Boat - 2003 SAN
Engine - PCM Excalibur 5.7L
Boat runs rough at idle and will slowly creep on plane and up to speed when not loaded down. There is also a strong fuel smell coming from exhaust.
I have replaced plugs, plug wires, cap/rotor, and fuel filter. Cleaned spark arrestor. Checked fuel pressure - 60psi.
Seems I may have a sensor issue, but I hate to start throwing parts at it. It is also very difficult for me to get the boat to a dealer to run a diagnostic test.
This is my last ditch effort before taking it to a dealer. Any ideas? O2 sensor?
