Hi everyone, I just picked up my new Century 2102. Boy is she sweet, but it came with Lenco Trim tabs installed. It doesn't have the LED lighted switch (yet). Could someone please explain to me what these are for and how they are supposed to be operated. The boat package is a 21'8 center consol stile thats powered by a F150 Yamaha 4-Stroke and the package weighs about 3,200 lbs. Any help would be nice. Thanks
