Installation Guide

  1. Safety First: Before starting, disconnect the engine's battery and ensure the outboard is shifted into the neutral position.
  2. Remove Lower Unit: Carefully unbolt and remove the lower unit assembly from the outboard's midsection. Be prepared for it to be heavy.
  3. Access Pump Housing: Place the lower unit securely on a workbench and remove the bolts securing the water pump housing.
  4. Disassemble Pump: Lift the old housing off the driveshaft. Slide the old impeller, keys, and wear plate off, taking note of their order and orientation.
  5. Clean Surfaces: Thoroughly clean all mating surfaces. Scrape away any old gasket material or corrosion to ensure a proper seal.
  6. Install New Components: Install the new wear plate gasket and wear plate. Insert the new impeller key into the driveshaft.
  7. Install New Impeller: Slide the new neoprene impeller onto the shaft, rotating it clockwise to help seat the vanes inside the housing cup correctly.
  8. Secure New Housing: Place the new housing, gasket, and other seals into position and secure them with the new bolts, tightening them to the manufacturer's specified torque.
  9. Reinstall Lower Unit: Carefully reinstall the lower unit, ensuring the driveshaft, shift shaft, and water tube are properly aligned.
  10. Test Operation: Reconnect the battery. Using a flush attachment or in the water, run the engine and check for a strong, steady stream from the water indicator (tell-tale) port to confirm correct operation.

Troubleshooting & FAQ

A: Please review the "Compatible Engine Models" table above. Cross-reference your outboard's brand, horsepower, stroke, and year range with the information provided to ensure a precise match.

A: Common symptoms include the engine overheating, a weak or intermittent water stream from the tell-tale (water indicator) port, or discovery of brittle, cracked, or deformed impeller vanes during a visual inspection.

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

I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Okay I’m usually not one for stand-alone’s I’m an avid series reader but my goodness am I so happy I read this! This story was brilliant & so absolutely mesmerizing. I loved reading about each character and their struggles as well as what helped them to move forward. The ending definitely brought tears to my eyes so hard. I truly wasn’t expecting some of what happened in this story. There is about to be a spoiler I am going to reveal so please stop reading if you don’t want the spoiler !!!! ⚠️ ⛔️ ‼️ I loved that the author didn’t do what most authors do with irredeemable male characters. I truly was hoping that Nate Jr. would be apart of the pack after the way he treated Astrea bc he truly didn’t deserve it. Though I must say you did a wonderful job or redeeming him as a person. I cried my eyes out when he walked into the story. I was truly terrified he was going to be a bad guy to the end. However you truly did him such a justice by having him realize his faults & having him redeem himself in the most wonderful way. I’m so sad that he didn’t get to hear how much his brother loved him & forgave him before dying. But again you wrote that ending so beautifully & I just can’t express how much I loved this story & how you took a different route than most authors I have read have. You are a remarkable author Cinder Blaze & I thank you generously for creating such a masterpiece.
