Dealing with a melted exhaust (without an exhausting meltdown).<\/div>\n

These photos were sent recently by our friend Dave Wyman. Dave was on a delivery from Hawaii to Puget Sound aboard a Beneteau 50 recently when the salt water pump impeller failed. This allowed uncooled exhaust gas into the Vetus plastic aqualift muffler, resulting in a melted connection and failure of the aqua lift itself.<\/p>\n

While this could have happened at any time, Murphy was at work as they had just made it to the Pacific high’s area of weak pressure and were ready to start powering – after bashing their way to weather for 600 miles.<\/p>\n

The skipper decided to head back to Hawaii.<\/p>\n

On the way back a bandage was fashioned from Marinetex and fiberglass cloth. This worked well enough that they were able to power the last six hours into harbor.<\/p>\n

There are several lessons here:<\/p>\n

    \n
  • Before a long passage, if the water pump impeller is out of date, however that is defined for your engine, replace it (we do ours once a year). <\/li>\n
  • Aqua Alarm makes two forms of sensors that can be used to detect overheating. One is a band which is attached to the exhaust hose. The other is a sensor which goes in the salt water hose feeding the cooling pump. Either of these would have alerted the crew to the problem before the damage occurred.<\/li>\n
  • This is not an uncommon failure. Carry a repair kit and perhaps a spare coupling, and some extra exhaust hose clamps, from which you may be able to fashion a bandage.<\/li>\n<\/ul>\n

    The last photo Dave sent was of this system for holding extra fuel jugs to the life lines. It is a piece of 2" square (50mm) timber, u-bolted to the stanchions. There are ten jugs on each side. That’s about 400 pounds (180kg) of diesel port and starboard .<\/p>\n

    Our first reaction was that this was not a good thing to have on deck. But Dave said that through 600 miles of sailing up hill, and then returning, everything stayed in place.<\/p>\n","protected":false},"excerpt":{"rendered":"
