5. Purge air from the fuel system. See Air

Bleeding from the Fuel System After

Starting Failure on page 34.

Changing the Engine Oil

The engine oil in a new engine becomes

contaminated from the initial break-in of

internal parts. It is very important that the

initial oil replacement is performed as

scheduled. This includes the replacement of

the oil filter at this time.

It is easiest and most effective to drain the

engine oil after operation while the engine is

still warm. WARNING! If you must drain

the engine oil while it is still hot, stay

clear of the hot engine oil to avoid being

burned. ALWAYS wear eye protection.

1. Turn the engine OFF.

2. NOTICE: Prevent dirt and debris

from contaminating engine oil.

Carefully clean the dipstick and the

surrounding area before you

remove the dipstick. Remove the

engine oil dipstick. Attach the oil drain

pump (if equipped) and pump out the

oil. For easier draining, remove the

engine oil fill cap.

3. Fill with new engine oil. See Adding

Engine Oil on page 24. NOTICE:

NEVER mix different types of engine

oil. This may adversely affect the

lubricating properties of the engine

oil. NEVER overfill. Overfilling may

result in white exhaust smoke,

engine overspeed or internal

damage.

4. Perform a trial run and check for oil

leaks.

5. Approximately 10 minutes after

stopping the engine, remove the oil

dipstick and check the oil level. Add oil

as necessary.

4. Clean the face of the filter mounting

flange and apply a light coat of oil to the

gasket of the new oil filter.

5. Install a new filter element and tighten

by hand until the seal touches the

housing.

6. Turn filter an additional 3/4 turn with a

box wrench. Tighten to 20 to 24 N·m

(14 to 17 lb-ft.).

7. Perform a trial run and check for oil

leaks.

Changing the Marine Gear Oil

Note: Refer to the Operation Manual

supplied with your marine gear or sail-drive

unit for service and maintenance details.

During initial operation, the oil is quickly

contaminated due to the initial wear of

internal parts. The lubricating oil must

therefore be replaced early.

1. Remove the cap from the filler port and

attach an oil drain pump. Drain the

marine gear oil.

2. Fill the marine gear with clean marine

gear oil. See Marine Gear Oil

Specifications on page 25.

3. Perform a trial run and check for oil

leaks.
