Now you can conveniently start or stop a Yamaha EF4500iSE (55-6999) and EF6300ISDE (55-6986) generators by remote control using the wireless remote start/stop switch on the easy-to-carry key fob transmitter. The remote uses encoded transmissions so you can prevent false operation from other signals. Automatically activates the choke, so you can even start a cold generator with ease. Easy to install - just plug into the connector on the generator's wiring harness and mount securely inside the generator. 1/pack.
