Guys, I baught this 96 Challenger and it had no power at all, I looked at all kind of stuff(I checked the RAVEs, I had to fixe one and adjusted them both as per the book, flush to the top, replaced plugs for iridiums, compression is ~150, cleaned spark arrester) and realised it had to do with the burning of the exaust hose... Everytime I go out to try it, because I always think the last repare should do it... I'm burning one more hose... the last one lasted about 30-45mins at med to high rev. The boat revs ~7000 and did 64Km/h on GPS. I know it could go faster but, for now I'm happy with this. Now I'm thinking the problem is all about the cooling system but everthing seam right. My last adjustment was the water flow regulator(flush to the top), because it was adjusted pretty tigh before. Now, my question is, Am'I going to burn another one of these hoses... the one between the manifold and resonator. Anything you guys could think of before I head back out and burn another one... Thanks
