Installation Guide

  1. Safety First: Disconnect the boat's battery and ensure the engine is completely cool before starting.
  2. Access the Area: Gain clear access to the sterndrive's exhaust components. This may require removing drive components or panels.
  3. Locate Old Bellow: Identify the old lower exhaust bellow connecting the exhaust elbow and manifold.
  4. Remove Clamps: Loosen and remove the hose clamps securing the old bellow at both ends.
  5. Remove Old Bellow: Carefully pry or cut the old bellow away from its connection points. Clean the surfaces of any old adhesive or rubber residue.
  6. Position New Bellow: Slide the new exhaust bellow into place, ensuring it is seated correctly on both exhaust components.
  7. Install New Clamps: Place the new stainless steel clamps over each end of the bellow.
  8. Secure Clamps: Tighten the clamps securely to create a watertight seal. Do not overtighten, which could damage the bellow.
  9. Final Check: Once installed, double-check that the bellow is straight and not twisted or pinched.
  10. Reconnect and Test: Reconnect the battery. After reassembly, run the engine with a water supply and check thoroughly for any exhaust or water leaks around the new bellow.

Bigger, louder, crinklier, softer, than expected!
Size: X-Large, Color: Rabbit
My dog was gifted a collection of used toys and he really likes a very long stuffed pig which, unfortunately, another dog that is a destructive chewer, totally destroyed. I decided to break down and buy him another long stuffed toy today and since he's always blissfully watching rabbits in the yard and neighborhood I chose the rabbit version. This thing is huge which is great for him- he's 62 lbs and 7 months old and only half grown. He loves it, it has multiple LOUD squeakers, lots of crinkly spots, and fun ears/legs to grab hold off. He's a big fan and it's made with K9 Tuff Guard which LASTS. Super soft and easy to wash. Update after 2 months- easy to wash and looks new after a washing. very durable so far, standing up to indoor and outdoor use. He is not a destructive chewer but whips them around, tramples on them, steps on them while running top speed and chomps on the annoying squeaker for hours. one squeaker has a hole and its tune is now slightly muted (thank god)

Won't last forever, but my dog loves it
Size: X-Large, Color: Giraffe
My dog, a 90 lb black lab, LOVES these toys. He does prefer the raccoon to the giraffe, but he likes them both a lot. I originally got the raccoon on clearance at Target when looking for a long toy he could play with while he was in a cone recovering from surgery (he likes to be able to hold toys between his front paws and mouth/chew on them, so none of our regular squeaky footballs were long enough for that). He loved it so much I had to find more, so I found this giraffe from the same line of toys. He's a destroyer and he has been able to put a few holes in these toys if I'm not watching him, but they're pretty easy to sew if they need patching. My mother-in-law's dog came over and made a hole so big that the squeakers and lining all came out, but I sewed it back up and it's almost as good as new. They definitely won't last forever, but they have lasted longer than other soft toys we've had in the past.
