Good info...thanx. The motor is a stock OMC 454 similar to a 330hp Merc. Mercs manifold might be the trick as Im sure there are plenty lying around garages. The friggen exhuast manifolds are just so damn pricey and I prolly wont see any performance increase from my motor. I would like to sell the boat and eventually get an outboard sportfisher but with moving this year and going back to school full time, toys are on hold
