Exhaust hose advice

Postby john26 » Fri Apr 07, 2017 8:33 am

I desperately need to replace my exhaust hose, it is flat and dry rotted.I am going to us trident corrugated and want to know how bad of a job this is.Looking for advice from the experts.
Can I safely do this in the water?

John, I've replaced sections from engine to mufflers and it was hard to get off and tight to put on. Had to cut off with sawsall. If your exhaust is below waterline you might flood the boat when you replace the last piece .

If flooding's a possibility, how hard would it be to plug the opening on the outside during repairs?

I replaced mine with shields marine...look on ebay and order to exact length and diameter. Use dish soap or Vaseline to help putting the new one on. Takes some effort but not impossible

I've replaced most of my exhaust hose with Vetus exhaust hose from Jamestown Distributors. Good price.

Used a combination of a utility knife, pliers, and flat screwdriver to remove the old hose. Slice hose with knife, pry with screwdriver, and cut wires with the pliers. New hose went on pretty good with dish soap.

Are your exhaust outlets above the waterline? If so this is not that hard of a job...Just not a very fun one.

Double clamp your hose connections!

First off thanks for replying with all the great information.I've had a lot of craft over the years, but this is my first inboard.So be easy on me.My exhaust outlets are above waterline, but not much. I have been contemplating plugging off the exhaust ports some how.I figured the old ones would not give in easily.They are hard as a rock and lord only knows how long they have been on their.Are some of the hose brands more pliable and easy to work with than others? Need to be speedy at my task im sure!!

Again thanks to all Great site full of folks..

Make sure you get marine grade hose rated for exhaust. Use dish or hand soap for lube. Use lots of it. You can get plumbers test plugs to block the exhaust from outside the hull. Stuff it in and tighten the wingnut and they expand to seal the pipe. You can weigh the bow down to bring the stern up. Use coolers and trash cans full of water all the way forward. Watch out for the wire in the hose. It will poke you and that hurts!

Be sure to order a slightly larger ID than the pipe calls for--like an 1/8 inch. Makes assembly (and the all important disassembly later on) much easier. And it doesn't leak, either--done it that way many times.

Yep and I thought I had the market cornered on innovative ways to get thing done.Great Ideas. I was going to use Trident corrugated hose my only worry is what clamps to use with the ribbed exterior.I measure up at 2 1/2 ID.
I don't believe they have 2 5/8.Man I would love for it to go on easy..What about warm soapy water to soften it up, but maybe the heat is a waste of time since its high temp hose?Have any of you ran without mufflers?

Thanks

Has anyone tried using an automotive exhaust pipe expander to loosen things up a bit.
