97 pII 200 mariner mag efi. at 3/4 throttle i show voltage at 18.6. idle 13.1. also while running down the lake the engine would just die, when i backed out of the throttle it came back to life idleing. get back into it it would act like starving for fuel. bulb hard. did this about three times. opened the tank filler cap real hard to unscrew like a vaccum had been built up. ran fine after that with the exception of the hig voltage. do i have two different problem or could they be related? could it be stator, voltage regulator, or alternator?

Unrelated issues, though the oil lines appear to be possibly pinched, or the input valve from the crank case have a clog in the laser drilled diaphragm. The crank case provides pressure to the oil tank, which pressurizes the oil into the upper reservoir. The voltage regulator appears to be out on the engine as that is too many volts there on delivery. Idle seems fine, though 18.6 on top is a wee tad much. BCB
