I have purchased this filter multiple times.

First one arrived quickly and worked well. The second time I ordered one it arrived dented but they are sending me a replacement. Dented oil filters can damage your engine and should not be used even if it looks okay. The reason I'm giving 5 stars is because the product is excellent and the company was quick to replace a damaged product.

Perfect OEM Replacement

I buy one of these every fall. Quicksilver is to Mercury as Motorcraft is to Ford. It's OEM. Usually priced less than the Mercury-labeled brand.

A Quality OEM Replacement Part

We have a 17.5 foot Searay powered by a Mercruiser 3.0L inboard/outboard. It’s in good shape for its age and very reliable. I want to keep it that way. We boat on a very large lake near our home. So for peace of mind I always use OEM replacement t/maintenance parts and perform the maintenance when the factory says to, and so far it has always gotten us home.
