Inspection

Inspect your power package often and at regular intervals to help maintain operating performance and to identify 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 it is 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.
