Installs in place of your factory crank pulley. Free's up some nice HP. Zetec motors are INTERNALLY ZERO balanced, meaning the factory pulley IS NOT a harmonic dampener of any kind. This means swapping the crank pulley will have NO adverse effects on engine longevity, Massive’s staff has logged literally over 500,000 collective miles with these pullies installed and have seen NO unsatisfactory qualities. Weight differences between this and competitors pulleys is less than 2 ounces yet pulleys offer 90% higher total rigidity and far better overall strength. Fairly straight forward installation, comes with instructions. Should take less than 1 hour for a novice car guy (or girl). Pullies come anodized MASSIVE PURPLE. Has the Massive logo and a crank position mark machined into the faces.

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

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.
