flush after every use. ....mercruiser has ceramic coated @ 250.00 ea. for manifolds and 150.00 for riser's there is one company that sells stainless manifolds and riser's @ $1600.00 each about the cost of a long block 5.7.

In other world need buy new to make treatment of coating efficientl.

Bingo ....or deal with it like everbody else does buy new risers and manifolds every 5 yr's depending on usage.

Welcome aboard !

Mani's not so, can last 20 years or more elbows yes every 5 years if you boat in saltwater.

You get 20 yr's out of a ex manifold in saltwater !!!! :rolleyes: I thought they stop making space shuttle manifolds

Trouble with most "rust resistant" coatings is that they insulate ... best way is to get a FWC setup and find some NOS factory S/S risers - shame they made it to the NLA list!
