Hi, We just bought a new Stingray 172SC with a Suzuki DF90. Boat and engine run like a charm.
Question: The boat is sitting now in the garage, battery switch is OFF and still every couple of min, there comes a sound from the engine, like a pump, etc. is running for 1 second? What is it? How quickly it will drain the battery? Thanks for your help, Klaus
