I have a 98' Mercury EFI 150HP on an 18.5 ft doral bowrider. The problem i'm experiencing is when I throttle down occasionally the engine will just cut out, as a result of my volt gauge dropping right off and then my ignition alarm sounding for low battery. I have two brand new batterys in the boat which are grounded to each other. I'm thinking it is somesort of wiring issue as the boat starts and runs fine aside form this random cutting out? Any suggestions?
