I have a Sea King I am restoring . I want to install my 1956 10 HP johnson . The boat has a Smith controller . I need to replace the shift and throttle cables as they are cut. I have no idea as to how to decide what length to get /and if they will fit my Smith 2 lever control. I'm hoping someone can shed some light on how to measure for cables and possibly what cables for the Smith control.<br /><br />Thank You<br />ED
