Questions regarding a Stainless Marine exhaust swap!
Right now, I'm having the old Mercruiser exhaust manifolds (which actually are actually reusable even after 16 years!) swapped out in favor of a set of Stainless Marine manifolds and risers.
Since everyone I'm talking to says I'll pick up 2-300 RPMs and all over performance and fuel economy gains, is there any thing else I should do; i.e. timing adjustments, prop adjustments, plug gap etc... Right now, everything is set to stock!
The boat is a 1990 Formula 292SR1 with twin (stock) 454 mags (360 hours).
Thanks
