Trim tabs?

So I think it's time for trim tabs on the 7m. With the big single I get some serious lean and people get tired of being moved around as ballast. It would be one less thing to think about and going really fast with a bit of a lean is not comforting. There seem to be two big brands, any significant difference between them? Bennett and Lenco?

How big do I need? I have to go measure what I have room for so that might narrow it down.

What's involved for install? Do they "just screw in" or do I need to thru bolt the mounting? Holes thru the transom for hoses or wires?

Thanks
Jason

Bennets are hydraulic & I think Lenco are electric our bennets are through bolted & the hydraulic pump is inside the boat with the hoses through the transom
It's not just a case of one thing less to think about though it's actually someting else to think of ours are fitted to a cruiser which tends to lean into a side wind which takes a bit of input to keep it level as the wind angle changes with course changes
Maybe different with a rib
It might be worth looking at alternative props as some props claim to help the prop torque lean

I've got Lectrotabs on BP. Raising the engine helped greatly with the lean, but the tabs allow me to get perfect trim, especially in a beam sea. They also allow you to keep on the plane easier in rough head sea conditions. Takes about 1/2 a day to fit. They screw straight to the transom, with woods crews/ self tappers. I think my tabs are 8x12".


.....sh1t happens.......

The difference is the 30lbs of having my son or my wife on one side or the other. Not anything worth doing with props. I can adjust it with people or even me moving a foot or so to a side at the helm but it would be nice not to. Yesterday we came home and they switched places and so we were listing a bit but we were doing 40 mph (15gph @4900rpm) so it made for a couple hops where I was thinking about the landing.

Lencos have always worked well for us. I would go for a 12" wide tab that come 9" out from the transom. Easy to fit with no hydraulic hoses to worry about just two twin wires that go from the tabs back to the console. Its worth getting the LED Indicator switch so you can see the position they are set in.

They were showing the new Bennet trim tabs off at Seaworks, they've gone away from hydraulic & brought out an electric version.

Trim tabs (like a lot of Boating add on's) are not essential....But once you've got em ....nice to have!
