Faults and Fixes
The engine temperature spikes underway — what should I do first?
Reduce revs and, if necessary, shut down; pushing a hot engine turns a cooling fault into head and gasket damage. Then check the raw water circuit: seacock, strainer, impeller.
Why it works this way
A single overheating event changes the remaining life of an engine and leaves an entry in the ECU. That record is read during a survey — it is one of the most valuable pieces of history a buyer can get.
