I haven't been around the site lately due to my 'puter being in the shop, and my house gutted to an empty shell at the moment. I have however managed to get some boating in! :D I hijacked my mom's computer to check in here and give and update one of my last threads: http://forums.iboats.com/showthread.php?t=197264

I finally got myself a set of SX tabs and installed them yesterday. I moved my tiedowns so the ropes sit just outboard of the outer chines and mounted the tabs so the outboard edge starts at the chine. Installation took about 1/2 hour and was easy. I only had 2 minor 'issues' with the tabs I recieved. First, the instructions on the packaging for the second row of pictures don't match the pictures above them. The instructions are in the right order, but the pictures aren't . Not a big deal, but I thought I'd mention it in case John D. isn't aware of it. The other issue is that one of the black nylon bolts in my kit that attach the tab to the hinge plate is about 1/2" shorter than the other three. This only leaves enough thread sticking out to get the nut about 1/2 way on. I'll call after the long weekend to see if I can get a replacement for it.

Now onto the good stuff! On the package it claims to reduce bow rise by 40%. After taking a test run yesterday, I can say that this is no exaturation, and maybe even an understatement! Before my bow rise was horrible and took forever to get on plane. I had to check the water ahead of me, make sure I was going straight, then gun it and hang on. The bow blocked all forward view and was rather disconcerting. Now my time to plane is cut by at least half, and I can see over the bow the entire time! They made a dramatic diffference!

The boat was also quite prone to porpoising in small chop, especially with a full tank of fuel which is under the floor directly in front of the engine. Now the bow stays down in small stuff, and settles down nicely after crossing another wake.

The third improvement is to planing at lower speeds. The boat would fall off plane at much less than 25mph. Now it will stay on down to about 16-18mph or so! This will be a great benefit for tubing with the kids! All this was with the 80# actuators set in the middle holes. Top end speed did drop about 3mph or so, so I am going to try moving them in one hole and see how it does. Even if there is no change is speed, the benefits the tabs provide are more than worth 3mph. I almost never run flat out anyway so for me I hardly notice.

All in all, I am thouroughly impressed with the performance of the Smart Tabs SX, and they are a great value for the verry reasonable price. I will gladly recomend them to anyone looking to increase their boat's performance and handling.

Kudos to Mr. D and Nauticus for an excellent product! :D

That sounds good, when you get them tuned to your boat that top end speed should come back and maybe even increase, you will also find you use less fuel.

Re: Smart Tabs a smart buy!

Has anyone used the new SX type?

The paddles are 9.5x10" and not the big 12x9" off the previoud metal version. However, they are $50 cheaper and advertise no maint.

Re: Smart Tabs a smart buy!

Yes, I have the 80# SX on my 21' i/o bowrider. Similar results to above. The bow rise is dimished so much that I'm thinking of moving the adjustment pin a notch as well. I keep my boat on a deep water lift so they aren't that easy to get to and I haven't tried that yet. Please let us know if you notice a differece NW Redneck.

I had 4 adults and 6 kids on the boat this weekend and it was just a joy to tube versus plowing and going off and on plane, and having to ask...ahem...larger guests to move to the bow, etc.

I echo the instruction part, they are so easy to install, but the instructions should be rewritten. For example I saw no mention that to mount the non-tab end of the acutator to the stern you simply let the tab flop down and it will be at the correct angle. I saw where before you had to use an angle template and now you don't, but not why or how you were supposed to get the angle now. Maybe they considered that to be obvious?...but nothing seems obvious when you are about to drill a hole in your boat!:D A phone call set me straight though.

Another install suggestion is to mark and drill one hole, coat your screw threads with some 3M 4200 or similar and go ahead and put in the screw. I marked all 6 holes, which was a little hard to do w/ the plate sliding around and then drilled...I got lucky the holes lined up well. It would have been safer to mount it w/ say one corner screw, then drill the subsequent holes thru the mounting bracket and inserting the screws as you went along. Brain cramp I guess.

Re: Smart Tabs a smart buy!

I observed that the 25 degree angle was also set by the tab hanging on the bracket after I got out my protractor and measured!!

