Risk of water entry. Close the seawater cocks before
doing any work on the seawater system.
The seawater system must be drained during cold
weather when there is a risk of freezing to prevent the
system from bursting. An alternative to draining is to
keep the engine room free from frost using an
approved heater fan.
