Chris Schuster –
OEM replacement on my 5.7L Merc. I have a bravo 3 out drive, so it is located at the bottom front of the engine. It took 15 min to swap. Bought an extra one just in case, might as well for 15 bucks! A service center around me charges $100 for this job. Save your self $85 by doing it yourself.

Replacement for Mercruiser impeller………appears to be of similar quality. I have previously used Sierra/Teleflex parts and found them to be good replacements and respectable savings.
Lin Holt –
fit was good but they will only last one season at best 3 months
Williamsburg Dave –
Perfect replacement fit. I have twin 5.7 Mercruiser inboards on my SeaRay, and I swap out the impellers once a season. Easy job once you get the hang of it, and cheap insurance! Carry a spare or two.
Josh A –
Perfect fit. Item as described. I will be replacing this annually from now on!
Michele Bullard –
As expected

Genuine Sierra part. Fit perfectly. It’s been in the boat and doing its job all season.

I change my impeller every 2 years. Second time purchasing. Good quality. Could have gotten an extra 1-2 years out of it.
