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.....
You know - thinking about it - that secondary drain could simply dump in the engine room bilge and be done with the risk. If it is ever needed who cares where it dumps as long as not the carpet......
 
From everything I can determine these are all the connections to that Port Common Drain Line.

I have a SeaRecovery Aquamatic. It has an automatic weekly self flush, and the regular maintenance is changing out filters. Initially we had a lot of issues with it, which were largely attributed to the yard that installed it. SeaRecovery sent a tech out, and since then it's been good.

Placement of the filters and components is critical.
 
Bow Thruster Battery Relocation?
My bow thruster batteries (located in front of the port engine) are over 4 years old and I'm starting to consider replacement. I'll go with AGM's. I'm considering relocating them from the engine room to between the washer/dryer and vacuum cleaner on the other side of the engine room bulkhead which is about the same distance to the solenoid and charger that are mounted next to the washer/dryer. This would open up better access in front of the port engine and get the batteries away from the engine room heat....
Thoughts?

Here is my 02 cents. Seems like a lot of work for a little bit of access. my batteries are in front of the starboard engine but I assume the same would apply if they are in front of the port engine like yours are. When I am working on the outside of the starboard engine I put a couple old throwable cushions down on top of the batteries and work on top of those no problem. It would be nicer to have them out of the way for sure but if your boat is set up like mine in the space near the washer there is not a ton of extra room between the washer and vacuum so fitting the batteries in is going to be tight. Also, it is right below the water manifold. If you have to deal with a leak or something of that nature now you have the batteries right there to worry about. As for the heat, I am not sure if it affects AGMs or not so I would defer to a battery specialist on that one.

I do like the idea of opening up space in front of the Port Engine. I assume you are well balanced now with weight Port and starboard sides? I do like the space between the W/D Combo for storage and access to that bilge that always seems to collect water randomly.

Agree, I'm thinking on the other side of the W/D right here between the Beam and W/D. I would probably have to move the vac a bit; but not much.

I think the weight being so close to the keel that it would not affect.

Understand - On the port side engine the raw water pump is almost inaccessible and with the batteries there nearly impossible. For me they are always a problem getting in that area. Heat is always a factor on battery life but I'm sure I could get 5 years even where they are... That area between the W/D and Beam Vac is always unused except for the random cleaning materials....

All good points. It does make a difference port to starboard because on starboard side the engine in the front there are really just the zincs to worry about for general maintenance so not as much access is needed. Agreed that getting to the port water is a tough job and warrants as much room to work as possible.

Question, Any plans to install an inverter in the future? My inverter batteries are also used for the bow thruster so you may not want to go thru the trouble making this change. Also not a big issue but weight distribution? I know my boat lists to starboard a little and I’ve noticed others do as well. Just my 2 cents as well.

Yes, extensive plans to install a pair of inverters operating in split phase. I still think we will be balanced but can move the water maker to the other side if it's a problem. The plan was to get the inverter additions done this spring but a lightning strike has deferred that to next year. These plans are under review for compliance to ABYC and hope to get it all finalized in another couple of months.... The batteries, all ten of them, will be located behind the solon sofa. The ten batteries will be about the same weight as the two 8D's on the same port side. The goal is to operate the HVAC systems over night without the generator running.
These are the plans -

I now remember you posting this.... and my only thought was... I don’t see a “Flux Capacitor”!!! Ha!

Love the idea of being able to run the AC with the inverter. We are in the Exumas now and although I can run all the 120 volt items for about 14-17 hours, it’s just to hot to go any length of time without AC, hence we need to run the genny. Inverter does however help offset electric cost when we are at a dock where they charge by the KW. I just use dock power for 240V items.

I wish I was there!
 
I just purchased a 21' aluminum Hewescraft fishing boat, which I will tow behind my SeaRay. Wondering if anyone has any advice on towing it, bridle setups, pulling in and out of marinas.
