I did learn a LOT about ducting from this experience. I will now gone into the master stateroom and reconnect the ducts for better airflow. My ducts on my main unit were kinked and compromised airflow significantly.
Just in case anyone is wondering, The outlet from the 16K btu unit in the main salon has a 6 inch supply feeding a 7 inch duct and a 3 inch duct. There is a square box with 2 outlets on the original factory unit. I added a Y fitting on my new unit and then stepped one side up and the other side down. The hoses after years need reinforced and I get an enormous volume of air now flowing from both vents. The 3 inch duct is the supply on the starboard side below my cabinet and the 7 inch goes to the vent on the shelf behind the folding salon sofa bed.
IF I were you randerson I would take the duct off the side that is going to the guest stateroom and see if it is crimped or kinked leaving the unit. Especially since you said the air increases if you partially close off the flow in the master. There is an inner duct you can't feel unless you disconnect it. The insulation surrounding it made the pathway impossible to check without disconnecting. (sorry for the long ramble all)

Thank you for your valuable input. I plan on disconnecting that duct this coming week to determine if there is a kink or some type of blockage.
 
Does anyone know what rail diameter is at the bow? I would like to add a pennant staff to my 2000 400DB.

1 1/8” The bend in the front prevents mounting some staffs centered. I thought about adding another to the other side but never did.

We are cruising the Chesapeake this week and for the first time water is getting into the forward bilge under the vip bunk. It is not coming from the sump box and don’t see any plumbing leaks.

Has anyone had this happen and if so what was the fix.

Might be condensate from your AC unit under your galley stairs. Check to see if the drip pan under it is full with the drain line coming off of that clogged with dust. Your bilge under the galley floor would be wet too.

Figured it out today. The check valve on the forward emergency pump was bad. Water entered through the discharge through hull fitting past the Whale Check Valve.

Going to replace them all.
 
Has anyone replaced the lower rub rail end cap? Boat went up on the dock in a storm and came off.

Hi everyone, has anyone replaced the screen in the 2nd bedroom port light? Greg

If you mean the flyscreen I think it can be done with off the shelf screen material from hardware store. It’s been mentioned before in the forum. Also I am pretty sure Paul on BoatingWithBoogaboo at YouTube did this on his db in a video some years back. He used an oem flyscreen I think. Probably from FP. Looks like the ports are the same on sundancers from that period also

Hi everyone Just wanted to tell you. That buying aftermarket parts can cost you dearly. I have vac flush toilets so I bought aftermarket parts. It was the biggest mistake in the world. I fought vac leaks at pumps to water valves leaking . Fought to fix it for over 3 weeks. I have a 2001 400db there is not alot of room. So i would recommend the manufacturers parts It will save you a lot of grief

thanks for the warning, what parts were they . the only parts I have are spare seals from decaray and some duck bill valves from an ebay provider with a good reputation. did it all work out when you switched to better parts
 
Hi Pgeee The new parts that i bought where from Environmental Marine. All parts for toilet to vac pump. The toilet and pump are working great. 50 sec pump run and vac pressure lasted overnight. Example the junk vac pump the place were the small oring sits has bumps so the orings would not seal so water went past the oring into the bilge a real mess to clean up.

I removed mine and love the extra space. I'm storring it for if/when I decide to sell the boat, but may consider selling separately for a local pickup. Where are you located?

Hi Paul do you think you would like to sell the seat our friends just bought a 42 and would be interested. Thanks
