Boaters enjoying the advantages of Helm Master EX can also enjoy Yamaha’s battery-management system, which brings a serious dose of tech to powering up. The key fob allows you to turn the juice on and off; a pair of 12-volt batteries is all it takes to crank up to five outboards. The system prioritizes charging the starting batteries first before feeding the power over to house batteries. Added bonus: A state-of-charge indicator on the engine displays or MFD lets you check on the state of your batteries at any time.
