Salt Water Ingestion
Salt water is far more aggressive than fresh. When it gets into a marine engine — through a failed riser, a back-flooding exhaust, or a swamp — it begins corroding cylinder walls, valves, and bearings almost immediately. The window to flush and preserve the engine is short. Keeping the engine off and getting a technician to it quickly is the difference between a flush and a rebuild.

What to Look For
Raw water reached the cylinders, intake, or oil
A back-flooding or corroded exhaust riser
Engine was swamped or submerged in seawater
Rusty water on the dipstick or at the plugs
Common Causes
Riser / manifold failure
The classic marine petrol failure — raw water siphons back into the cylinders.
Exhaust back-flooding
A low transom or slow cranking lets exhaust water reverse into the engine.
What to Do — and What Not to Do
Do
- Keep the engine off
- Note the water source — salt vs fresh
- Call 0800 769 000 immediately
Don't
- Start, crank, or run the engine
- Attempt to burn off contaminated fuel by running it
- Top up the oil or fuel before the system is assessed
- Motor the vessel back to the ramp under its own power
- Pump contaminated fuel overboard — it is an environmental offence
