Trim Tabs Revisited
|Author||Topic: Trim Tabs Revisited|
posted 06-15-2001 09:55 AM ET (US)
I am putting trim tabs on a 20' Outrage with a single 150HP Johnson and seem to have settled on the 12" x 12" size as the largest that is practicable. Question: Do I mount the tabs on the reinforced center portion of the transom or on the outer portion of the transom between the reinforcement bulge and the chine?

You want to get in touch with "the Kingfish"!
Go back and reveiw some of the lengthy threads on this subject.

Thanks for your input. I have reviewed the
previous threads carefully; that is why I posted my inquiry as "revisited." From what has been said before I am assuming that Kingfisher and CPD boats mount the trim tabs outboard of the reinforced center area. I have also seen the tabs mounted directly on the reinforcement so I am looking for more information from our resource bank as to the best place for my tabs.

The tabs on my 22 Revenge are mounted inboard on the reinforced part of the transom. It came that way from the former owner.

Most tab manufacturers and boat manufacturers will tell you and an understanding of hydrodynamics will support them, that in order to achieve maximum benefit, mount the tabs as far outboard as possible, short of the chines if your boat has them. Mounting them inboard to take advantage of the reinforced area of a Whaler's transom is like mounting training wheels on your child's bicycle right tight to the rear wheel because you couldn't lay your hands on the right wrench just then.

I agree that generally speaking tabs are probably most effective mounted as far outboard as possible. However, the tabs mounted on the reinforced part, as mine are, work just fine.
