Saturday I saw something surprising- I think. Maybe it was bigfoot?? I stopped by a marina new to me and there was a Whaler, approx 27' with a huge cabin in a slip. I am not familiar with this model but looked out of the 80's. Nice boat. It had a Whaler drive on it. I'm certain about that. But low and behold a trim tab cylinder was attached the the Whaler bracket's behind. Since the boat was in the water, it was not possible to see the tabs or just what these two trim tab cylinders might be attached to. Has anyone else seen such a set up mating tabs (Bennett cylinders) and Whaler Drive. Otherwise the boat was rigged for offshore fishing-out+down riggers etc. Thoughts. Thanks David

Just about 100% of the 27's whether Whaler Drive or just transom style had Bennett trim tabs.

The Whaler Drive had a recess about 4" to 5" molded in the bottom where the trim tab hinge and a portion of the tab was housed so when retracted would be flush. Early models prior to Whaler Drives had the tabs mounted to the transom in the normal fashion.

This tab system was termed by Whaler their "planing system".

I am assuming you could saw the actuators mounted to the transom. If not then the system might not be Bennett but a custom one after market installed.

David,

Over the years we have made many custom designs for Boston Whaler. The Hydraulic components are pretty much standard, but we fabricate stainless steel Trim Tabs to Whaler's specifications to fit into deferent pockets and recesses that they design into the boat.

If you look at boats with recessed Trim Tabs you will find a wide variety of shapes and configurations that are not our standard of the shelf systems. Our factory makes all of our components, including the Stainless Steel fabrication, so we can make just about anything a boat builder might want.

We continue to make many different configurations for Boston Whaler.

Hope this sheds some light.

Best Regards,
Tom
Bennett Marine

I hope all my classes are as educational as this site. Gentlemen- thanks for the info on the 27'er, Whaler Drive with tabs. David

Not to sound negative about Whaler Drives on the 20-25's, which I really do like, but one of the drawbacks for trim tab fans, which I am not, is that they can't be used. There is no molded in recess. So for those people who like tabs, this would be another reason to convert to a Transom Bracket on a 20-25' full transom Whaler. These will allow the use of trim tabs.

As per Bugsy on the 27', it would seem possible to fabricate pockets in a Whaler Drive on a 20-25' to carry tabs. Given the popularity of tabs on offshore boats I am surprised it has not been done. Maybe it has? One would think the tab action would be good or why would they be on the 27' which is a solid offshore setup? Thoughts. David

There is a close up picture of a Whaler Drive on a 20 Revenge in the Reference/Brackets article. I would think this would be a very difficult installation. Not something I would want to try. It would be easier to remove the Whaler Drive, install an Armstrong bracket, and then add the TrimTabs.
