Package Contents

  • 1 x Intercooler Zinc Anode (Replaces Yanmar P/N: 119574-18790)
  • 4 x Heat Exchanger and Oil Cooler Zinc Anodes (Replaces Yanmar P/N: 119574-44150)

Installation Guide

  1. Shut off the engine and allow it to cool completely. Close the relevant seacock.
  2. Locate the existing zinc anode plugs on the heat exchanger, intercooler, and/or oil cooler.
  3. Use a wrench to carefully unscrew and remove the brass plugs.
  4. Remove the old, corroded zinc pencil from each plug. Use pliers if it is worn down significantly.
  5. Clean the threads on the plug and the engine housing to ensure a good connection.
  6. Thread the new zinc anode into the corresponding plug until it is hand-tight.
  7. Apply thread sealant to the plug threads and reinstall it into the engine housing.
  8. Tighten the plug securely with a wrench, but do not overtighten.
  9. Repeat this process for all five anodes in the kit.
  10. Once all anodes are replaced, open the seacock.
  11. Start the engine and carefully inspect for any water leaks around the newly installed plugs.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific Yanmar engine?
A: The surest method is to cross-reference the OEM part number 119773-92600 with your engine's service manual. You can also check the "Compatible Engine Models" table on this page. Please note the specific exclusions, such as most 4LH series engines and the 4LH-STE 230 HP model.

Q: My engine setup seems to require five small zincs, but this kit only has four. Why?
A: This kit contains the standard four small anodes (119574-44150) and one large one (119574-18790). However, some Yanmar engines paired with a ZF transmission cooler require an additional small anode. You must verify if your transmission requires a separate anode and purchase it if needed.

Q: How often should I replace my engine's zinc anodes?
A: Best practice is to inspect anodes every 3-4 months and replace them when they are approximately 50% consumed. The rate of corrosion depends heavily on your boat's usage, water salinity, and any stray electrical currents.

Q: OEM vs. Aftermarket?
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?

The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.
