Installation Guide

  1. Disconnect the battery and relieve fuel system pressure before beginning work. Ensure the engine is cool and the work area is well-ventilated.
  2. Locate the existing motor fitting on your MerCruiser stern drive engine. Take a photo or note the orientation and connection points for reference.
  3. Using appropriate wrenches or sockets, carefully disconnect fuel lines or hoses attached to the old fitting. Have a container ready to catch any residual fuel.
  4. Remove the mounting hardware securing the motor fitting to the engine block. Keep all fasteners organized for reinstallation.
  5. Inspect the mounting surface and sealing area for corrosion, debris, or damage. Clean thoroughly with a suitable solvent and lint-free cloth.
  6. Position the new motor fitting assembly in place, ensuring correct alignment with mounting holes and fuel line ports.
  7. Install new gaskets or O-rings as required (if included or available separately). Do not reuse old seals.
  8. Hand-tighten all mounting bolts first to ensure proper threading and alignment. Then torque to manufacturer specifications in a cross-pattern sequence.
  9. Reconnect fuel lines to the new fitting, ensuring hose clamps are properly seated and tightened to prevent leaks.
  10. Double-check all connections and fasteners for tightness. Verify that no hoses are kinked or interfering with moving parts.
  11. Reconnect the battery and turn the ignition to the "on" position (without starting) to pressurize the fuel system. Inspect all connections for leaks.
  12. Start the engine and allow it to idle while monitoring for fuel leaks or abnormal operation. Correct any issues immediately before operating the vessel.

Troubleshooting & FAQ

Q: How do I confirm this motor fitting will fit my MerCruiser engine?

Must Read before Purchasing!!!! Height is lost if you use this base!!!!
Size: 100LBS
I was so very excited about this for our umbrella - and then I put it together. I called my adult son to come and take a look - I had to be doing something wrong. To our dismay, I was not. The lowest pole in the umbrella system has 4 welded pieces with holes meant to connect to the legs, thus stabilizing the structure. The lowest pole measures (guestimate) 3 feet. When you choose this system, you do not use the original cross-bars, nor the original lowest pole with the 4 welded pieces. Rather, you use a newly provided lowest piece roughly measuring a foot. In doing so, the structure loses a total of almost 2 feet. For average-height individuals, this would not be a problem. For individuals 6' or greater, this is quite a problem. My son is 6'6. My husband is 6'2. I really wanted the portability of the product. However, we will be returning it for the kind that rest on the cross-bars. I wish someone had mentioned this in the reviews I read and saved me the trouble.

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.

Croc-sational
Color: Blue
My tough chewer is OBSESSED with Croc. Stands up well, small particles occasionally come off but this beats going thru 3 stuffies in an hour. Good value, easy to clean and great for our 91lb pitty

Withstands very aggressive chewing
Color: Blue
We have a very active and aggressive chewer. Items identified for aggressive chewers are “Gone in 60 Seconds”. This toy is amazing. It has withstood Jake’s many attempts to destroy it and is one of his favorites! It is not hard like acrylic but is hard rubber with some give decreasing risk of fractured teeth. Best toy yet!!!
