Trim Tabs

htillman · #1 10-18-2008, 12:58 AM

Getting ready to install a set of 12X12 Lenco tabs on a 23 Sceptre, where is the best place to install - between the outer hull edge and the first step or across the step? The tabs will fit within spec between the outer edge and the step but was curious if this was the best location.
Thanks for any info.

After looking at the hull and comparing to the drawings, there is only one way to properly mount and that is from the hull edge to the first step. Is this correct?

As far outward as possible.

Eddie, I like mounting them near the chine because it provides max rolling moment with minimum tab deflection. Min deflection = Min drag and fuel burn!

I control running angle mainly with engine trim and use the tabs for roll control, unless it's really rough and/or am heavily loaded and want to plane at 11-12 mph, where the tabs also help low speed low speed planing. Denny

This is where i mounted mine(12 x 12 Bennetts)on my 23 Tsunami,as recommended by Bennett Marine.
They are drop fin tabs,a closer picture of the drop fin is in the second picture.

John123, don't want to highjack a thread, but quick question on your picture concerning the kicker. How does the low mounting affect your boat with the kicker?

Gary,
I'm not sure what you mean by low mounting affecting the kicker.If you mean the kicker bracket itself,It's not that low.The anti cavitation plate of the kicker is just a bit below the hull.
The kicker has power trim,so it will be completely out of the water when under power with the main engine.
As for the tabs,the flat bottom part of the tab is flush with the hull,and only the drop edge is below.
I haven't tested it on the water yet,but i have a kicker setup like this on my current boat( 22'Trophy),and it works well.

Let me know if this answers your question.

I guess it must be the angle, the anti cavation plate looked like it was below the hull by several inches. Pictures can be decieving.

I know you are installing Lenco's,
but the same standard applies....
Mount as far outboard as possible.

See ya, Ken