Any way, I put a set of SX9510-60's on my 19' Rinker bowrider with 4.3L Volvo SX. Huge difference to say the least....

1. Up on plane much faster without the disconcerting "bow high" condition
2. Significantly reduced minimum planing speed (15 mph vs 22)
3. Significantly reduced wake
4. Reduced low speed wandering
5. Elimination of "run away" porpoising in choppy conditons/crossing other wakes
6. Ability to optimize drive trim setting (could only run full trim in before)

In calm water, I can't seem to trim the bow up since it seems like its plowing and I've also lost a few mph on the top end. I was on hole #3 (middle) and have moved it to #2 (less pressure) but haven't had a chance to run it yet. I'll let everyone know what happens.

Awesome product! They solved all of the issues I was having with the boat!

Re: Smart Tabs a smart buy!

I installed them on my CHAP 190 SSi- the 80# units-- I had to mount mine closer to center than I would have liked but the design of the transom required that--

great results with mine also except I lost top end even after moving to position 1-- Called Nauticus and they suggested the 60# units-- will try those next

It never fails! No matter how hard you try to make things correct from the start there is always something that needs to be corrected.

We appologize for the screw up in the instructions, and it appears that we need to sort all of the nylon bolts to see how many more are short.

Re: Smart Tabs a smart buy!

Well, I tried moving my actuators in one hole towards the transom, but I'm not sure if it is fair to compare the results yet as I had 2 more bodies on board. Ended up with the same wot speed. Now I'll have to take a while before I have a fair comparison, as during that trip I had a SOCT. (Submerged object contact prop) My spare is a different pitch (16 vs 18) and it may take a while to get another 18.

John: FWIW the performance of the product more than makes up for the packaging goofs. I know from reading your posts that you put your best efforts into your product and are genuinely concerned about your customers.

BTW, do you make props too? :D

Re: Smart Tabs a smart buy!

I've read so many good things about these I'm tempted. I have a Glastron 195SE 1998 with a 220hp Volvo v8. It handles pretty well already, gets on plane quick, doesn't porpoise. It definitely handles better at higher speeds. I boat on inland lakes only, and they get pretty crowded sometimes, it would be nice to be able to plane comfortably at lower speeds, just because it takes constant vigilance to dodge the tubes/skiers. It seems that the hp is at the top end of the rating for the 'biggest weight' SX tabs. Would I see a benefit?

Also, it seems that several people with boats in this size range are actually having better success with the next tab rating down from what's recommended, any thoughts?

Re: Smart Tabs a smart buy!

Here are some shots of the install I did a few months ago. Finally broke down and bought a digital camera!!

The tabs have done everything as advertised such as reducing porpoising, reducing planing speed, reducing time to plane, etc.

These are SX9510 tabs with 60 lb actuators. Right now, they are on hole #1 (closest to the transom). I have not tried this setting yet but I will be this weekend. On hole #2, I get reduced top end, higher WOT rpm (5,000 instead of recommended 4,600) and blow out in sharp corners. These are all classic symptoms of over-pressure at WOT.

If this setting does not work, I'll be replacing them with 40 lb actuators.

Re: Smart Tabs a smart buy!

Installed on my 14' 1958 Lonestar Monterey.

had problems with stability at WOT. Excellent cure. Once they were adjusted properly the boat seems to glide effortlessly. Turning is a breeze at top speed (35mph) with very little pitch to either side. Seems to stay perfectly straight.

Love those Smart Tabs. Will have them on every boat I own from now on.

Re: Smart Tabs a smart buy!

I can only say what everyone else has said. They do what they are supposed to do. I had to move mine up to hole two and it helped with the rooster tail. Did not get rid of it all the way so I have moved it up to the one hole and will see tomorrow. I wonder if my original set up was lower than it was supposed to be. I had read online that they were to be at a 25 degree angle and that the box had a template. My instructions that came with them did not mention the original angle and no template, but I set them at 25 degrees anyway. Online also said there was sealant for the screws included. Didn't get that either, but I had some so it wasn't a big deal.
