2001 Yamaha 90 hp 2 stroke with 135 hours. Runs well
Electrical problem: Installed 2 new marine batteries. Voltage when running at 3500 rpm is 12.9--13.o
At night, if I turn on the two 55 watt halogen dock lights, the voltage goes to 11.7, sometimes to 11.2.
Do I have a problem with the charging circuit?
So far, the motor has not failed to crank and runs well.
