Replacement of heater duct

[Isaguel]

I need to replace the flexible duct from the heater coming onto the cabin area. The one that came with it is a cheap, thin plastic that has torn, i've already taped it once but it keeps tearing, I would like to get something thicker/more durable. I have found some on amazon but am not sure if it will be a perfect fit. Anyone had to replace these? WHere did u buy it?. I don't have my boat with me to look but I would guess the diameter is about 3 inches.

Yeah, mine is in rough shape too. I haven't done it yet, but I've seen others on Facebook saying RV sewer hose fits well. I measured the diameter of mine, it was 3.25" dia iirc.

Try searching “black bilge ventilation hose” I found a few other options around $1 per foot.

Anyone has any videos of how to get to the end of the hose to replace it?
