‘Anyone with an engine cambelt needs to take special note: that will be a very expensive repair’
Here are some odds and ends I have picked up recently, starting with a boat that was eating alternator belts. The bottom of the engine pulley was badly rusted while the visible part was fine, and the rust was wearing the belt.
Anyone with an engine cambelt needs to take special note: if a cambelt sprocket goes rusty, not only will it wear the belt but the belt may stick to the rust and snap upon start up. That will be a very expensive repair.
Secondly, a boat that would not start turned out to have loose domestic battery bank interlink. This may seem odd, but the engine and domestic batteries normally share the thick negative wiring so a poor connection in one can affect the other.
Finally a reminder about winter. If you are not living aboard, drain down your water system and leave all the taps open. It is a good idea to remove any shower mixers and shake them dry to prevent frost damage.
