Installation Guide

  1. Shut off the engine and close the raw water intake valve (seacock).
  2. Locate the raw water pump housing, typically mounted on the engine block.
  3. Loosen and remove the screws on the pump cover plate.
  4. Carefully pry off the cover plate and remove the old gasket. Note its orientation.
  5. Use impeller pullers or two pliers to grip the hub of the old impeller and pull it straight out of the housing.
  6. Clean the inside of the pump housing, ensuring it is free of any debris or old impeller blade pieces.
  7. Lightly lubricate the new impeller and the inside of the housing with a water-based lubricant to ease installation.
  8. Insert the new impeller by pushing it into the housing while turning it in the direction of engine rotation to bend the blades correctly.
  9. Place the correct new gasket and O-ring (if applicable for your pump model) on the cover plate.
  10. Re-install the cover plate and tighten the screws evenly in a star pattern to ensure a proper seal.
  11. Open the raw water intake valve before starting the engine.
  12. Start the engine and immediately check for water leaks and verify proper water flow from the exhaust.

Father and son both have a great imagination
Format: Hardcover, Format: Hardcover
I think Little Fox showed his father, Poppa Fox that he also some great imagination in this cute picture book by Jorma Taccone. I had to laugh as I read this book as I could totally relate to how Poppa Fox felt. As a parent, or just a human being, you feel like you’re doing the right thing, having fun and then bam, you’re thinking aww, what just happened? I thought it was sweet when Poppa Fox played pretend with Little Fox on their way home from school. Having a rough day at school, Little Fox needed something to make him happy again and his father was doing just that. Using father’s imagination, the two of them, pretended to be race cars as they raced off to the bus stop. As the night wore on, this game of pretend continued, only now Little Fox was getting more involved. What started out as a fun, friendly game was now turning violent, messy and involved, leaving Poppa Fox picking up the pieces. I liked how the book progressed from a fun friendly game to an intense involved event. I think the illustrations fit perfectly with the text as you could see this transformation and the drama unfolded right before your eyes. The text fonts were great too as they varied in sizes, shapes and colors depending on the situation. I enjoyed Poppa Fox patience as he handled the situation with his son, Little Fox. I had to laugh when Little Fox wanted his father to read to him 5,000 books before he went to bed. Now, wouldn’t that be a nice library for a child to have in their house? There is some violence in the book as they play pretend, so you may want to consider this, if that bothers you but it is pretend. I thought this was a fun, entertaining read and I highly recommend it.
