The hoses for the cockpit drains on our '81 MK III were dried and cracked, so we've decided to replace them. They are probably original, and the black 1.5" ID hose, with its steel reinforcing, was very difficult to remove. (If anyone has a suggestion for an easier technique, it would be appreciated! We've only removed one, at this point.) Looking for advice on what type of hose to use as a replacement. The easiest to fit would probably be PVC bilge hose, but I'm not sure whether there are any concerns with heat being that close to the engine. The other option would be a soft-wall water exhaust hose, but it's much less pliable, and thus would, I suspect, be much more difficult to install. Anyone that has any suggestions on this process, we'd love to hear from you!
The hose from the holding tank to the deck pump-out fitting is of the same variety as the cockpit drains, also 1.5" ID. We picked up some sanitation hosing to replace that, and some 3/4" ID sanitation hose for the holding tank vent. What we're not sure about yet, or haven't decided upon, is whether we should replace the hose from the head to the holding tank. This hose, on our boat, is a red Type A fuel line hose. We do have problems with odours from the head, and not sure whether this is likely coming from the hoses. Comments/suggestions? If we do replace this line, does anybody know how long that segment is?
Speaking of measurements, this is what we've noted:
<UL>
<LI>Cockpit Drains: 14.5" x 1.5" ID
<LI>Holding Tank - Pump-out: 12.25" x 1.5" ID
<LI>Holding Tank Vent: <X-TAB> </X-TAB>18" x 3/4" ID </LI></UL>Hugh Morrin

I originally had wire-wound exhaust hose on my boat, which I replaced by hacksawing a section out of the middle of each length, then removing the pieces individually. I replaced it with the same type, as it's incredibly tough and it's heatproof. I would not use anything less than this as the boat depends on this hose to stay afloat.
Exhaust hose is very stiff, but like almost anything made of plastic or rubber, becomes more pliable if it's heated. I brought an electric kettle to the boat and poured boiling water slowly over it, then quickly slipped it on.
As to your head hose, read the article on bad smells in Black Arts.

David,
You indicated that you "replaced it with the same type" of hose. What specific type is it and where did you get it?

It was wire-wound USCG-certified exhaust hose. Can't be more specific than that. Got it from a marine supplier in Toronto. tough as nails, a bitch to put on but should be good for 20-25 years.
Ages ago, someone who was renovating a boat spoke of spec'ing and measuring all the hose on his boat and getting an incredible deal (all cut to precise size) from Defender Industries. Give it a shot.

When I replaced the hoses on my cockpit drains, they also were incredibly stiff. When doing the install, I found it easier to pull out the cockpit drain from the cockpit sole, make the hose connections, and then push the drain fitting back in (while re-bedding it) and tightening the backing nut on it.
This gives much more "wiggle room" when wrestling with the stiff hose.
