The previous owner replaced the muffler with a metal car muffler which blew out and is now discharging water to the inside. I have found a replacement fiperglass muffler but it looks almost imposible to reach the exsisting muffler to replace. Can anyone help with replacement instuctions?

Hire a contortionist!
You can get the wall between the quater berth and the engine compartment out to provide easier access to the muffler. But you will have a hard time getting some of the aft screws back in once you get them out. The other way is to put a pad on top of the engine, and lay/squirm over it until you can get ahold of the muffler fittings. Not easy in any case! David Lady Lillie

Technique for H30
I don't think your boat should be much different from my 1980 H30 so here is what I did. I disconnected the aft end of the exhaust hose from the stern thru hull exhaust fitting by reaching down into the stern lazarette. I then disconnected the forward end of the exhaust hose from the end of the mixing elbow on the engine. Laying on top of the engine, as suggeted, you can pull the entire exhaust system (all hoses and muffler) forward and out from beneath the fuel tank and batteries. You can measure and replace the hoses and the muffler and install new clamps. Then slide the whole thing back over the engine and into the original position. Whew!

Just did mine
I replaced my leaking stainless steel muffler earlier this season, with a new fiberglass one. After trying to get the old one out via the starboard cockpit locker (maybe this would work if I had removed the fuel tank)and by attempting to remove the bulkhead behind the engine, I finally took out the panel next to the quarter berth that David mentions. The "difficult" screws closest to the stern -- accessible only from the muffler area! -- had already been left loose by previous owner. Some of the screws on the cabin end of this panel were difficult to find; I ended up loosening or removing a piece or two of the teak forming the engine enclosure frame to access these screws. Once this panel was out, it was easy to crawl into the aft berth and replace the muffler. Also take this opportunity to check out the wheel steering (if you have it) and the coupling on the rudder post. I found two nuts on the bolts mounting the steering pedestal to the cockpit floor were missing -- found them in the bilge and replaced.

Need to do same on my 789 H-27
I have to do the same on my H-27... removing the panels on the quarter bearth is the way to go... I've had to remove them to reah the stubbing box and do some shaft work. I have the old Yanmar 8 HP... What muffler did you purchase?
