i just bought a 1998 wt17 tracker targa and it came with a 12 volt 48 pound thrust bow mount trolling motor. the old fella i bought it from said "i never could make that d--- thing work right!!!!" well its my guess it isnt big enough for the boat. so here is my question. it says in operators manual that boat is either wired with a 12 volt or a 12/24 volt wiring harness for the trolling motor. it also says that that wiring is independent of everything else. how do i tell if it is wired 24?? id like to put a bigger trolling motor on it. thanks for any help you may offer.
