Service Manual 200-250 HP 3.3 L E-TEC Maintenance [Submerged Engines]

Once an outboard has been submerged in fresh or salt water, it must be serviced within three (3) hours of recovery. Immediate service can minimize the corrosive affect that air has on the polished surfaces of the crankshaft, connecting rods, and internal powerhead bearings.

IMPORTANT: If outboard cannot be started or serviced immediately, it should be resubmerged in fresh water to avoid exposure to the atmosphere.

Disconnect the battery cables at the battery.

Rinse powerhead with clean water.

Remove spark plug leads and spark plugs.

Place outboard in horizontal position (cylinder heads down). Slowly rotate flywheel in a clock wise rotation to work all water out of powerhead.

IMPORTANT: If sand or silt may have entered the outboard, DO NOT attempt to start the it. Dis assemble and clean.

Disassemble all electrical connectors. Clean connectors and terminals, and treat with water dis placing electrical spray. Apply Electrical Grease to terminals prior to reassembly. Coat all exposed solenoid terminals and engine grounds with Black Neoprene Dip.

Clean and inspect all electrical components. Replace damaged or corroded components prior to returning the outboard to service. Electric starters should be disassembled, cleaned, flushed with clean water, and treated with water displacing electrical spray prior to reassembly.

Disconnect fuel supply hose from outboard. Drain and clean all fuel hoses, filters, and fuel tanks.

Disconnect oil supply hose and oil return hose from outboard. Drain and clean all oil hoses, filters, and oil tank assemblies.

Refill fuel tank with fresh fuel and oil tank with recommended oil.

Prime oil system and fuel system. Refer to FUEL AND OIL PRIMING on p. 56. Make sure all oil injection hoses are clean and filled with oil.

Make sure high pressure fuel system does not contain water. Flush as needed.

Inject a small amount of outboard lubricant into spark plug holes and install new spark plugs. Refer to Spark Plug Indexing on p. 82.

Reinstall all removed or disconnected parts. Use Evinrude Diagnostics software to:

• Start break-in oiling

• Check fuel pump operation

• Check injector operation (fuel and oil)

• Check timing (once outboard is running at full operating temperature)

Run outboard below 1500 RPM for one-half hour.

Follow the same procedures as Engine Dropped Overboard (Not Running). However, if there is any binding when the flywheel is rotated, it may indicate a bent connecting rod and no attempt should be made to start the outboard. Powerhead must be disassembled and serviced immediately.

Follow the same procedures used for Engine Dropped Overboard (Not Running) and Engine Dropped Overboard (Running). Disassemble and clean outboards that have been submerged in salt water for prolonged periods of time. Clean or replace electrical components as necessary.

Outboards that have been dropped overboard and not recovered immediately, must be serviced within three hours of recovery. Follow the same procedures used for Engine Dropped Overboard (Not Running) and Engine Dropped Overboard (Running).
