Looks very good quality to me.
Size: 85-300 HP
Everything looks good quality to me. I find it odd that the people leaving bad reviews with pictures of broken and melted impeller, when you can clearly see the brass on the inside is brown and dirty like old pennies and mine is shiny new. It's almost like the took the pictures of the ones they replaced to get a refund and a free repair kit.

Well made materials.
Arrived on time and well packaged. Good quality materials and exact fit. Perfect fit, Easy to install. Make sure to review installation instruction. Don't put the gaskets in the wrong place. Will buy again from this vender.

Good for the $$$
Worked great on my Mercruiser Alpha One Gen 2. Once the bottom unit of the outdrive is off and cleaned it only takes a few minutes to install impeller, seals and housing. A very affordable alternative to taking it to the shop.

Fit perfectly and very complete set of parts
Had everything I needed plus some extra parts in the kit. I probably could have just replaced the impeller for slightly less but while everything was disassembled you might as well replace the works. Included - Water Pump Impeller, Housing, Key, Face Plate, Face Plate Gasket, O-Ring, Seal Face and Carrier Assembly Oil Seal
