Troubleshooting & FAQ

How do I confirm this impeller fits my engine?
Start by checking your original part number against our cross-reference list, which includes Sierra 18-3059, GLM 89570, Mallory 9-45206, and multiple Johnson/Evinrude numbers like 5001593. Next, verify your engine model and year in the "Compatible Engine Models" table above. If you are still unsure, we recommend consulting a professional mechanic.

What are the signs of a failing water pump impeller?
Common signs include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "tell-tale" outlet, and a brittle, cracked, or deformed appearance on the old impeller's blades upon inspection.

How often should I replace my impeller?
For optimal engine cooling and protection, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of use. Replacement frequency depends heavily on operating conditions such as saltwater versus freshwater use and the amount of debris in the water.

OEM vs. Aftermarket?
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.

Better value & quality
I was using the Paula’s brand but stopped ordering because the price kept going up. This came up in my search and it’s almost the same except it has a stronger concentration & has a few more added benefits. It’s also about half the price. This product works great & I’ve been using TruSkin Vit. C moisturizer for years now so I knew their other products work for me and are good quality.

It works for my Very sensitive skin
This is the most gentle liquid exfoliant I've ever used. I have very sensitive skin and 3xs a week doesn't bother my skin at all! I Highly recommend it. DS

Bye bye ingrowns and dark spots
I love this exfoliant, I've bought it 3 times already. I use it on all my hyperpigmentation on my back, underarms, and face. It really helps with my ingrown hairs and reduces the appearance of dark spots. Super effective, I love it!

Great product!
I use this once a week. I apply with my fingertips. (It is liquid, so a little goes a long way) After you wash your face for the night- wait a few minutes then apply this. If you don’t wait it might sting for a few minutes- so wait.. Apply your moisturizer after. My face was so soft the next day after one use. It is now a regular in my skin care routine. I do not use another active like retinol or tea tree serum the day after.. just moisturizer. Would recommend and will buy again.

Good product
This seems to be working really well. I used to use a different brand of BHA and I like this one better. I do wish they had an eye dropper version, but it’s fine.
