hello everyone
I need a bit of help or ideas as how to go about sealing the exhaust pipe sticking out the rear of my boat.
the trouble is it needs to be able to allow me to shorten and lengthen the exhaust to find the best length of tune
for the engine,at present the tapered part is sticking through the hull so I have temporarily used silicone glue to seal it.
is there such a part like a top hat gaiter /seal which can be bought to do the job and if so where do you buy them from?

thanks for any help :help:
