Boat goes into salt water slip in fall for 6- 8 weeks only. Has stainless prop. keep a floating battery charger plugged in to dock power. outdrive getting eaten up. BAD. installing mercathode kit now. If the problem was caused by shore power How will I keep battery up now that there will be a constant drain? Can I keep my charger on? will mercathode be enough to protect it? Appreciate your thoughts.
