I have noticed a water leak at the bend (goose neck) in the rubber flexible exhaust pipe, the pipe was changed 8 months ago using Loyds spec. pipe. Would it not be better If I used a plastic elbow attached to the pipe as it seems that this is the weakest point as I can see the pipe vibrating here wih the back pressure of the exhuast. The pipe is clipped at intervals to the hull to make it rigid as seen on other Beneteau boats. It seems that where the pipe is kinked due to the elbow is very vulnerable to breaking. Any suggestions Please. Mario
