    Default Pull out heater hose upgrade

    My 2020 Mojo pull out heater ducts didnít make it one summer. The unreasonably thin membrane rubbed through over the spiral wire and now they are leaking air out the hose. SC will only replace it with the same paper thin membrane that it left the factory with. The hose on my 2008 Mastercraft is still perfectly intact and we use it all the time.

    Has anybody else experienced this and what product did you use to upgrade from factory?

    Do these come with a thicker membrane than the OE tubes and do they attach to the heater with no modifications? The site doesn’t list any dimensions.

    Look into RV sewer hose. It's a lot heavier duty and you can get a 25' roll from Walmart for like $10

    Heatercraft is the OEM so i'd wager they are the same paper thin crap.
    Mastercraft uses Maradyne

    I just ordered maradyne stuff to add a heater o my boat so I can tell you in a few days when it gets here.

    I looked into this for my Mojo, but then was concerned about how it would work. The hose has to able to collapse into that small space. A thicker hose might not and cause the vent to pop out all the time. My hose was torn at the end where it attached to the vent. I just cut the torn part and reattached it.

    Never had an issue with mine and we use them often, however, I found some thicker mil hose awhile back, let me see if I can find it again

    I have both tears and itís worn over the spiral wires. I live in northern Canada so these are a heavy use item.

    Thanks for all the replies. Lots of good leads. I let you know how I make out.
