I have a 1985 16' Invader w/ a 90 horse Johnson and an OMC ignition. I can't find the keys and am trying to replace the switch. I find many a switch w/ 6 flat terminals with holes in the flat part, while mine has round terminals that look like little posts. There is a reciprocal female connector on the short wires and very little room to work with in the throttle unit. Does anyone know where to get the RIGHT ignition switch? Thanks. Keith
