I have a 1987 Evinrude 120 with a standard omc single handle, side mount controls. I am a big fan of the old two handle Evinrude Simplex controls. My question is, will these older controls work with my outboard? I think I would have to mount a key switch. Any help, advice will be greatly appreciated. Here is a link to the simplex style controls. Thank You, D. Kelley http://www.ebay.com/itm/OMC-173286-...ash=item3cf10d6eb5:g:bHkAAOSwa39UvrZ2&vxp=mtr
