On a 1972 53 MY, I originally had four 8d 8volt batteries in two battery boxes port and starboard. The starboard batteries are a real pain to check and top off.

I have a three year old Raymarine navigation system (C90w) and for the last few months when I turn it on it does not acquire the vessel position or depth. It does no good to turn it on and off but if I throw the breaker to the whole system, it works fine on start- up. Any recommendations before...
