1991 703 contols. Had a 1991 175 Yamaha on my Grady 190 Tournament and just repowered it with a 2001 Ox 66 150HP. The original control has the separate choke. Obviously, the choke is non functional as this is a fuel injected motor. The gauges will not turn off when the switch is off. I suspect the switch is bad. Does not appear that the original switch without the choke is available non-oem. Since the choke will not be functional, is it possible to replace the switch with the push to choke switch as they are available non-oem at one forth the price. Will the switch wiring be the same, and just not wire up the choke?
