Big Shrimp, Specifically, the Lenco Tabs use one electric motor per tab and are outboard mounted directly to the tab.
Bennett tabs use a remote mounted electic pump that sends hydraulic fluid out to the corresponding tab. I agree the actuators are hydraulic on the Bennett but the motor that drives them is electric. I knew what you meant but a novice might be misled there.
I have had both. Both gave me problems. It is a boat, that is its job.
Lenco tabs seem to be more prone to corrosion and motor failure. Bennett tabs are tough to beat like you said. The trouble I am having with the Bennett is I have one that won't retract.
Having the space to mount the Bennett pump might be a deciding factor when it comes to trim tabs. Lenco tabs just have wires running from the tabs thru the transom up to the controls. My .02

usually when you have a bennet that won't retract, either teh line is crimped or the hose nipple is threaded in too far on teh cylinder. Loosen teh fitting on the hose niple for the tab that won't retract, if it comes up, its in the line or the pump, if it doesn't, trun the hose nipple about two turns out and see if it raises. If you install teh hose nipples too far in the bennert cylinders, it will cover the transfer hole to the cylinder, it will let fulid by under high pressure, but it won't let it out

Curious as to which would be better: Bennett M120's or the traditional 12x9's? Do any of you have experience or opinions about the differences?
