Section 5 - Maintenance

Sacrificial Anode

The sacrificial anode in the cooling system must be checked as specified by the maintenance schedule. The anode is located
at the back of the intercooler.
1. Close the seacock.
2. Place a suitable container capable of holding approximately 2–2.5 L (2.1–2.6 US qt) of liquid in a position to capture the
escaping seawater.
3. Remove the sacrificial anode.
4. Inspect the anode. If the anode is less than 10 mm (0.39 in.), it has eroded more than 50% and must be replaced.
5. Install the anode into the back of the intercooler.
6. Open the seacock.
7. Start the engine and check for leaks.

Antifouling Paint

IMPORTANT: Corrosion damage that results from the improper application of anti‑fouling paint is not covered by the limited
warranty.
In some areas it may be advisable to paint the bottom of the boat to help prevent marine growth. Contact a Mercury Diesel
authorized repair facility for recommendations for your boat.

Drive Belts

Drive Belt

All drive belts must be periodically inspected for tension and condition. Turn the engine off and remove the ignition key before
inspecting for excessive wear, cracks, fraying, and glazed surfaces.
Inspecting the belts with the engine running may cause serious injury or death. Turn off the engine and remove the ignition
key before inspecting the belts.
In the event that the drive belt requires replacement, it is recommended the drive belt replacement be performed by a Mercury
Diesel authorized repair facility.
