Installation Guide

  1. Safety First: Disconnect the boat's battery before starting any work.
  2. Access the Pump: Remove the stern drive's lower unit to access the water pump assembly.
  3. Remove Old Pump: Carefully unbolt and detach the old water pump housing from the lower unit. Note the orientation of all parts.
  4. Clean Surface: Thoroughly clean the mounting surface on the lower unit, removing any old gasket material or sealant residue.
  5. Install New Components: Place the new gasket and stainless steel wear plate onto the lower unit.
  6. Insert Impeller: Apply a small amount of lubricant to the new impeller and insert it into the new housing, turning the driveshaft clockwise to bend the vanes correctly.
  7. Mount New Housing: Secure the new housing assembly over the impeller and bolt it down to the manufacturer's torque specifications.
  8. Reassemble: Reinstall the lower unit onto the stern drive.
  9. Test: Reconnect the battery. Start the engine in the water or with a proper flush attachment and check for strong water flow from the tell-tale outlet and for any leaks around the housing.

Troubleshooting & FAQ

Q: How do I know if this kit will fit my OMC Cobra engine?

A: Please check your engine model and year against the detailed compatibility chart above. This kit is specifically designed for OMC Cobra stern drives from 2.3L to 7.5L (model years 1986-1993) and directly replaces OEM part numbers 984461 and 984744.

Q: What are the symptoms of a failing water pump impeller?

A: The most common signs include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "tell-tale" outlet, or a high temperature alarm sounding. Upon inspection, the old impeller may have cracked, brittle, or broken vanes.

Q: How often should I replace the water pump impeller?

A: As a crucial part of preventative maintenance, we recommend inspecting the impeller annually and replacing it every 1-2 seasons or 100-200 hours of operation. Replacement frequency depends on usage and water conditions (saltwater, sandy, or silty water can accelerate wear).

Q: Is this an OEM part?

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?

A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?

A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details.

Great tasting
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
I ordered both the wagyu beef and the venison . Just received them today. I’ve only tried the wagyu beef so far and I’m very impressed. It’s not overly salty and more like a dried hamburger beef. Not to dry to need a flosser like other Jerky’s. The venison is way to salty I definitely prefer the Wagyu

The best meat sticks!
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
These are the best meat sticks I’ve found so far! They are very clean and go down well. Very tasty. If you need more protein on the go-these are a no-brainer. Slightly pricey, but worth it!

Not bad. Read the box.
Flavor Name: Wagyu Beef Steak, Size: 0.8 Ounce (Pack of 10)
First of all, this isn't really beef jerky and nowhere do they state that it is. Simply put, it is not your typical beef jerky. I don't know how these are processed because there are not nitrates, nitrites, or even celery powder - which are the ingredients used for curing meat. Yes, these are ground and formed meat strips, just as it says on the box and on each individual strip wrapper. These lack all the extra preservatives and additives that other strips and jerkys have. And although some of the other meats that they have are flavored with cranberry, apple, or bacon, these don't have much flavoring at all. Just added honey, which keeps it from being totally vile. When I first opened the package, the scent was that of old time (not ancient) jerky. The way jerky looked and tasted in the 70s. But the flavor is really meaty/bloody tasting, with little hint of honey that makes it palatable. I'm not hating on this, it's rather not really too bad... just gotta get used to that bloody raw meaty taste. I've had their beef/bacon/cranberry bars and those were not edible. They were totally disgusting. Maybe it's because these are thinner and more like jerky (you get less of a mouthful) that I find them easier to swallow. I'v had quite a bit of their "bacon" bars (note, they are bars, not strips), and really wish they'd make the bacon bars thin like these strips as well. Although I like the bacon best, sometimes it's just too much... it's like spam but not as tasty. The texture of these is much better. Bottom line, if you expect these to taste like O'berto stips, then don't get them. If you expect something that tastes like a caveman's dinner, then this is it.

Meh
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
This is not beef jerky but rather and "ground and formed" meat snack. Not particularly rich, not particularly flavorful, and thus not particularly Wagyu.
