    Interested with anyone with experience with trim tabs on a 240 SD (2011 in my case). I see some 240 SD had them from the factory, more seem to not have them (mine do not currently). How beneficial on a 240 SD? And what size came from the factory / what size would be best for this boat? Just winter plotting at this point. Thanks.

    I have had a number of 260 SD... And the trim tabs in my opinion are a necessity.... it was always based on people on board making port or starboard heavier.. I always wanted to run level as they moved adjusting the trim tabs made the ride more comfortable for me.. It also helped running the most efficient with people in the bow. I don't think you would ever regret spending money on trim tabs.

    There is a Bennet trim tab forum... Tab man will tell you the Right setup for your boat...

    Seems many of the older models came from the factory with them.

    I have them on my 2007 240 Sundeck. I haven't used them yet, there was a leak early last season and I went the whole year without using them. I can see the benefit, as there were many times that I ran with a list to one side or another depending on where people sat. I replaced the seals and flushed the fluid this off season. Looking forward to seeing how well they work.

    Another benefit would be taking off in shallow water, dropping the tabs should lift the stern quicker and help get up on plane.

    Just an FYI... if you compare to the 2009 and earlier 240SD, that is a bigger boat.

    You can NEVER go wrong with trim tabs. They can only help and it will be pretty much a night-n-day difference in terms of hole shot, leveling, controlling of porpoising, etc. I even added them to my 215EC, which is of course smaller than your boat. In my opinion, once you own a boat with tabs you'll never want one without them. Somewhere around 11" or 12" rings a bell. Can't hurt to go a bit bigger (span), either.

    Trim tabs came standard from the factory on my 240SD. I didn't need them for hole shots but did use them occasionally to level the boat while underway.

    I added the Lenco trim tabs to my 1996 230 Overnighter last year and they made a world of difference as she always seemed to ride slightly leaning to Starboard even if I sat in the port seat. Best add on I've done so far to the 230.

    Agree, they are good to have on a boat this size, whether correcting due to wind, current or load onboard.
