Inspection

Inspect your power package often and at regular intervals to help maintain its top operating performance and correct potential
problems before they occur. The entire power package should be checked carefully, including all accessible engine parts.
1. Check for loose, damaged, or missing parts, hoses, and clamps; tighten or replace as necessary.
2. Check electrical connections and leads for damage.
3. Remove and inspect the propeller. If badly nicked, bent, or cracked, contact your Mercury Diesel authorized repair facility.
4. Repair nicks and corrosion damage on power package exterior finish. Contact your Mercury Diesel authorized repair
facility.
It may be necessary to remove the engine cover during some maintenance inspections and procedures. To remove the engine
cover:
1. Lift and detach the engine cover from the mounts.
2. Set the engine cover over the mounts and press the cover down in the mount areas to reattach the engine cover.
