I am installing a "crows nest tower", no controls as it must be removed to trailer, on top of my hardtop for site fishing. I can steer by wireless remote from the auto pilot but want to add a kill switch on the tower, with lanyard to use, just in case. This will only be used at idle speeds while searching for patchreefs etc. The boat is rigged with twin Honda 135's. Does anyone know of a aftermarket kill switch that can be use with twin outboards or some other method of doing this? Honda will sell only the entire switch panel with new ignition swiches. Thanks.
