 |
|
 I have a 350 mpi in a ski boat. It performs well in all respects except for an annoying vibration that comes though the whole boat at different revs.Mainly 2 3000.I have renewed the prop shaft, skeg bush and had the prop checked.I feel it may be caused by the exhaust pipes resonance as the pipes touch the hull. Any comments ? Mark. |

Even though you checked it...
Shaft (and anything related) - or perhaps engine mounts. I do not think the exhaust...
