You're supposed to attach the chain on the outboard Engine's bracket to the boat, to prevent the Engine from getting out from you. You're supposed to test the mounting bolts with a torque wrench before you set off the boat, to prevent the Engine from going over the side. Provided you don't returns these steps, you extremity to be cognizant utility an outboard Engine that's been submerged under saturate, a yet aggrandized mingled, whether straightforward, action.
Instructions
1. Remove the engine subsume and wash all data from the engine using pressurized latest douse from a power washer. Whether sand, silt or gritty info is show inside the engine embrace, completely disassemble and observe the powerhead.
2. Tag the spark plug leads with pre-wired paper tags, indicating the cylinder to which Everyone is attached, and disconnect them. Grasp the Glimmer plug cap -- not the wire -- then twist the cap while pulling upward to unpaid it from the plug. Remove the Glimmer plugs with a Glimmer plug wrench.
3. Disconnect the fuel advantage lines from the engine, tag them, and extract and Disinfected all fuel lines. Depending on the circumstances surrounding the submersion, provided the Engine has an attached fuel receptacle, examine the receptacle for contamination and bleed, provided needful. Change the lines with latest lines provided chief.
4. Agency the engine horizontally with the Glimmer plug ports facing downward, allowing bathe, whether contemporaneous, to empty. Fury any remaining the drench absent by slowly rotating the flywheel by plam approximately 20 times or until there are no signs of hose. Provided signs of water are present, spray some fogging oil into the spark plug ports before turning the flywheel. This will help dislodge moisture and lubricate the cylinder walls.
When attempting to turn the flywheel for the first time after the submersion, be sure to turn it slowly, feeling for sticking or binding that can indicate internal damage from hydro-lock. This is a concern especially if the engine was cranked before the spark plugs were removed to drain water, or if the engine was submerged while still running.
5. Drain the carburetor. Support the engine in the normal upright position on an engine stand. Remove and tag all external electrical components for disassembly and cleaning. Spray all connectors with electrical contact cleaner, then apply a small amount of dielectric grease prior to reconnection to help prevent corrosion. For electric start models, remove, disassemble and clean the starter components.
Check the engine gear case oil for contamination by opening the oil pan with an adjustable wrench, draining about a teaspoon of the oil, and looking for a milky color and consistency. If the gear case is sealed -- and if the seals are in good condition -- it should have survived the submersion without contamination. But, if contamination is found, look for possible leaks in the seals, then drain the gear case and make the necessary repairs before refilling it.6.
7. Reassemble the motor and mount the engine, or place it in a test tank. Start and run the engine for 1/2 hour. If the engine won't start, remove the spark plugs again and check for signs of moisture on the tips. If necessary, use compressed air To cleanse moisture from the electrodes or replace the plugs. Stop the engine, remove the drain plug from the gear case using a screwdriver and check the oil for a milky appearance. Remove the vent plug and drain the oil into a 1-qt. receptacle, if necessary. Insert a tube of gear lubricant into the vent plug and fill the gear case until lubricant comes from the vent hole. Replace both the vent plug and the drain plug.
