I own a Mercruiser 7.4mpi motor which I beleive is between 310hp to 330hp. I currently have standard Mercruiser exhaust manifolds and they exit through the propeller. I do not have an exhaust through the transom and I intend on never changing the exhaust configuration.
I am about to buy the Procharger 5psi kit which Procharger claim will provide me with 500hp and good reliability. My question is will my standard exhaust be ok? Will I have any reliability issues (water reversion) if I keep this exhaust long term?
