Four Winns 2004 have a Volov Penta 280hp I/O. Repowered 4 years ago with a Four Winns dealer.
Ran beautiful for about 200 hours. Has developed a skip at first was only after a cold start. Once warmed up skip was not present. Recently has been more constant warm or cold skip is present.
Coils have been changed, distributor cap changed, rotor changed plugs changed, fuel filter changed, fuel pump changed.
Diagnostic tool does not pick anything up.
Mechanic has two trains of thought
Exhaust possible blockage or valve /head issue.
Has anyone else had this concern and what corrected the issue?
