Official 47 Sedan Bridge Owners Group

@FootballFan Thanks for posting! Your survey fuel burn numbers are inline with two 47DB's that I've sea trialed.

Most interesting, your oil pressure differential between port and starboard is the same that I've seen on these two 47DB's. That is, there's a close to 10psi difference, with starboard being higher. Are others seeing the same? I was concerned about this, but perhaps it's normal?

I was assured by the Cummins surveyors it is normal. Result of one of the engines having the oil filter rerouted to be more accessible. Was consistent the whole time owning the boat.
 
@Keith Zibilich what's your boat run at 85% load? I seem to recall the top speed being 30-31 mph at the time I had the plotter set up in mph not knts.
OK 47 DB owners, need some info as I am going to look at one or 2 soon. I like the layout of the kitchen location, master full beam but am concerned about performance. Ive always been able to cruise at 26 or 27 knots and I can't find firm numbers with the 600 Cummins and V drive setup. I've had the QSM 11s so know Cummins. What is max RPM and speed with close to a full load, then cruise. We travel, mostly 2 of use but normally try for a 6-8 hours a day. I appreciate the help. I know there aren't many 47s out there and hope one has a few minutes to share.

Barney, I purchased Zack’s boat about two years ago and have been very pleased with the performance of the 47 DB. This boat is not a speed demon however, I cruise it 2450 RPMs (75%) which gives me about 20 knots. Those numbers take into account a fully loaded boat with approximately a 300 pound dinghy on the platform.
 
I'm about to close on a 47 DB (more on that coming soon, after I close). I'll be transporting the boat to freshwater, and would like get new magnesium sacrificial anodes ordered now. With all my boats having lived in freshwater, I haven't needed to educate myself (as much) on the different types/sizes of anodes. So, my question is - can anyone point me to the magnesium, or zinc versions of the proper size/shape, anodes that will fit the 47 DB?

I closed on my new-to-me 47DB today! I personally looked at a few of them on the market (there are not many), and I learned a ton about this particular model in my search.

I'm sure I'll be asking many questions over the next several weeks and months, and will hopefully be able to answer questions for others in the future.

Happy boating!

Congrats! Looking forward to seeing some photos.
 
Congrats on your purchase and best of luck!
 
Does anyone have instructions on how to remove the washer/dryer unit from the master bedroom? It looks like I have an A/C drain line clog somewhere behind the washer/dryer. Removing all that cabinetry appears to be a pain.
 
Keith, See attached file from Sea Ray. This may not be accurate. There is another screw between the aft storage and the bed. I needed a 12 inch philips to remove the screw. There are also more screws in that aft storage unit.

Also, are you sure it is an A/C drain line? I took my unit out and I don't think there is a drain line there? This is not the greatest picture but shows only the feed and drain lines. As you can see my feed lines leaked unto the vent line and made a mess!

Let me know if you need anything else. Unfortunately I know this process too well!

Mike

Thanks so much for the document and the picture. It looks like I have two problems - a double failure caused me some panic (like it's actually one problem with a different source).

1) My A/C pan and overflow pan are filling up with water. I turned off that A/C unit, and the pan is still filling up. Though maybe the drain lines are tied together from the port galley A/C unit and backing up into the bedroom AC unit. It does not seem to be a leak in the master A/C unit raw water feed. So... I'm trying to diagnose this issue.

The drain lines look like they go above the top of your picture and behind that cabinet wall, where the hot and cold line wrap around the back in your picture.

2) My washer/dryer is going through a full cycle and then ending with a never-ending rapid flashing "Status/Door Lock" light. The drum is then slowly filling up with water, even after I kill the power.

Two water overflowing issues seem strange, but it looks like they may be separate issues completely... As I don't see anywhere where the plumbing tie together.

Fun!
 
I was able to remove all the cabinetry. Is there a trick to getting the hoses off? The hoses are definitely preventing the washer from being able to slide out. :(
 
I was able to get the washer/dryer out last night. On mine, the hoses were not long enough to allow the unit to slide out. However, I was (somehow) able to get my arm back there to remove the hoses. I'm going to add extensions so that I can reattach the lines -- and make this job easier next time.

Now, back to my main issue of water overflowing in the AC... I does look like Sea Ray has the Salon (port) A/C, the Bridge A/C, and the Master A/C condensation lines all draining into the same line via a few t-connectors aft of the water/dryer cabinet. There's clogging deep in there, which was why it was backing up into my Master A/C drain pan. I'll blow the lines out with air and that should clear the lines.

Next up -- figure out the washer/dryer issue.

@Smokeio thanks for the drawings and the help!

I posted this in the sport yacht section and did not get an answer. I am hoping another 47 owner can chime in?

The shower head in the master aims directly at the door. We always get water on the floor after showering. I have taken apart and resealed the base and adjusted the doors so they close but no matter what, when the head is aimed at the doors we get water on the floor. In looking at these doors I don't see how they can seal as there is a gap in the center of the door and the hinge is not covered or sealed.

Do your doors leak?

I have the same challenge and I'm interested to see if anyone has a solution here. Mine seems to drip through both bottom corners of the shower door frame.

Keith, I suspect this is an issue we have to deal with. I know for my doors between the hinge and the gap in the door, I don't see how they could stop water when it hits the door directly.

I am ordering a suction cup shower head mount and will try it in different locations to keep the direct spray off the door.

From an early post here, there were questions on the speed and fuel consumption of the 47. I just had a shake down run after maintenance (cooler and exchangers cleaned) so I thought I would document the performance. This is with full water, half fuel, 3 people aboard, all our "stuff", a clean bottom, and no tender:

There's a little more speed left here as I should be able to safely bring her up to approx 2650 RPMS which is at about 83-85% load.
