Hey all,

Just sold my 89 230WE after 7 happy years. Looking at a 2008 240DA but it still has the portapottie. Has anyone installed either a manual pump out holding tank or vacuflush to a 240 of this era that only came with a portapottie from the factory?

Anything else specific on this model to look at? She’s in great condition with documentated maintenance.
 
I believe vacuflush was an option on an '08 - I would look for one already equipped that way - a conversion is expensive and time consuming - plenty of boats out there for sale and its a buyers market
 
I don’t necessarily need vacuflush. It’s a friends boat and I know it’s history from day 1, which is very appealing to me. Is the only factory configuration portapottie or vacuflush? I don’t really like how much room the vacuflush takes up in the engine room, as a tight engine room is why I just sold my 230WE. Any factory manual holding tank setups?
 
KISS? Upgrade the porta-potty to a 5gallon lower section (the "holding tank") instead of the standard 2.5gallon. Consider installing an "MSD" porta-potti which can be plumbed to a deck plate for pump-outs.

I have heard the 5gal potty with pump out (what I’ve had on my 230 for the last 7 years) fills up about as fast as a vacuflush of double the size. That (and cost) is why I was wondering about a manual head with larger holding tank. Big fan of the KISS method though.
 
I had a Bayliner 2355 with a manual flush head. It had a 13 gallon holding tank in the bilge, starboard, with a 13 gallon water tank stacked on top. Everything else, batteries, water heater, etc, was on the port side. I don't know what sort of space you have back there but a 13 gallon tank with careful flushing was more than adequate for two people to go 3 days

I recently had a new system put in my 270. A manual flush head, a 24 gallon tank, plus new hoses ran me about 900 bucks installed. I already had a pump out fitting and seacock in the boat.

that’s great info. Yea under a BOAT dollar for a manual system would be great. Already has pump out fitting but boat is from a protected lake where no holding tanks are allowed. Gotta be sure there is room in the bilge though.
 
If you have a pump out fitting, I wouldnt be surprised to see an unused seacock for flushing in there somewhere. That would make your job pretty simple, assuming you find space
 
Ok well the 240 came home with us. I’m going to hook up MSD kit to current 5gal portapottie. Question is, boat seems plumbed but only waste (not vent) goes into head. How do you gain access behind the holes where head lines enter? Seems as though it’s through the mid cabin, assume that panel comes off inside?

pics for thanks!
