possible cause.
Valve Lash Check
Corrosion
This can occur when two different metals are in
contact near to, or in, sea water. For example, a brass
or bronze pipe tted into aluminium can cause rapid
corrosion. For this reason, special precautions are
necessary when an engine is installed. In this situation,
some components will be connected to a sacricial
anode tted to the hull. Specialist manufacturers will
advise on the maintenance of these anodes.
Supplementary tools
A general tool kit and an on-board repair kit
are available from your Perkins Distributor. It is
