thanks everyone for the ideas. i had searched thru peggy's book and
could only come up with white vinegar. i also tried some stuff sold
by a nearby pet store as a cleaner used by vets/kennels to clean up
odors - it's an enzyme product like pure ayre. and i opened up all
hatches and put a fan where the tank had been and ran that for about 3
days. it's a lot better - but the odor must have gotten into the
glass where there's no gel coat. i'll try the other products next.
consensus seems to be to put in as much rigid pipe as i can fit. i
take that to be pvc - sch40. i'm offshore most of the time so my set
up is this - one hose from bowl to holding tank; one hose tank to
y-valve; one hose from valve to pump out on deck - the other to a
manual pump overboard. i think the worst hose was the one from the
pump overboard. i think i need to fill the tank with water after i
pump it out and pump it again to make sure that hose is clean.
while i'm at it - i'm going to implement an idea from the capt who did
the survey for me - he said to put a second vent on the other side of
the hull - there's always a pressure difference to cause air flow.
any comments are welcome. and thanks again.

i have removed the permeated (and smelly!) sanitation hoses along with
the holding tank and vent hose. i have a strong lingering odor where
the hoses were. i am in the process of replacing all hoses along with
the holding tank - but i would like everything to be odor free before
i install anything. i would appreciate any ideas.
thanks - bob t

I only just discovered Pure Ayre (and btw, white vinegar prevents
mineral buildup in hoses and retards odor permeation...I've never
recommended it to eliminate odors elsewhere in the boat). Pure Ayre
apparently uses a different "breed" of enzyme than is found in other
products...'cuz I've never heard of an enzyme product that'll eliminate
diesel odors before, only organic odors. But according to the feedback
I'm getting from people who've used it, it does!

I suspect you just didn't use enough to penetrate all the way into
cushions and carpet and/or didn't get it into every "nook and cranny."

Try it again...this time, move all your cushions and anything else that
isn't nailed down out the sun to dry for a day.

I don't think so...

More likely the hose from the tank to the y-valve...'cuz waste will
always sit in it. Do you have enough space above the top of the tank
(5") to move the discharge fitting to the top of the tank (pickup tube
inside the tank? If so, there's a li'l doodad called the UniSeal that
makes it fairly easy to do.

i think i need to fill the tank with water after i
pump it out and pump it again to make sure that hose is clean.

Maybe...maybe not. It depends on how your tank is currently vented
now--length of the vent line, where it goes. You may be able to
accomplish just as much by replacing your existing venting with one that
has a larger diameter, and maybe moving the thru-hull.
