More work to install, negligible benefits compared to hydrofil by Keith - Port Alberni, British ColumbiaJuly 28, 2013
I have a small 13' aluminum hull shallow-vee RIB with a 35hp 3-cylinder Evinrude that I wanted to see if I could reduce the porpoising and wave handling. I purchased the smallest one using the selector tool as I have relatively small motor and very light boat. As I didn't want any stainless hardware reacting with the aluminum hull below the water line I mounted these to large aluminum plates (very stiff) and installed the retracting kit as well. I removed the Attwood Hydro-Stabilizer (bolt on hydrofoil to the anti-ventilation plate) and fixed up the empty bolt holes as directed. After installing (which took awhile as I wanted everything to be square/sealed/etc) I went through testing the five different settings on the Smart Tabs with each of the five different trim settings I have on the engine. Unfortunately with no setting was I able to reduce the porpoising over the hydrofoil alone, and even with the plates on minimum (or retracted) and the engine fully tucked in, I always have significant ventilation issues in corners without the hydrofoil. For getting to fishing holes it's not so important but cruising or water sports I can see it being quite significant. My time to plane is slightly higher, but I can hold plane at about 13mph vs 15mph. Efficiency isn't noticeable over 2 tanks (100L) but my top speed seems to be slightly less (1-2mph). They are always in contact with the water so I would imagine they have more drag at high speed than a hydrofoil that lifts out and runs dry at high speed. It seems like more work with both installing (which required me to move my transducer, speed and temperature sensor) and limits my mounting for an electric trolling motor. Also, I should be retracting them with putting it on the trailer and it's more likely to wear down if the seals go. I do see issues with the hydrofoil as well (damage to the anti-ventilation plate, holes in the engine to mount, force on the motor/transom which I personally think is negligible compared to the weight of the motor) but overall so far they seem better. I will try a larger anti-ventilation plate later. I could see them being beneficial on stern-heavy deep-vee boats that squat and have issues getting on plane, but for the small light boat I have, I don't think they're the best solution.

Another Succes Story by Jim - Linn, MissouriJune 24, 2011
G-3 1652SC Jon Boat, 50HP 2 Cycle Yamaha Outboard with Power Trim I don’t ever see reviews of the Smart Tab SX’s on an aluminum jon boat so here goes. My son and I just purchased this boat and it was so bad at porpoising and bouncing that you could barely ride in it unless you only traveled at half throttle. It didn’t seem to matter how the motor was trimmed as it only changed the problem instead of fixing it. An email to G3 and they only referred me to my local dealer. Both friends and the local boat dealer suggested either a whale tail on the motor or installing wedges under the motor mount to get more trim. Neither of these options appealed to me and then I read about these Smart Tab SX’s. Installation only took about a half hour and off to the river we went to try them out. Right off the trailer and a little throttle for the turn around to go and pick up my son I immediately noticed a big difference. The boat leveled off almost right away without even letting off the throttle. I picked up my son (I am well over 300 lbs. and my son is tipping the scale a little over 200 lbs.) and we both sat in the rear seat. We took off at full throttle and the boat immediately leveled off with no porpoising or bouncing, just a little chatter when we hit waves from other boats. I now turned over the helm to my son and he put the boat through its paces. I sat on the bow and it didn’t seem to make much difference as the boat leveled off only slightly faster. Back to the rear seat (more comfortable) and my son pushed the throttle forward and done a series of U-turns. Before the Smart Tab’s the propeller would come out of the water, now it continuously makes contact with little or no loss of power. I also checked the speed using a GPS and maybe one MPH increase in speed but I really wasn’t expecting any significant increase on a boat and motor this size. All I have to say is WOW. What a difference Smart Tab SX’s have made. They accomplished everything I was hoping for and more. I would suggest to everyone to install these on your boat and find out what you’ve been missing. (I am also going to suggest to my local dealer to start selling these and forget the whale tails)

They work! by Paul - Plaquemine, LouisianaMay 18, 2011
I will never own another boat without these installed before I pick it up. Installation was easy, but I was nervous about drilling holes below the water line. They sealed well and don't leak at all. The boat almost jumps out of the water on plane now and it improved the steering tremendously. It took a little getting used to but now I love it. Buy these. You won't be sorry.

SX Smart Tabs by Thomas - Edgewater, FloridaSeptember 17, 2011
Best money I have spent on this boat. It's a 17' Sailfish (polar type, square front) with an 8' beam, 60hp Evinrude. With the Smart Tabs, this baby jumps out of the water, and is great on top end. I think I can almost walk as fast as this boat will stay on plane in slow speed. Great product, highly recommended!

Incredible! by Lance - Newaygo, MichiganApril 23, 2012
I have a 16' Alumaweld Express 16' aluminum style bass boat. I converted my outboard to a jet drive to steelhead fish on our local river. After that, I could not get up on step fast enough to even take it near the river. My local jet boat guy gave me several options including float pods, a bigger 2 stroke instead of the 4 stroke I have (added low end torque) and so on, but the cheapest option was at least $1300. After the trim tabs, everything has improved dramatically. The boat gets up on step in a hurry, the tracking is awesome, no porpoising or chiming ever. When I was researching these another user made the comment that all boats should come with these, I have to agree to an extent. I put myself in a pickle and Nauticus got me out for a low price in comparison to my other options. Thank you!

