Installation Guide

  1. Disconnect the battery cables at the battery for safety.
  2. Unbolt and carefully remove the sterndrive's lower unit from the upper gear housing.
  3. Locate and remove the bolts securing the old water pump housing. Lift the housing off the driveshaft.
  4. Remove the old impeller, wear plate, seals, and gaskets. Thoroughly clean the mounting surfaces of any debris or old gasket material.
  5. Install the new driveshaft seal and wear plate.
  6. Slide the new impeller key into the driveshaft and install the new impeller. A light coat of marine grease or soapy water can ease installation.
  7. Place the new water pump housing over the impeller and fasten it securely with the bolts.
  8. Re-install the lower unit onto the upper gear housing, ensuring the driveshaft aligns correctly.
  9. Reconnect the battery and start the engine. Check for proper water flow from the tell-tale port to confirm the cooling system is functioning correctly.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my engine?
A: This kit is specifically for OMC Stringer drives (400 & 800 series) from 1962-1985. It is not compatible with OMC Cobra drives. Please cross-reference your engine model and year with the 'Compatible Engine Models' table and verify your original part number against our 'Part Number Cross-Reference' list.

Q: My engine is overheating. Could the water pump be the cause?
A: Yes, engine overheating at idle or low speeds is a common symptom of a failing water pump impeller. Other signs include reduced water flow from the exhaust or tell-tale port. Regular inspection is recommended.

Q: How often should I replace my water pump components?
A: For preventative maintenance, it is recommended to inspect the impeller annually and replace the entire water pump kit every 1-2 years, or every 100-200 hours of operation, depending on usage conditions (e.g., saltwater vs. freshwater).

Q: Does this kit include everything I need for the installation?
A: This kit includes the primary components: the housing, impeller, wear plate, key, and seal. Depending on your engine's condition, you may need additional gaskets or O-rings which are not included. Always check your service manual for a complete list of required parts.

American Bully Trial - Honest Review
Color: Cyan NylonFish
I have never gotten a toy that lasted more than an hour when it comes to my baby girl. She is an aggressive chewer and loves anything that squeaks. This definitely helped to keep her entertained and use her teeth. I can confidently say that this toy may last a long time but she has already ripped a piece from it. I didn’t expect anything less since she always knows how to test new toys lol. I would definitely recommend though and will be getting more for her once this one is gone. Thank you!

Hard, heavy, sharp
Color: Cyan NylonFish
This is very durable, but it is also very heavy (our dog likes to throw her toys) and after some chewing, the head and tail are very sharp

2 years later and it’s still going!
Color: Cyan NylonFish, Color: Cyan NylonFish
I have 2 dogs, a 6lb chihuahua (Lolli) and an almost 100lb German shepherd/Belgian Malinois (Uzi). Got this for Uzi, however, Lolli had other plans for it. She literally took it out her mouth and ran to hide it. It’s been over a year, closer to 2 and it’s still hanging on. Attached a photo of Lolli…

Color: Cyan NylonFish
I have a heavy heavy chewer, the only things that has escaped him were items like "kong" solid and rubber but no squeaky. He quickly lost interest in the toy; largely within a week at most and never picks it up again unless really bored. Squeaky toys had a life shelf of a week at best, that is with us taking them away to "preserve" them for longer. So far, this toy, the fish, has been the longest surviving squeaky and the longest at keeping his interest. it has received some cosmetic damage, but nothing that would make you remove the toy from his possession and it STILL squeaks.

Still holding up to my super-chewer!
Color: Cyan NylonFish, Color: Cyan NylonFish
It's a very good product. I would recommend this toy for a heavy chewing dog. My main reasons it's not 5 stars, it's HEAVY and the eyes peeled right off. My pup really likes to throw his toys around, this thing sounds like a cannon ball that's going to go through our floor! He also tries to destroy everything so he was chewing on the eyes and he would have definitely eaten them if I wasn't paying attention. It's not a horrible thing but I obviously don't want him to eat non food things. My dog also likes the squeaker in it, but it's difficult for me to get it to squeak. That's not a big deal though just thought I should mention it. Overall especially for the price, it's a good sturdy product that's cute and it's still holding up. He's chewed parts of the softer areas off a bit, but the rest is very hard so he hasn't made much of a dent. It's also about as big as his head, so he's pretty happy with it!
