Rob, I have the identical boat and replaced the entire exhaust assembly and essentially went through all the moves that you did working from behind and then in front of the engine. The hardest part was the short hose interfacing the elbow with the muffler and I had a problem removing and reconnecting. There doesn't appear to be any short cuts unless you are willing to cut off the interface hose and replace it with a new one. I just did this job last season and should get 5-7 years out of it.

My friend that helped had 'headless bolts' can I could hand screw into the exhaust manifold to guide the combined exhaust flange and new mixing elbow in place. I put two in diagonally, put the other two diagonal permanent bolts in, removed the two 'headless bolts' and put the next two bolts in....tighten up....done. It helped when you are working on your side left handed. Also put in a new gasket between the flange and manifold. There was no problem with the exhaust hose from the muffler back to the thru hull...other than standing on my head working on the thru hull connection. The problem was connecting the short 18" hose from the mixing elbow to the muffler......because of the angle to the two and the stiffness of the 'marine grade hard walled exhaust hose' I chose, for a long time I could not connect the hose over one of the two.....the angle and stiffness of the hose and the fact I am not able to work with both hands adequately, made it a frustrating job....I could get one on but not the other. After multiple attempts, I attached the hose to the mixing elbow and inserted a big flat head screw driver into the hose, which gave me the leverage to bend it enough to begin to place it over the muffler intake....a few tries with the screw driver, success........ and it was now beer time. As with every first time job, if I were to do it again (which I hope I never have to), I could do it with more know how and less frustration. Rob Abbott AZURA C&C 32 - 84 Halifax, N.S.
