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

Good quality, but could have used better instructions

The kit was complete, and all the components were well made. However, if you aren't somewhat mechanical, it would be fairly easy to install the gaskets and backing plate in the wrong sequence. With better instructions, this would be a 5 star plus kit.

Don't pay boat shops for over priced services!

Boat shop wanted $400 dollars for a new water pump replacement. Got this on Amazon and watched a few utube videos. Took less then 2hrs to take apart and replace. I put it in a Alpha 1 gen 2 lower. Very simple process.
