    Testing the 470 Charging System

    Solar Power Anyone????

    I had trouble starting my port side motor. Now that I got it to start and run I have coolant shooting from the 2 side ports on the lower portion of the gimbel housing. Can this be the water hose or does seawater only flow through that hose? Thanks!
