  • Bilge exhaust questions

    There's a piece of PVC pipe [as shown below - the hose next to the pipe is my new hose] in between a rear and forward section of blower vent in my PS 205. It was mounted to the engine exhaust with zip ties. Is this special marine pvc that serves a purpose or did the PO use it to avoid fishing a vent behind the gas tank when replacing the front section of hose?

    Also, I have two vents at the rear of the boat but only one is attached to the blower. The other hose ends behind the gas tank. Where is it supposed to go? Should I have two blowers installed?

    Idk what the pvc is for but the 2 stern vents, 1 is hooked to the blower, other is fresh air into the bilge.

      Thanks for the confirmation on the pvc. So is it good enough to just have the fresh air vent run down behind the fuel tank or should it get up near the engine?

        Good to know I was wondering the same about the second air vent in the rear. I have a pvc pipe too. It was attached with a zip tie also so we just reattached a vent tube to the blower and the pvc back out to the vent in the rear and zip tied it again.

          Where there zip ties on the hose with the PVC? I believe it's like that so it could be zipped tied to the muffler without crushing it.

            That's what I'm going with. I can imagine a scenario where a few inches of water could collect in the bilge causing an untethered bilge vent hose to start floating around, which could then get tangled up in the drive shaft or the rudder.

            It's sort of like wearing a jock strap, not necessary most of the time, but sometimes it's nice to keep the boys close to home.

              My 92 had the pvc pipe in it and was zipped tied to the muffler. Never knew if that was factory but it made good sense to me at the time so left it that way.
