We were
having a wonderful week in Green island...until the generator spat
the dummy, or rather sprung a wee leak in the thermostat housing.
It's a boat!
Sitting
in the cockpit with the generator on it suddenly stopped. Opening the
engine hatch there was hissing and steam. David grabbed his head
torch and a spanner and leapt into the engine room and action. At
first he couldn't find the issue, but once the generator had cooled
he found a pin size hole in the aluminium thermostat casing, the bit
that regulates the temperature of the fresh water cooling.
At first
David thought it was going to be a major job to remove the casing. It
would entail removing the cylinder head, which would then mean
replacing the cylinder head gasket which we don't have, but after a
bit of head scratching he had his eureka moment. Rather than remove
the cylinder head he could remove the gear box end casing which would
give access to the fixing bolts on the thermostat casing.
The
get-you-home fix was to clean the corroded area and pack with epoxy
steel. However, every tube of epoxy or hole filler we had onboard had
gone off. The tropical heat and age isn't conducive for longevity.
Fortunately we have a back up generator in the garage which would
keep the batteries happy until we could get back to Falmouth Budget
Marine for new epoxy.
The long
term fix is to source, buy and import a new housing. |
