This will be a winter project for me. For those that did this, did you put a trap inline or loop the hose?

I formed a "trap" with the drain hose. Easy and it works great. I was a little concerned about my neighbors floating condo that is on my starboard side. It rarely moves except to pump out and he starts and runs it for about 15 minutes once / week. It's gas, pre-fuel injection and can get a little stinky/smokey when warming up.
The galley sink going overboard definitely helps with the shower sump box but I still clean it about twice per season. No more cooking grease or food particles, but the showers and head sinks still leave a scum line. Use of Noflex or CP helps.

What size hose did you use? What size through hull?

1 1/2" I think. Whatever the tail piece on the sink drain is. It's been a few years.

Man, I'm so tired of cleaning the shower sump. I need to run my galley drain overboard but has anyone found any way of alleviating so much of the gunk build up in the shower sump?

One of the best things that we ever did. It's going in the water one way or another anyhow. Not going to lie....there is some pucker factor drilling that hole. Measure 14 times, drill a very small hole, check for clearance, and go for it. Mine is a 98, so I had a cored hull to contend with.

Did you loop the hose for a trap?

Why a looped trap? I installed a straight run on mine and nothing travels uphill that distance into the boat.

I would rather not give the creepy crawlers or the spiders free access to my cabin, or any strange fumes.

I'm looking to put a jet ski on my 400DB swim platform. Anyone know the platform weight capacity and/or put a jet ski on?

I have the TNT hydraulic platform which I believe is about 500lb to 600lb. I've been given conflicting numbers from various sources. I put a 500lb jet ski on it without issue (SeaDoo Spark 3up). I chose that ski for the weight. The TNT platform is pretty large so I would expect a shorter one would provide at least that range, however it is fairly well braced to the transom. I'd like to see how your platform is supported before loading it up. I will note that you definitely feel the weight back there getting on plane and with the cruise attitude.

The previous owner completed a mod to directly drain the galley sink overboard. Works perfectly. No check valve either. The result is that I clean the sump at the end of the season, possibly 1/2 way thru if I think of it, and the sump stays 'reasonable'.

I did it last year and it has been great. No odor and no grease gunk.

I used a router bit on my drill to clean out the coring. Go in about 1/4 inch into the wood and fill it with a thick epoxy to seal the wood and let dry. Then caulk your fitting and tighten.

That’s what I was thinking, and if for some reason it didn’t work out, I could just cut a few inches off the hose and reconnect it for a straight shot. It works fine. Here’s what I did.

As far as the thru hull location, I just put it the same height above the waterline as the other thru hulls so that they pretty much line up. (not as low as the a/c discharges.)

It’s easiest with their impeller puller tool here. To put in the new impeller some zip tie the blades to a smaller diameter than the pump housing, then cut off the zip tie once it’s part way in. I’ve always been able to insert it just by compressing the blades together with my hand.

Any tips or experience on replacing the starboard Raw water impeller on 400 DB with Cummins?

Thank You

 

[Rudy "At Last"]

How are you accessing the Port side Raw water pump for impeller replacement?

How are you accessing the Port side Raw water pump for impeller replacement?

Remove the air pipe between the after cooler and the engine. Push the throttle lever all the way forward with your hand. Lay on top of the engine and reach through that opening with your right hand. You should have enough reach to remove the cover plate and the impeller with that one hand. At least I do it that way. Be patient and don’t forget to pull the throttle lever back before you start the engine.

Thank you. great info.

Tip of the Day: if you need to work on the fresh water pumps, take out the generator battery and battery box first. It takes 10 minutes and it makes access SO much easier. My arms were 2” too short to reach the the outer pump intake connection without doing this. I could get it off, but I couldn’t thread the intake back on the strainer. Removing the gen battery allowed even a broad fella like me to get far enough in there to easily reassemble (and, next time, disassemble). Live and learn...

What’s a battery box? I don’t have those panels framed around the batteries. A previous owner removed them. Never knew there was such a thing until I went on a friends boat. Not sure what they are for. They just seem like they would get in the way. Is that what you mean by battery box?

Yep. That framing around the batteries. I guess they keep you from bumping the battery. Also, they give you something to lay across instead of the terminals! Ha ha. But even without the panels, taking the battery out is a big help.
