I have had Balmar alternators and regulators in two of my last boats. Their
MaxCharge 612 regulator is a particularly well designed unit. Get the
alternator temperature probe to protect your alternator from overheating.
Balmar's new open frame design alternators look particularly good for
improved cooling.
