Vessel: 1998 Formula 330 SS with twin 7.4 MPI's with Bravo III's and about 360 hours on each. Boat has 1 battery selector switch with Off, 1, both, and 2 selector options.
Issue: Boat starts and idles great. When I give it throttle in gear, both engines accelerate but quickly lose RPM while simulataneously the voltage meter jumps from 13.8 up past 16 volts.
Troubleshoot: I ran the boat in 1, 2, and both options of the selector switch chosen and the issue remained the same. I ran the boat with no accessory switches on and the issue remained the same. I checked for a loose ground connection at the batteries (2) and at the battery bus bar. I checked the back of the selector switch for a loose connection. I check the 12V panel board for a loose connection. Everything appear to be tight and not corroded.
Question: Has anyone else had a similar issue and/or does anyone have any suggestions or ideas as to what could be causing this issue and the best way to remedy the situation.
Thanks in advance for the help.
