2003 Volvo Penta Turbo Engine With A Leaky Water Pump

This 2003 Volvo Penta Turbo engine housed inside a Westerly Riviera sounds like it needs a hot water bottle and a Lemsip.
This engine is definitely under the weather as the customer reported that along with its raspy cough it also has a leaky water pump. If it could talk it would ask for a sick note and some Lucozade.
