Manley Performance “PRO SERIES” stroker crankshaft designed for the Gen III small block HEMI engine. Manufactured from a premium 4340 steel forging, these cranks feature a 4.050” stroke which can turn your 5.7L into a 392 c.i. engine and your 6.1L/6.4L into a 426 c.i. engine.

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
