I see a lot of dryer vent stuff used as replacements. Some in good shape, others brittle after some time and tear when moved. I don't find the same to be true for marine grade so far but everything fails after a while. I also suspect marine grade has a fire rating.

Big D, I thought the same thing, I have both out in my garage bought both on line and they both look and feel the same. Tried a burn test and they burn the same with a Bic lighter....so I.M.H.B.P.O. I'll go with dryer vent being ok...

Tony, you'd be surprised at how many marine supply places sell so called marine grade blower hose. There is no comparison between a good quality marine vent hose and regular dryer hose. The plastic is thicker, more abrasion resistant, tear resistant, oil resistant, higher temp rating, made with stainless wire, and better able to keep its diameter during installation through tight spaces. It's also about three times the cost! But like I said, I've seen the other stuff used too. Wallet dictates right? But if the benefits of marine grade are what you want, and wallet and wife allow, get the marine grade....it's for a critical system so unless you inspect it regularly, you don't want it failing and fumes venting back into the bilge for the sake of a few more bucks. Save the money on a non-critical system, and one that doesn't have safety written all over it

no argument there D, using marine or dryer hose, System checks must be done...

....System checks must be done....

Always takes me back to a guy that wanted to buy a table for his cockpit. I asked him what was wrong with the one he had. He owned the boat for several years and never knew there was a cockpit table fastened to the bottom of his engine compartment hatch Never felt there was a need to deal with anything in the engine compartment. I just can't wrap my head around that.

not to hijack ....know what you mean, we found a front window cover and aft hand rail cover on the boat that 2 owners never found still in the Carver bags.

Mine has the lookalike dryer vent hose. There is available a similiar size hose made of aluminum that is uses in exhaust hoses in buildings, usually available through HVAC supply houses, if you should want to change.

Most building codes in my are won't allow for the use of flexible white dryer vent hose for ducting bathroom or dryer vents to the exterior of the house because over time the flexible dryer hose dries out and cracks. Once the house is complete the hose is concealed and the owner could never inspect it for the cracking. So if it is not good enough to use in new construction of buildings, I sure would never put it in my boat. I would just pay the cost of the marine grade stuff and forget about it. My trojan is 34 years old and has the original hose still in great condition. I would never trust the dryer vent hose to last 10 years. Just my opinion.
