500/520 DB official thread

Some of your bilge water may be coming from your salon ac tray. All the larger Sea Rays with common drains seem to not have enough drop from the tray's drain to the common drain system. I've had to use a small drain snake to clean my tray drains out and I've found that helped mine. When I would go up on plane, my aft tray would usually slosh out and end up in the bilge. The small snake from "China" Freight solved my problem...

My dockmate's former 52 would even leak onto his carpet by the sliding door...

Wanted to thank whomever posted about the windlass breaker location! You saved my afternoon.

Our windlass breaker tripped for the first time in 6 seasons when picking up anchor in the wind. The breeze caught the bow, causing it to swing quickly which put a strain on the windlass.

Thank God I remembered the post regarding the location of the breaker in the engine room. I was able to describe where it was was while at the helm to my wife found it. She reset it. and all was good at that point.

I Am still shaking my head thinking about how poorly located that breaker and the bow thruster fuses are. I am ordering spare thruster fuses to place right next to where they located just in case we need them.

Carter - the condensate trays for all of the AC units except for the bridge in the 52DB drain into the sump then are pumped to the common drain on the boat's starboard side. Additionally, the solon AC unit is set into a bit of a depression in the fiberglass floor behind the sofa and there is a drain in that depression. So, first the condensate pan would have to be overflowing then the drain in that secondary area plugged in order to wet any carpet....
Here you can see not only the pan drain but also the one in the depressed area:

Another issue popped up... One Battery is completely flat (Both new in April). Have been on the boat all week and all was well. Reading ZERO Volts on the Starboard Battery 8D. I assume the charger is failed or failing although the Charger indicator lights or indicating Charge. The charger DC amperage gauge is at zero.

Question - Which Charger is everyone using and liking?

My dockmate has traded up to a 58, so I didn't have his to look at. The two salon units iin the 58 drain straight into the stbd common drain. Sorry that I was off base there...

And I'm wrong again - just got a call from BMAC - his saloon unit drain clogged this weekend. While the drain lines run aft (to the vicinity of the stbd common drain), they then turn fwd and run over the fuel tank to the shower sump in the fwd ER bulkhead.

Thanks for the info Brian!
Shows you what I know!

The Charger has two internal 30 amp Fuses. The instructions state they will only trip if the wiring is reversed. That didn't happen so not sure.

I replaced both fuses and they held for a minute or so and blew again.

Update - I replaced the Starboard Battery and the Charger seems to be charging fine and the fuses are holding. Will see how it goes. Not sure what tripped the fuses yesterday... Maybe that 8D Battery did fail in some way and caused the charger to trip the fuses and that battery went flat. Not necessarily in that order...

Typically when a battery goes to 0 volts there is a direct short within it and that will trip the charger/converter circuit breakers. If another battery is in parallel it usually takes out that battery also or permanently damages it. Batteries that start to become very low in resistance will also tend to get hot and boil when being charged and make a mess if SLA.....
Extreme cases will build up hydrogen gas then an internal spark occurs and it scatters the battery all over the engine room - a really big mess....

Thank you. Never knew there was a secondary drain.

I need to check to see if we have that secondary drain behind the salon AC drip pan. Our Salon AC pan clogged and overflowed this weekend for the first time. Of course the carpet in front of the sliding door got wet. Access to the salon AC is a PIA! Had to blow out the line from the engine room which was also not fun with the engine room still hot.

Where does the salon ac drip pan drain into? The common drain and over the side or into the shower sump box?

Question, Hydraulic swim platform platform extendable ladder...

Has anyone replaced theirs? Ours had one of the bolts break off. No problem will fix it this week however the wife is asking for Nicer, easier to close ladder...

Our friends have a 48DA with a under the platform extendable ladder and it is much nicer than ours. Seems more robust, larger step pads, etc. maybe there is more room for the under the platform ladders compared to our set up under the door on top of the platform.

Trying to revive the ladder, picked up new stainless steel bolts. Wife and I cleaned and polished. Pretty happy with the results. Hope to re-install tomorrow.

Also went to the manufacturer website; GG Schmitt and Son’s. Worth a look for standard and custom stainless fabrication. https://www.ggschmitt.com/

Gary, this must be the week for condensate line pluggage. I had a wet salon carpet on the 4th from my aft salon ac drain pan overflowing. IIRC your ac pans all drain to your shower sump, just as they do on the 58. Say hello to Gina, I hear she saved your butt when your windlass breaker tripped.

You are correct Brian! I also learned today that both the salon AC and side stateroom AC unit (behind the dinette couch) are T connected to a common drain line that goes up to the sump box. In my opinion it’s nuts to do it that way. The drain line had a clog somewhere but luckily our friend Rob went above and beyond clearing the line.
Yes, Gina saved the day by resetting the windlass breaker however if she would learn how to maneuver the boat I would have done it.

A tee in a drain line is generally not a good idea. I thought I had my line cleared twice this weekend when it wasn't. What I did to really clean it out was to connect a hose at both ends of the drain line using a 1/2" nipple and one section of hose with a garden hose connector. I then ran the interior hose out the salon door and fed the hose disconnected from the shower sump with city water under pressure. This had the effect of backwashing the condensate drain line. I was shocked at the amount of material that came out. Even though my forward salon drain was draining I did the same to it. Again, a shocking amount of brown material came out. I'll do the other three as time permits.
 
Pour some Noflex digester in the Drain pans of the AC units and that will help clean up some of the sludge in the lines as it drains down through them.

Tom,
The only problem with this (at least on my boat) is Sea Ray “T’d the condensate drain and the overflow drain right under the AC unit in the bilge and then the line runs another 20’ at least to get the sump.... So if the line clogs along that 20’ length, the overflow is useless and as Carter mentioned, the depressed area fills with water and gets the carpet wet as I have experienced.... Best solution is to separate the 2 lines and let the overflow drain into the bilge at an area you can monitor.....
