Mercury 565 Manual page 69

Operating the engine out of the water at high speeds creates suction, which
can collapse the water supply hose and overheat the engine. Do not operate
the engine above 1400 RPM out of the water and without sufficient cooling
water supply.
IMPORTANT: Change the oil only when the engine is warm from operation.
Use only the recommended motor oil, see Specifications.
1. Provide cooling water to the engine.
2. Place the remote control into the neutral position and start the engine.
Operate the engine at idle speed, in neutral, until the engine reaches
normal operating temperature.
3. Stop the engine, shut off the water, and remove the flushing attachment.
4. Remove the bilge plug. The oil drain hose is tethered to the plug.

7. Using two wrenches, separate the oil drain hose plug from the oil drain
hose and allow the crankcase oil to drain until empty.
8. Place a container below the oil filter.
NOTE: To allow the oil to drain from the filter, loosen the filter enough to break
the internal vacuum. Let the oil drain back into the system for 15 minutes prior
to complete removal of the filter.
9. Remove the oil filter from the adapter and discard the old oil filter and the
old sealing ring.
10. Coat the sealing ring on new the filter with motor oil. Install the new
sealing ring and filter. Tighten the filter securely. Do not overtighten.
