I have a 150 hp 2005 Yamaha TXR. Recently I rewired the entire boat and upgraded the switches. Everything works, including, the Yamaha gauges and engine trims except for the engine itself. I turn the key and the kill switch in place. I can hear the carburetors opening, but nothing is happening to the engine. Dead. I overpassed the ground terminal in the engine and it tries to turn, but it just won’t. All the fuses in the engine have continuity.
