NOTE
Hydrostatic lock is caused by the entry of substantial amounts of
water into the engine through the air intake system and
subsequent contamination of the fuel system. Hydrostatic lock most
frequently occurs during or just after fording. Water is forced into
the air intake system, is drawn into the engine, and effectively
locks up the engine.
Notify unit maintenance if you suspect hydrostatic lock and they
will test the engine.
