I have a bit of a problem and don't want to just do this haphazardly but would appreciate if someone could explain how to add a remote button starter. I'm trying to work on this motor by myself (wife has had enough of me bugging her as my key turner) & it is a bit difficult to turn the motor over to test spark, electrical etc, when one has to be at the key on the remote console. So I guess the question is --- I've seen 12v starter button accessories at places like Harbor Freight Tools...will that work and how do I attach it or is there something better for marine apps. Thnx
