John, you should expect your new exhaust system to last a lot longer
that 5-7 years. I don't expect to ever have to do this job again on my
boat.....the hoses I used are guaranteed for +10 years, the muffler is a
Vernalift resin.....the old mixing elbow I took off was used by me here
in salt water for 7 seasons and it did not need to be replaced (neither
did the SS muffler)....obviously they were changed before we bought the
boat in 2006 but I didn't know that, so I replaced it all.
Agree, the hardest part was the 18" short piece of hose from the mixing
elbow to the muffler.....on my boat the hose has to be bent down of
course, but with a slight " S " in it as the mixing elbow outlet is not
lined up with the muffler intake...thus the need to " S " shape the
hose...and it doesn't want to be shaped that way no matter how much heat
your apply to it.

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.

Yes, I did remove the mixing elbow and exhaust flange together from the
exhaust manifold......it was the only way to remove the mixing elbow....and
then it was challenge to separate the mixing elbow from the flange on a work
bench....but with patience and a little help of a pipe extension on the big
wrench, it separated.
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,
Working with exhaust hose can be very challenging. When I replaced
mine, I used 90 degree fiberglass elbows. It was far superior to the
kinked mess my boat came with. They are much easier to put together
than a long piece of stiff hose. I usually remove the mixing elbow
along with the exhaust manifold. It's much easier to put them in a
vice on my bench than try to separate them on the boat.

Problem with changing the mixing elbow was the limited and awkward
space to work in on my boat......access is in through the port locker
into the engine compartment,,,,access is restricted because of hot
water heater in the port locker (could be removed but I didn't, extra
work).....mixing elbow in on the starboard side so I am lying on my
right side using my left hand.....I am 'right handed'.
Ended up taking the mixing elbow off by working from the front of the
engine. A friend had done it before and helped me. He had "blank(s)"
or "bolts without heads" that could be screwed into the exhaust
manifold to guide and hold the mixing elbow in place while you
attached the permanent ones. Doing that 'blind' from the front of the
engine or trying to do it with one hand would be almost impossible.
Then attaching the hose from the mixing elbow to the new Vernalift
muffler proved to be a challenge......used a heat gun to soften the
hose....just difficult to work with one hand much of the time.
