Losing rpm on port engine only.
Ok guys here we go, I have twin 350s and 1 fuel tank. I am losing rpms on port engine only when I throttle up to 4500rpm. both engines run at 3000rpm but this is not enough for this boat. I have replaced these items so far.
1. Both water seperators
2. coil on port side
3. fuel filter inside carb on port engine
Now I am contemplating changing cap wires and rotor. I am open for suggestions.
Boat has 435hrs 1996 Maxum 3200SCR
