Dead exhaust - how to change flex hose

Hello Community.

based on what I have seen in the most recent threads, I am not the only small sailor facing rusty exhaust at the beginning of the season...

Recap: I was given that boat 2 years ago. A 1977 Catalina 27, gas A4, likely original to the boat. My beloved engine is a first class rust bucket, with 2 plugs that have resisted the yearly change for the past few years...

So transfer from dry marina to the wet one last week, it was quite smokey inside. Afraid that it was oil cooking or similar from the engine, I dive inside and start looking for the source of that light smoke. Quickly realized that this was a nice smell of exhaust gases including a good share of CO. After a few minutes of happily breathing it, I ended up feeling a warm flow of gases coming out of the "insulation tape" on the exhaust pipe. Once back at the marina, I take a cutter to remove it (I hope it is not abestos...), and start cutting it out. And there surprise, the blade goes right through the tape, directly INSIDE the pipe. The insulation was holding the 2 pieces of pipe together!

Anyway, i am not the first nor the last one to suffer that. After a couple hours of forum navigation and reading previous people experience, I get to the marina fully geared with tool boxes to try to remove that, praying that no bolt would break in the block... luckily, the last owner to touch that system had stainless bolts used. They agreed to come out after some time and convincing arguments. There is a God for small boat owners

So that thing was really dead

Then, only after all pieces come out nicely, I call Ken at MM and buy the pre-made piece. I just do not have the time to run after the different pieces at the hardware store...

So this is where I need your help guys: from the exhaust manifold to the end of the previous exhaust piece (where now my flex hose (the one going to the transom) is waiting for a new male friend, I have around 30 inches. Ken confirmed me that their new piece is around 18 inches long... so I am short 10+ inches on that big flex hose pipe.

If I want to do that repair properly, I need to change that flex hose for a longer one: I am not fat, but I am 6'3, and there is no way I can squeeze myself through the small hatches, rotate 90° and be able to get to the end of that pipe on the transom. So here is my question how the f***** is one supposed to change that flex hose? My only solution is to send my 7 yo daughter, as I tried to convince my 40 yo wife, who is the same size, who told me there was no way she would go/creep in that dirty oily place...
Any other solution?

the back-up solution is to insert a 10" long piece of flex-hose with a middle nipple...

Thank you!!!
