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.
