Hi does any one have one of the old style choke switches for the yamaha 703 ,the one that fits between the ignition and kill switch,not push to choke on the key
Any non latching "normally open" switch will work.
The fun bit is finding a waterproof(able) one!
I have used maplin's big toggles on my panel for nav lights etc - they have optional rubber boots and so far I have had 6 years with no issues...... Granted you might not physically fit one inside your 703, but I moved my electrics out to the console for ease of maintenance etc.
