mercruiser skiboat. Before the trim tabs with my family of six sitting in the back (small kids) I had to accelerate quickly to plane out. My wife hates to go fast ans going slow felt like the boat was going to capsize with the bow raise. The trim tabs made it so the boat can go any speed without excessive bow rise, it cut down on porposing, it leveled the boat and decreased the sway from side to side. Love them. ai also put them on myself with no prior experience and just followed the directions.

What a difference!!!
by Stephen from Owasso, Oklahoma on August 18, 2013
If you are having issues with bow rise and stability, than look no further. I have a Searay 185 that had a significant amount of bow rise when trying to get on plane. There was also an issue of the boat leaning way to far down when turning. The Smart Tabs have solved these issues and more. I can't believe the difference in the way my boat handles now. It is like a completely different boat. I'm not sure why boats don't ship from the factory with these installed. The only reason I am giving these a 4 star is because they didn't supply the correct hardware and I had to go to the local hardware store to buy 15 1/4-20 nylon lock nuts. Other than that these things are great.

Smart Tabs
by John from Brecksville, Ohio on April 25, 2013
If you are loosing speed at the top end then the boat attitude is too bow down at cruising speeds. Why? If you have moved down to 40Lb Actuators then the cause is other than the trim tabs. Are you trimming the motor out when on plane? Are you using a hydrofoil in addition to the trim tabs? Have you called us (800-233 0194)for further advice? 1/2 to 3/4 MPH could be as little as how much gas is in the tank during testing.

Benefits with a trade off.
by Jeffrey from Round Lake Beach, Illinois on April 25, 2011
The tabs did a great job to cure some of my boat issues. The boat is a 2010 18 ft bowrider 4.3 liter i/o alpha one drive. The good, this boat had bad bow wander at an idle, the tabs fixed this. The boat was lazy coming up on plane(yes it's propped right), the tabs also helped this. The bad part is I've lost about 1/2 to 3/4 of a MPH top speed. I have adjusted the pressure to the lightest setting and ordered a set of lighter struts (40 lb) still speed loss. I just can't see how dragging these tabs in the water could ever increase speed? My next try, just ordered a set of stainless turnbuckles to replace the struts. Going to set the tabs adjusted barely out of the water at 25 mph and above. Tabs should still cure the bow wander and add extra lift as the hull starts to drop below 25 mph.
