  3. Separate Gearcase: Carefully lower and separate the gearcase to expose the water pump assembly.
  4. Remove Old Pump: Unbolt and remove the old water pump housing, impeller, and wear plate. Take note of the blade direction of the old impeller.
  5. Clean Surfaces: Thoroughly clean the mating surfaces on the gearcase and driveshaft, removing any old gasket material or debris.
  6. Install New Components: Place the new gasket and wear plate onto the gearcase. Install the new impeller key onto the driveshaft.
  7. Install New Impeller: Slide the new impeller onto the driveshaft. Turn the shaft clockwise while pushing down to correctly orient the blades inside the new housing cup/liner.
  8. Secure New Housing: Place the new housing over the impeller assembly and secure it with the provided screws, tightening them evenly.
  9. Reassemble: Re-install the gearcase, ensuring the water tube, shift rod, and driveshaft are properly aligned.
  10. Final Tightening: Tighten all gearcase bolts to the manufacturer's specified torque.
  11. Test Operation: Reconnect the battery and test the engine in a suitable water source, confirming a strong, steady stream from the tell-tale outlet.

Stability with food on it!
They were a bit small than I had thought, but perfect for little tidbits for parties and church fellowships. Attractive and clean looking, held snacks just fine.

NICE for soups!
Style: 34 Ounces, Size: 34 Count
We try to keep these in the house. They are REALLY nicely sized and work great for soups. They are AWESOME for soups and the only disposable plates I feel comfy using for large stews and such. Makes cleaning easy because I don't HAVE TO CLEAN! They are a bit more expensive than otherd disposable plates, but they are worth it. Pretty heavy duty plates that are thick and great for heavier foods. <3
