Date Last Tested (DLT) not to exceed 12 months.

Initial Inspection/Disposal Criteria

  1. Visually inspect for evidence of use (dust, oil, starter seal broken), damage or missing parts.
  2. Return to stock if there is no sign of use or damage and date last tested (DLT) does not exceed 12 months.
  3. Refurbish as necessary if unit has been used or fueled, damaged, or shelf life is exceeded.
  4. Dispose of the unit if it is not economically repairable.

Refurbishment Procedures

A. Cleaning

  1. Remove dirt and oil, using detergent or degreaser as necessary.
  2. Use pressure washer to remove heavy deposits of oil and grease.
  3. Equipment should be repaired and tested as quickly as possible after pressure washing to minimize rust formation on metal parts.

B. Repair

  1. Check for loose and/or missing parts or mounting hardware; tighten or replace as needed.
  2. Ensure recoil starter functions properly. Check for damage or fraying of pull cord; repair or replace as necessary.
  3. Inspect power-head (engine) for freeness of all moving parts, ensuring that the crankshaft, piston/cylinder and all engine bearings are not damaged.
  4. Check condition of spark plug, air filter, and fuel filter; clean or replace as needed.
  5. Inspect exhaust system; make sure there are no cracks or leaks. Check for loose or missing mounting hardware, tighten or replace as needed.
  6. Check throttle float. Make sure all pieces are present and the float moves up and down freely.
  7. Make sure there are no holes in the boat.
  8. Check water intake for debris (weeds, sticks, etc.).
    • Make sure that the intake screen is in place and securely fastened.
  9. Ensure all decals (operations & warning) are affixed and legible.

C. Test for Performance

  1. Pumps are tested using a 1½” discharge and a 1/4” nozzle.
  2. Set idle speed to 2400 RPM manually hold throttle float down.
  3. To adjust high speed: Using full throttle, lean out high speed adjustment screw to achieve maximum RPM, then richen until pump output pressure drops 5 PSI. Minimum output pressure: 100 PSI.
  4. Should any function fail a test, refer to the manufacturer’s repair manual and troubleshooting guide to correct the problem.
  5. Allow engine to cool down for one minute at idle.
  6. Remove all gasoline from fuel tank and run engine until carburetor is completely empty of fuel.
  7. Remove all water from pump end.

D. Repackaging

  1. Use nylon “zip-tie” to tie off (seal) starter rope to the carry handle.
  2. Attach certification tag; that indicates date last tested (DLT), property #, and name of individual certifying performance.
  3. Ensure that all identification (property #, serial #, owner ID) is affixed and legible.
