    WTB: MSX140 Exhaust expansion pipe

    Hi everyone,

    I had a leak in the hull for some time now. I have been tracing it and after replacing all the hoses and driveshaft seal it was still leaking.

    The culprit was the cast expansion pipe was crack and pissing water out. I thought ok, i will just weld it up. I v grooved the crack and pulled my tig out and welded it up. When I pressure tested it, the crack was in the exhaust jacket as well as the water jacket.

    So my question is has anyone got a 2004 polaris exhaust expansion for sale and willing to post it to Australia?
    (A perfect one with no cracks in it)

    I had the same problem last summer with my 04 MSX140. I had it welded twice and it developed leaks in different locations. I was lucky enough to find a member on here with a used one, and put 30 hours on it since with no issues. Good luck.
