Exhaust repair

 I cut off the insulating bandage of the lower section of the exhaust and noted that there was no flexible section in the exhaust - this means that the exhaust is being stressed by any engine vibration. I noted that the original exhaust that looks about 4mm thick from the manifold had been sleeved with cheap bendable pipe and had been riveted to the manfold pipe. The cheap pipe had sheared at the end of the overlap section and was only held in place by a thin thread. The cheap corrugated pipe was 45mm. I went to midland chandlers and would have had to replace the whole system with screw fitting pipe and manifold, including a flexible section. In the end I decided to go for a cheaper temporary option of a repair sleeve available from a motor factors. The sleeve has substantial pair of bolts and I put some repair putty in the joint - clean break to assist the seal. After tightening I put more putty around the edges. On starting the boat I noted it was a lot quieter and I will be less embarased to cruise now as it was very noisy at high revs. I then replaced the bandage on the exhaust after checking for leaks. A good day and I hope the repair last for the rest if the year. The battery isolation is working as the boat started first pull.

I also bought a battery operated pump to empty the bilge fully as the bilge pump leaves about 1.5 inches of water in.
