I have had a 17 SR with 9x12 Lenco,s and a 17 SC with 9x9,s.  The 9x9,s were a little bit of a dissapointment . I always wished I had gone with the 9x12,s. The 9x9,s  just didn,t quite have the range of adjustment the 9x12,s had and left me wishing for a little more.  Just my experience. - John

 :yeahthat:  When I did research on trim tabs I had read both opinions - that the 9x9's worked and were sufficient and I read the 9x9's were insufficient and it was recommended not to use them:shrug9:

I would not take the chance on 9x9's myself only to change later......go with adjustable.  Although saying this - I do take 3weights opinions  in gold.

Most, or all of the (not very many) reviews of the 9x9’s are on 17 ft boats. Mine is a 16, although probably not much of a difference. I agree with 3WT that non-adjustable smart tabs would probably work very well on my boat. I just would really like the adjustable. 9x9 may be my only option that would fit, and still give me some transducer options. If I did go with a 9x12, I would most likely have to shim the outer part of the brackets

I thought I’d ask if any of you that have, or have had tabs on the smaller Arimas is there any problems with cavitation, over heating, or any other motor problems related to the disturbance of water from the tabs being so close to the motor? I read somewhere that the tabs should be at least 10 inches away from the prop rotation area.

Here’s some pics of what I’m talking about. Because of the curve on the transom the straight edge, or tab bracket will not lay flat unless moved way over to the left. Look at the ruler at the “10 in area”, there is about 1/8 or 1/16 inch gap. My transom has a very gradual curve to it



Fisher, that is a huge radius! Wondering when Defiance changed the mold? Anyone else with a new Arima have this same change on the transom to sponson radius? It seems a little strange as many owners that want to add tabs to their boats that they would redesign this area and reduce the available space that is already tight??

Speaking of which, just a couple of comments on tabs on Arima's. This is a much discussed topic but always good to review for new or would be owners, Like Buddy who is in the process of setting up a brand new 17' Chaser. Most agree that tabs are one of the most important improvements to their Arima. Some have mentioned already in this tread one of the benefits is the side to side trim. This is so important with the addition of kicker motors and accessories that change the balance of the boat, not to mention the live loads we add that are changing all the time, like people! But there are other important reasons for tabs on these boats.

One member named his Arima the "Fat Bottom Girl". The design of our boat makes them very stern heavy. Gas tank, 4 stroke motors, batteries, heavy transom, etc. make them sit low in the water. Trim tabs greatly assist in getting up on plane. You might not think this a big deal, but when you have extra weight in the boat, (which we all eventually do), it is so wonderful to tab down to get her up on plane versus moving weight forward! Also, the ability to "lift" the stern allows the boat to plane at lower speeds. Which comes into play in the next big benefit.

Our boats are such a stable fishing platform (which we love) because they have a wide flat bottom. There is a decent bow angle but if it doesn't come down in contact with the chop, that force hits that flat bottom and transmits immediately to your back (which we don't like so much.)  :hoboy: I had a whale tail on my 90 Honda when I first bought it which never was able to lower the bow enough to cut the chop. Man, when I installed the Lencos, what a difference. Now, I'm not talking about 3' and greater "seas" but 1-2' chop and even moving slowly through a little larger stuff they help a bunch.

Finally just a word of experience to those that are setting up new boats. When I first got mine, Instruments were on the top of my to do list. And I couldn't wait to slap a transducer on the stern and immediately start filling my boat with all manner of aquatic life! Within a year I got to Trim Tabs on the list, and of course had to MOVE transducers. So, before drilling that mount for the transducer, assume that you will be installing tabs (because you will) and plan, plan, plan. In fact, thinking about Fisher's current process, if I had that much radius on my sponson/transom and limited room for a transducer I might seriously be thinking about a through hull ducer or perhaps mounting on the sponson.

Anyway, food for thought. No matter what you do, at least fiberglass is pretty easy to fill and repair! Good luck!

Thx John, curious does your transom have the same radius or curve as mine does in the pics I posted?

Dbhazjack, thank you for the detailed post, you nailed it! My reasons for wanting tabs are pretty much everything you said. Believe me, I’ve read ALL the tab threads. Some may think talking about tabs again is very redundant, but as you stated for us new Arima owners it’s VERY helpful to us. It’s not easy to drill 18-20 holes in a brand new boat transom without being absolutely informed on what your trying to accomplish. I like to measure 10 times, and cut once. Incase you guys haven’t noticed, I’m VERY picky about my boat. As you can see in the pictures, and as you said I did plan ahead for tabs when I mounted my transducer. A 12inch wide tab would probably fit, but I would be giving up my whole transom to do it with that radius I have. I spoke to Jim at Lenco marine and he assured me that 9x9 would work fine on my size boat. 9x9 may be the better option in my case. He also said he had a customer with a 20 ft Proline boat (those boats are heavy) that had limited transom space put 9x9’s on his boat and was very satisfied with the performance of them. Thank you guys very much for your help :yeahthat:

John, did you have any problems with the right side of the brackets laying completely flat against the transom with that curve? Thx

Nope, there was enough flat area before the curve. If you are worried, just go for the 9 x 9. I'm sure they will work fine.

Hmmmm, I hate these decisions! Maybe I can purchase both the 9x9 and the 9x12 to actually see in hand what I’m working with. Just have to order from Amazon or similar that has a good refund policy

Great idea! I’m pretty sure that the 12” tabs would fit and suck up tight looking at Chaser’s boat but why not order both and return what you don’t use? Being careful, taking your time, asking questions, and being sure before drilling and cutting IS the smart path Fisher! As everyone that has taken the wrong path has discovered! Which doesn’t included anyone on this forum  :beerchug:

There is a specific size drill bit for a specific screw in fiberglass. If the hole is too small, the screws will break off.

With all this talk about tabs I just measured mine.8 inches wide and 9 deep.Not sure of the brand.They bury the nose of my 19 in the chop.They came on the boat when I bought it new.The 9x9 should work great on a 16.

I have the M-80 as well they claim I think 30% more efficient due to the batwing design. They work great on a 19. Only one I considered for the small size.

Ok, got both the 9x9, and the 9Lx12W Lencos. Looks like either will fit. I will probably do the install next weekend. So, let the voting begin, should I use the 9x9 or the 9Lx12W on my 16 SC?
