Will this work on a 1990 70hp evinrude? I see no key switch or a place to plug in my wiring harness?
It is a universal control unit for all single-station outboards and sterndrives with mechanical transmissions. It does not work with OEM cables though and you will need the 3300/33C cables for these to work. This has no key switch. For more info call us at the number at the top of the page.
Will this control work with my 1995 50hp Johnson outboard motor mounted on my 1988 20 foot Fiesta pontoon boat ?
This is a universal control that will work with most outboard/sterndrive engines and replaced side mount single controls. It isn't specifically for the boat you have listed, but should work with it, along with various boats of that nature.
