Billet & Stainless Serpentine Belt Crossover for Mercury 454/502 Magnum MPI
|
|
At last you can finally
purchase a crossover for your serpentine belt driven EFI motor.
Until now there was no way to reap the 15 to 20 horsepower gain that
could be achieved by removing the unnecessary power robbing circulating
pump. These beautifully polished crossovers allow you to retain
your factory serpentine drive belt through the use of a clutchless
freewheeling billet idler pulley. This unit is a perfect addition
for any EFI motor. If you want great looks and performance while
retaining your OEM drive system, then this product has you covered.

This kit represents one of
the cleanest installations of a water inlet crossover system found
anywhere. The highly polished 316L stainless steel construction
locates all of the necessary hose connections in the perfect location
for easy installation. This system uses a large 1" bypass hose for
increased water volume...no tiny 5/8" stuff found here!
Eliminating your power robbing circulating pump has never been easier or
more attractive.
