Reduce fuel pressure

Warning:

Make sure to reduce the fuel pressure in the fuel line before maintaining the fuel line or

high-pressure fuel pump. Otherwise, high-pressure fuel will be sprayed out, causing injury or
accident.

Disconnect the joint of oil pump power supply connection line.

Start the engine.

Note:
Run at idle speed until the engine is cut off.

After the engine is turned off, turn the flywheel to rotate the crankshaft 2 or 3 times.

Warning:

Do not turn the flywheel counterclockwise to avoid damage to the valve mechanism.

Turn the outboard motor startup switch to OFF.

Connect the joint of oil pump power supply connection line.

Check the oil filter cup

Before removing the oil filter cup, place a rag at the lower part to prevent spilled fuel from

flowing around.

Disconnect the joint of water detection switch.

Disconnect fuel line.

Remove the nuts securing fuel filter assembly.

Remove the oil filter cup.

Remove oil filter cup holder.

Use a vacuum manometer to check whether the oil filter cup leaks.

Specified pressure: 80kPa

7.

Check whether the filter screen is blocked or there are sundries in it, and check whether the

filter cup is damaged or leaked.

    Note:
    If necessary, clean it with gasoline or replace it

Re-mount the oil filter cup

Note:

Before reassembling the filter cup, apply engine oil to the O-ring.

Removal and inspection of fuel pump

Remove the bolts securing the fuel pump.
