Installation Guide

Follow these steps for proper installation. Ensure the engine is off and the battery is disconnected before starting.

  1. Safety First: Turn off the engine and disconnect the boat's battery power.
  2. Locate and Remove Old Anode: Identify the existing trim tab anode on the lower unit. Use a socket wrench to remove the central mounting bolt. The old anode may be difficult to remove if heavily corroded.
  3. Clean Mounting Surface: Once the old anode is off, thoroughly clean the mounting surface on the gearcase. Ensure a clean, bare metal-to-metal connection for proper electrical continuity.
  4. Install New Anode: Position the new aluminum anode onto the mounting surface.
  5. Secure the Bolt: Insert the new mounting bolt and tighten it securely according to the manufacturer's torque specifications. Do not over-tighten.
  6. Final Check: Confirm the anode is firmly in place and does not wobble. Reconnect the battery.

Troubleshooting & FAQ

Q: How do I confirm this anode fits my engine?
A: First, check the "Part Number Cross-Reference" table to see if your existing part number is listed. Next, review the "Compatible Engine Models" tables to find your specific engine model, year, and serial number range. Verifying both is the best way to ensure correct fitment.

Q: How often should I inspect or replace my trim tab anode?
A: It is recommended to inspect all anodes at least once a year, or more frequently if you operate in aggressive salt or brackish water. Replace the anode when it is 50% corroded to ensure your engine remains protected.

Q: What is the advantage of an aluminum anode over a zinc anode?
A: Aluminum anodes are more active than zinc, providing superior protection in a wider range of water conditions, especially in fresh and brackish water where zinc can become passivated (form a coating and stop working). This anode is suitable for both fresh and salt water use.

Q: What are signs that my old anode has failed?
A: A working anode will show signs of corrosion and pitting over time—this is normal. However, if you notice rapid or uneven corrosion on your sterndrive or outboard's lower unit, it means the anode is no longer providing protection and must be replaced immediately.

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.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.

I’m a little disappointed.
Format: Kindle
I usually like Jillian West’s books but this one was missing a lot for me. The pregnancy didn’t come across as real. She’s on her feet for 12 hour days but is perfectly healthy at 8 months pregnant? Yet the week she moves in all of a sudden she’s not? She is planning on actually running during one of the plot buildups. But at 8 months pregnant that’s incredibly hard to do. The lack of breathing ability and lung space, the change in body center, mass, and gravity. All of it prohibits running, unless you’re an athlete this didn’t come off as at all realistic. I didn’t feel any connection with the alphas. There wasn’t any emotional connection. It could be because of the tense it was written in. But I didn’t get any deep feelings out of this. It came across as checking off boxes. Even the spicy scenes weren’t really believable for me. I wanted to see them fall for her, and it just kind of all fizzled. Even Bishop. One thing I did really like was the ending. I did not see it coming and I’m interested in reading book two because of it. But on the whole this book was mostly disappointing for me.

Vale is an 8 month pregnant omega working as a waitress at a strip club and a cam girl. She starts to get very creepy vibes from a regular at the club, and her baby daddy ghosted her. She has had an online relationship with a man named Bishop through her cam girl status. One night, bishop was paying to watch her sleep and ansthe creepy regular Andrew break in and watch her sleep he tells vale to come to him at his business now. She flees and finds herself at a large security company with some.hot of alphas who are there to help her. This imegaverse is a little different than I have read, but I am thoroughly enjoying it. Vale is not a traditional omega she was raised by a single beta mom, and the alphas are not normal alphas they have never really loved pack life. But they are ruthless mercenaries. They need her, and she needs them. I love the aspect of the stalker and now the plot twists at the end, so so good. Sometimes, it seemed a little slow and stale mated, but since this a duet, I think It was just her starting to have Vale get to know her alpha suitors. Cliffhanger for sure with this one.

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol
