Planned on a beautiful afternoon sailing on Jan. 1 in Port Aransas, TX. Prepped boat for engine start. Battery switch on, coolant seacock opened. Key inserted and gauges reacted. Voltmeter read 12+. Lit glow for 15 seconds as usual. Hit start button and voltmeter reacted but nothing from engine. No turn over at all. Heard clicking sound from engine compartment that stopped as soon as I turned the key off. Anyone have a clue what's going on? Thanks and happy new year!
