Troubleshooting & FAQ

How do I confirm this kit fits my engine?

Check the 'Compatible Engine Models' table and verify your model and horsepower. For Mercury engines, you can use the provided serial number guide to find your exact model details. Always verify that your existing part number matches one of the cross-reference numbers, such as 46-8M0061040.

What are the signs of a failing water pump impeller?

Common signs include the engine overheating at idle or low speeds, a weak or intermittent water stream from the "tell-tale" outlet, or a dry, cracked, or brittle appearance of the impeller vanes upon inspection.

How often should I replace the water pump impeller?

To prevent engine damage from overheating, it is recommended to inspect the impeller annually and replace it every 1 to 2 years or every 100-200 hours of use. This interval should be shorter if operating frequently in saltwater or silty/sandy conditions.

Blades are not sharp and will not remove peach fuzz, even after two swipes
Color: #10 - Pack of 21 (20 Blades + 1 Handle)
I was really disappointed in this. It did not remove all of the peach fuzz completely and I dermaplaned twice back to back. Which tells me the blades aren’t as sharp as they’re made out to be. The blade handle was sturdy and seemed to be made of good quality. But the blades themselves are horrible at cutting and aren’t razor sharp. I personally wouldn’t purchase this if I were you. I’ll keep the blade handle, but I will definitely be purchasing different blades.

Good quality!
Color: #14R - Pack of 21 (20 Blades + 1 Handle)
If you are looking to dermaplane at home obviously be careful but if you are looking into getting scalpels, these are good quality and come in a big pack where it will last you a while! Remember dermaplaning is once every four weeks and make sure you have no active breakouts!

The BEST relationship book you will ever read! Single, Dating, or Married this book will transform your relationships forever!
Format: Paperback
This book is incredible! Debra's insights as a counselor are unlike anything I have ever read and will change my relationships forever. The survey results from 1000 singles/1000 couples were really eye opening, but more importantly she presented solutions and offered hope in many areas: dealing with unmet expectations, how to be authentic, how to protect your marriage, dealing with conflict, issues with sex, how to truly become "one", and many more. Many relationship books are about a couples' journey or their advice that worked for them, Debra is unique in that your are getting perspective from a licensed counselor and relationship expert who has worked with countless clients! Her wisdom shines through and her approach to a number of subjects are so unique, refreshing, and inspiring. She does a masterful job of approaching relationships with her clinical wisdom, but rooted in her deep love for Jesus. I wish someone would have told or taught me countless things in this book years ago. I loved reading her stories of couples and singles she worked with, many real-life examples made the book very connectable and authentic. My favorite chapters were Alter that Ego, From Pride to Humility (where you actually learn what a proper apology should look like in a relationship and the power of humility in a relationship); Sex Marks the Spot, From Infatuation to Adoration (amazing chapter about navigating sex and dealing with problem spots); and Walls Will Fall, From Vulnerability to Intimacy ( If you are single, READ this book to get a front row seat into what marriage will look like and more importantly the qualities you should be looking for in your future spouse! if you are dating/engaged READ this book to learn more about your relationship, future areas and topics you need to discuss and more importantly how to handle them. if you are married (whether for a year or 50 yrs) READ this book to transform your marriage, Debra will equip you with the tools to deal with issues you may be struggling with and even more how to identity them. I walked away from this book so encouraged and filled with hope as I got a glimpse of what God's best in relationship should look like.

Choosing Marriage
Format: Paperback
I don't remember when I first discovered Debra Fileta, but she is my soul sister. Debra is a self-proclaimed realist, which is why I like her approach so much. She is the author of the site, True Love Dates. She does not beat around the bush with her relationship advice. I signed up to be on the book's Launch team, but I was quickly reminded I should not plan to do anything at the end of the school year - oops - my bad! So sorry, Debra. Better late than never, right?! I am a slow reader, but I wanted to make sure I was taking the time to gain the wisdom and knowledge Debra was sharing with singles and couples alike about relationships. Each chapter ended with reflection questions for singles and couples. Now to get to why you all should grab a copy from Amazon or your local bookstore - it is AWESOME. Worth it. I like to read relationship books because I am far from perfect and like to hear what others have to say on the subject. "A good marriage comes from a series of decisions over an extended period of time, with the commitment of two people choosing to love each other no matter what my come their way" (23). I wish people could understand this concept - and I am saying this as a single person. Even though I have seen the good, the bad, and the ugly of marriages around me, it still remains a life goal to be a wife and mother. I believe it is worth it and reading this book has given me hope that it is possible to have a good marriage. I will never truly understand marriage until I am married because "[y]ou can't experience real love with a person until you've experienced the entirety of a person - the good, the bad, the ugly, and the beautiful" (101). In this book, Debra addresses communication barriers, boundaries, and learning about good sex within marriage. She shares personal stories as well as stories from those she counseled. Debra is a straight-shooter when she states, "Seek accountability.... Get a tight rein on your thought life! Stop feeding your mind entertainment that will pollute it with lust.... [I]f you don't have a community, it's time to turn off Netflix, get off social media, and start investing in real-life relationships with godly people" (175). Ouch. That applies to singles and couples alike. Debra's last chapter called "The Beautiful Exchange" could be a book itself, comparing the seasons of a year to seasons in marriage. I guess it is how you view each natural season how you would compare it to marriage, but it's a challenge to think deeper about the ebb and flow of life seasons. "Marry someone who will make you better" (184).
