My 40 HP Lombardini transmits a loud buzz up the gearshift and throttle cables
to the two lever head
unit. At slow cruise rpm
is quiet (at the helm) but this buzz is very distinctive, so I am keen to do something about it. I have tested by unbolting both cable mounts at the engine
; the gearshift one seems contribute the most noise
Is it realistic to mount the fixed clamp for the gearshift or throttle cables
to the boat, not the engine. This clamp to a plate that is in turn bolted to the engine, is probably where most engine internal chatter is getting in to the cables, but if the cable sheath is clamped to the boat, as the engine vibrates in its mounts, would the controls be moving too much?
The other option is to try and soft mount where the cables are clamped to the engine.
