2002 Sea Ray 340 Sundancer with twin Mercruiser 6.2 MX MPI motors with 500 hours, having this issue above 3,000 rpm. Marina service has set timing, replaced cap & rotor, spark plugs and wires and they can not figure out this issue. Batteries are new, new alternator, fresh fuel (in fact they replaced both inline filters and water/separator filters) and this issue persists.
