Does the 1988 Yamaha 40 hp charging system include a voltage regulator? Volt meter reads 12.6 volts with engine stopped and 16 volts at cruising speed. Voltage increases with engine rpm. Marine battery is installed. Planning to replace OEM rectifier with CDI rectifier/regulator (157-664-61) to maintain system voltage level at a reasonable level. Wanted to check for similar experiences.
