Re: Submerged
From my manual:
FOLLOWING COMPLETE SUBMERSION
Submerged engine treatment is divided into three distinct problem areas.. The most critical is submersion in salt water;
the second most critical is submersion while running,
Salt Water Submersion (Special Instructions)
Due to the corrosive affect of salt water on internal engine components, complete disassembly is necessary before any attempt is made to start the engine.
Submerged While Running (Special Instructions)
When an engine is submerged while running, the possibility of internal engine damage is greatly increased If, after engine is recovered and with spark plugs removed, engine fails to turn over freely with rewind starter, the possibility of internal damage, such as bent connecting rod and/or bent crankshaft, exists, If this is the case, the power head must be disassembled.
Submerged Engine (Fresh Water) (Plus Special Instructions)
1.. Recover engine as quickly as possible.
2 Remove cowling and remove spark plugs.
3. Remove carburetor float bowl cover (or bowl).
4 Flush outside of engine with fresh water to remove mud, weeds, etc. DO NOT attempt to start engine if sand has entered powerhead, as powerhead will be severely damaged. Disassemble powerhead to clean components.
5 Get as much water as possible out of powerhead. Most water can be eliminated by placing engine in a horizontal position with spark plug holes down and operating rewind starter.
6. Pour alcohol into carburetor throat (alcohol will absorb water). Again operate rewind starter
7. Turn engine over and pour alcohol into spark plug opening(s) and again operate rewind starter
8. Turn engine over (place spark plug opening down) and pour engine oil into throat of carburetor while operating rewind starter to distribute oil throughout crankcase
9 Again turn engine over and pom approximately one teaspoon of engine oil into each spark plug opening Again operate rewind starter to distribute oil in cylinders.
10.. Reinstall spark plugs and float bowl cover (or bowl)
11.. Attempt to start engine, using a fresh fuel source. If engine starts, it should be run for at least one hour to eliminate any water in engine
12.. If engine fails to start, determine cause (fuel, electrical or mechanical) DO NOT allow engine to remain unstarted for more than 2 hours, as serious internal damage will occur, If unable to start engine in this period, disassemble engine and clean all parts and oil as soon as possible.
