  2. Check all running lights.
  3. With the boat off the trailer, inspect either bunks or rollers for excessive wearing, broken board, torn carpet, or loose or missing bolts.
  4. Both bearing and brakes if applicable should be serviced by a certified mechanic yearly.
  5. A good coat of wax once or more a year will help in both looks and longevity of your trailer.
  6. Check the level of electrolytes in all batteries. Add only distilled water and fully charge after every use. Check battery post for corrosion.
  7. Inspect fuel systems for any odors, leaks, or deteriorations.
  8. Do steering systems work smoothly both ways? Grease the steering cable if needed. Look for any loose bolts and signs of deteriorations.
