I just purchased a 2008 Cabo 38 with R6 800’s. There’s an obnoxious amount of vibration at idle throughout the entire boat, Even when it’s warmed up.. as well as troll mode. when I put the rexroth in throttle only mode, as soon at hits 800 rpms, they smooth out like a sewing machine. You barley know they’re running. The isolators are MAN and for the correct weight of the engine. Does MAN cut out a cylinder at idle and turn all injectors on at 800 rpm +? Anyone with a 38 or 40 with this power have the same vibration?
