Underway the boat is getting noisier and vibrating. Checked the prop shaft to gearbox gap all within 10 thou. Cutlass bearings renewed 3 years ago BUT when in neutral tickover is fine, as it revs to 1200rpm the engine shakes/vibrates and steadies at around 2200rpm. Does this point to sagging engine mounts? The engine is a Cat 3116TA mounted on Barry pin mounts. thanks in advance. Geoff
