  4. Remove the two mounting screws securing the sender switch.
  5. Remove the old sender unit and clean the mounting surface thoroughly.
  6. Position the new trim limit sender and secure it with the original or new screws. Do not overtighten.
  7. Connect the new wire leads. Use the included adapters if your boat has older-style ring terminal connectors.

Troubleshooting & FAQ

Q: How do I know if this trim sender kit will fit my MerCruiser drive?
A: This kit is compatible with MerCruiser MC-I, R, MR, Alpha One (Gen I & II), and all Bravo stern drives that use analog gauge instruments. Please check the "Compatible Engine Models" table to confirm your model uses the OEM part number 805320A03.

Q: What are the common symptoms of a failing trim limit sender?
A: Common signs of failure include an inaccurate or non-functioning trim gauge, the gauge needle jumping erratically, or the drive trimming up but not stopping at the preset limit.

Q: My trim gauge doesn't work, but the drive still trims up and down. Is the sender the problem?
A: This kit contains both the trim limit switch (stops the drive) and the trim position sender (for the gauge). If only the gauge is failing, the sender portion is likely faulty, and this kit will resolve the issue.

Good read
Format: Kindle
The book has some good twists and turns, but truthfully I was so confused on some things. It didn't have a good flow for me personally. Not sure if it's due to typos or using him/her wrongly, but I thought Kelly was both a guy and a girl. Actually I still don't know, and it made me incredibly frustrated. It would refer to Kelley as him or he, and then again in another part of the story as her she and sister. On to the next book, I hope there is some clarity and a smoother flow. This is a slow burn, and I just don't know how much I care for the Alphas yet. Idk if I recommend.

the lies
Format: Kindle
This is amazing fast pace read that is full of plot twists and lies that keep getting bad. This is a story we’re a omega has been lied to by her mother and finds out that someone is slowing dieing. 3 alpha take the omega and feed her more lies so they can use her against her father so they can find their mate Kelly. This is a dark read and ends in a cliffhanger and so good.

Ends in a cliffhanger
Format: Kindle
Thankfully, the next book is already available. Roxy Collins is the queen of omegaverse slow burn. This particular series is omegaverse with wolf shifters. Thoroughly enjoyed this book! Lots of suspense and trying to figure out what is true and what's really going on. I loved it! Pretty spicy once the action starts. Heats are pretty much always spicy. There is a little bit of male interaction, but not full-on shmex. Definitely recommend.

Epic!!!!
Format: Kindle
Absolutely addicted from the first page. The twists and turns, world building and character development all come together for the perfect Omegaverse. And let's not forget that spice because knots are life and these are spectacular. Running for book #2 because that cliffhanger was torturous.