Great addition by Alkesh - Columbia, South CarolinaJuly 09, 2013
The tabs installed in about 25 minutes for me. Put up some masking tape, drilled holes, put in the silicone and screwed everything in. Couldn't have been any simpler. I put them on my Byliner 175 which does not have a flat transom. But a quick call to Nauticus and they shipped me some special brackets to use instead of the included ones, free of charge. Great service! Lastly, it rides much smoother and gets out of the hole must faster as well. Worth the money.

I'm stoked!!! by Carlos - Deltona, FloridaApril 17, 2010
These tabs work unbelievably. I installed them on a Chaparral 185 SST and now the boat rides like a 24 footer! It glides over 2'-4' chop at 48 M.P.H. without chime walking or bouncing! Crossing boat wake is no longer an issue, it will plane out at 15-18 M.P.H. at quarter throttle and I picked up a couple M.P.H.. What's not to love? Kudos to Nauticus for a great product!

Best Bang for Your Boating Buck by a CustomerOctober 27, 2010
I have a very stern-heavy boat -- Starcraft 15-foot Deck Boat -- with 400-lb motor, 200-lb operator, battery and gas all at or near the stern. Before installing these tabs, getting up on a plane was a laborious process requiring lots of power. Now it's a breeze. Time to plane is faster rpm to plane is lower rpm to maintain plane is lower. The ride is enormously improved -- chop is smoothed out and porpoising eliminated. Nauticus claims 15% faster acceleration, 50% less bow lift, 10% more speed and 11% better fuel economy. Except for fuel economy, which I didn't measure, all these claims were accurate. Installation instructions are clear and simple. I can't recommend these tabs too strongly. They are the biggest bang for my boating buck that I have spent in a long time.

Works GREAT! by James - Macclenny, FloridaMay 11, 2012
I own a 19 ft Glastron GT185 with the 3.0L engine. The smart tabs make my boat get on a plane super fast and stay on a plane while going super slow. My boat will even get on a plane with 3 kids in the back and none on the bow!!! What is even better, the front of the boat barely comes up when you go full throttle!!! I love these things!! They were also very easy to install.

Game changer by Joseph - Naples, New YorkAugust 06, 2013
I installed these on my 1990 Galaxy 19 ft cuddy. The boat has a small (2.3 L) Volvo Penta that could barely get on plane and could not plane below about 20 mph (this made it tough to pull little ones on a tube without traumatizing them). Since installing the Smart Tabs, the boat now planes far more easily. Bow lift is greatly reduced and the boat can plane easily at 15 mph (I've pulled a tube at speeds as low as 12 mph). The boat also handles choppy water much better with considerably less porpoising. There does not appear to be a noticeable change in top speed one way or the other. Installation was pretty easy. I had to remove a nonfunctional transducer to make space for the tabs, which was no big deal. I've tried different props, engine tunings, steering and engine trim settings and nothing has improved the performance of the boat nearly as much as these Smart Tabs. Highly recommended.

Manufacturer's Response: by a CustomerApril 08, 2011

During the manufacturing process we found that there were design issues with the SX9510 series of Smart Tabs in early production. This was primarily noticed on boats with deep V type hulls, V8 power, and boats capable of speeds in excess of 55 mph. In all cases we provided replacements (of new design) to the consumer at no charge.

The specific change since the introduction are the Tab plate hinge bosses, tab plate ribs, Hinge plate bosses, and replacement of the Spread and Lock hinge pins with nylon bolts and lock nuts. Since these changes have been made, the rate of warrantee claims has been reduced to less than 2% which includes product returns of all types. In some cases the returned product was never used.

In summery, we are confident that all of the issues with the SX series have been resolved. We are always looking to improve product quality and consumer satisfaction. We guarantee our products 100% or your money back

Best Regards,

John E. DeAgro

NO more low speed wander! by Curtis - Oconomowoc, WisconsinJune 25, 2012
I know v-hulled boats are famous for low speed wander. I hate that. The smart tabs got rid of it completely on my 20' Sea Ray Seville! I know that's not their main purpose, but it is my favorite feature! They also have done exactly what they are supposed to do. Less bow rise when taking off, plane out at a lower speed and quicker from a start. Fantastic product, and really easy to install.

Works fantastic on my Chaparral by a Customer - Ridgewood, New JerseyApril 21, 2011
I have a 2005 21' Chaparral and wanted to get a little more performance out of the boat on the hole shot. I did some research and found some amazing claims on the iboats' forums. I took the plunge and ordered these Smart Tab. The really do work as advertised and I could not be more pleased. Install was pretty simple and they look OEM. I would recommend to my friends. Wayne

Review for "Factory Blemish" SX Smart Tabs For Boat Length 18' - 22' FT and 150-240 HP - by a CustomerMarch 31, 2009
All looks in excellent condition. I read something about removing half the pressure in the two shock absorbers for a better operation. I wouldn't do that unless it was in the instructions however there is nothing stated about doing anything to make them work properly. So are the two shock absorbers suppose to compress by hand? They don't seem to move at all. Thanks, Bob.

Not universal, no response to emails by Faizal - Calgary, AlbertaJune 05, 2012
The transom on my boat is set at an angle, so the actuators are not long enough to reach the transom, although there is not mention of this on the website. The nauticus website says you can convert smart tabs into pro-trollers with the extra attachment, but it does not work with these. These tabs have a stop of 25 degrees, which prevents them from shifing into the trolling position. This was the main reason I bought the tabs. Another $50 down the drain. Nauticus did not respond to several of my emails which made a bad situation worse. Installation will cost me AT LEAST 3-4 times the cost of the smart tabs because of the transom angle. Buyer beware!
