Installation Guide

  1. Disconnect Power: Disconnect the battery and shift the outboard into neutral.

  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.

Sexy Comfort Casual Appeal
Size: Medium, Color: Classic Medium Wash
This is a very sexy in a comfortable easy flowing dress. The material feels good on the skin. It is thin and lightweight although long sleeves you will definitely want to wear a jacket or coat with this if you are wearing this in the winter time. It is comfortable and I like the fit on me. I am 5'5 weigh 150 and have large bust size 34DDD I ordered a medium and it fits me well. No gapping at the front where the buttons meet. I think this is a nice Jean dress for the price and the quality is nice. I like it

Cute lightweight shirt-dress
Size: XX-Large, Color: Classic Medium Wash
Flattering, but a little tight in the chest for larger bosoms, and a little short so I wore it over leggings.
