Hi,
Two year old MErc, bought new, well serviced, Merc 2018 60 hp CT on an18 foot Pontoon.. I recently noticed a slight whine at approx 1800 RPMs. Idle and Full throttle and other RPMS perfect. If running just under plane at Approx 1800 RPMs, I hear a slight whine from the engine. Dropping down or over 1800 Rpm it's gone. Any thoughts?? Anything to worry about? EFI Pump noise ?? Harmonics of RPM? Thanks - just trying to be proactive with a new sound ... SteveC
