I have an older 35 hp mercury outboard with electric & manual start.I have no controls with ignition switch & harness.<br />Will this motor work with Quicksilver controls off a 20 hp merc,with no ignition switch?<br />Is it possible to run an ignition switch from the dash and battery cables to use elecric start?<br />I believe both motors are from the 70's.Cannot find tag.<br />Thanks.
