Checking the cooling water pilot hole
1. Place the lower unit in water, and then
start the engine.
2. Check that cooling water is discharged
from the cooling water pilot hole. If there
is no water flow, check the cooling water

Checking the engine idle speed/
noise
1. Start the engine and warm it up for 5–10
minutes.
2. Check the engine idle speed using the
Yamaha genuine tachometer (on-board
meter) or the YDIS. See the YDIS (Ver.
2.00 or later) instruction manual.
Changing the engine oil
The engine oil should be extracted using an

Change the engine oil after the first 20
hours of operation or 3 months, and every
100 hours or at 1-year intervals thereafter.
1. Place the outboard motor in an upright
position.
If the outboard motor is not level, the oil
level indicated on the dipstick may not be
correct.
2. Start the engine and warm it up for 5–10
minutes.
3. Stop the engine and leave it off for 5–10
minutes.
4. Remove the oil filler cap “1”.
