trim tab placement

[bigeasy1]

Different tab types,require different mounting and placement methods.
I just finished installing a set of Bennett 12"x12" drop fin tabs.I actually spoke to the folks at Bennett while i installed them.
My tabs required they be mounted with the leading edge flush with the hull bottom,and the trailing(outer) edge,at a negative 5/8".
Other Bennett tabs,like the sport tabs, call for the leading edge to be 1/4"above the hull bottom.
They are pretty easy to install,if you take your time and follow the directions.
They recommend mounting all their tabs as far outboard as possible(about 3"in from the chine).

Here's a couple pictures, of the tabs on my transom in progress.

For information only...Why did you install that type of trim tab? I will put tabs on the 21 and I am just gathering facts. Transom looks good.

I put those on my last boat (22' Whaler). They have more surface area with the "fin" and were perfect!! Tom at Bennett offers the definition of service! He's a BIG help.

Island,these 12x12 drop fin tabs were the size recommended to me by Tom at Bennett Marine.
The 3" drop keeps more water under the tab,increasing lift.I think Ken(fellowship) can explain it to you much better than I.

I'm only running a 250hp 350 I/O,and will have a Yamaha kicker on the back,along with four downriggers,with 12lb weights,so with the extra weight i figure the more lift the better.

Hopefully,i can splash this thing by the end of summer.Engine is in,new transoms in,decks done,major glass work is done,now have to glass the rear cap back on,do the wiring, install the arch and rocket launchers,electronics, paint etc. etc.

As for Bennett Marine,i can't say enough about how good their customer service is.They are great.I think i may have talked to ken,about a week ago,explaining that the pump cover was cracked,and that i also needed a new hydraulic fitting.
A few days later,they arrived at my house at no charge.Thanks Ken.
