I have a 2009 Hurricane Deck boat with a Yamaha F150 4 stroke outboard. I have power to all the switches and accy's but am losing power to the starter when I try to start. Battery is putting out 12+ volts, but when I check volts going into the starter, it drops down to around 3 volts. I assume the problem is either in the ignition (fuel pump engages and there is a click at the starter when I attempt to start) or in the wiring harness. Any ideas on how to test these or what the problem may be?
