Black on SS Prop

[luckyinkentucky]

I have a SS Shooter prop on my 94 Vindicator, and after a decarb last week I noticed it was black around the outside of the prop after the process was done. Does this mean I have an exhaust leak somewhere around the prop shaft? It's black on the inside, and has some black around the outside where the prop meets the housing.

Re: Black on SS Prop

your exhust discharges thru the prop,the additional black is the carbon that the treatment has cleared,you fine,it may take a while to clear,but note,its normal to see black from exhust
