410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread**

My 1994 400EC has gas engines, 7.4s with carburetors, that I just did a repower on. I have said many times that if my boat was diesel, I would be done. :)
My EC has a great layout, inside and out. I can manage her single handed. She can take more than I can or want too (See the Northeast Flotilla thread from 2017.....4-6' seas, with an occasional 8', between Montauk and Block Island :eek:).

As for my numbers, I don't have specifics yet since the repower, but I was cruising between 3,200-3,500 rpms on the trip home last week and was getting between 20 - 22 statue mph. Made the trip from Riverhead, NY out Shinnecock Inlet into the Atlantic Ocean coming in Jones Inlet and then home (about 115 statute miles total) in about 5 hours (not counting stop for lunch in Freeport) using a little over 3/4 of my fuel tanks (300 gallons total). I will have the fuel number when I refill on Saturday.

s022mag, the decision about getting a gasser 410 or a diesel depends on what you plan to do with the boat and where you are. I have heard people who are on the larger lakes that diesel is not readily available so gas is the way to go. If you are looking to do some longer cruising, I would say diesel would be better. It comes down to your use, your plans, and justification of the price difference.

Yeah...but the diesel guys would tell you that we'll replace 4-5 big blocks before they do their first "major". :)

Someday I'll probably own a diesel powered boat, with any luck. I'll recall fondly the days of defending my merc's...and my <$500 cost to winterize!

410 express with Cummins... 26 gph @ 26 knots

For comparison - 2001 410 Sundancer w/ 3126's.

I took a few more readings today. These are estimates based on published burn and my gps speed and digital tachs. Full Fuel and water.

2200 rpm.....16.6 gph.....16.4 kts.....0.99 Nm/gal
2300 rpm.....19.1 gph.....20.6 kts.....1.07 Nm/gal
2400 rpm.....21.6 gph.....21.5 kts.....1.00 Nm/gal

Looks like the sweet spot is about 2300 rpm but seems to be similar to what others are getting, right around 1 nm/gal

4kts speed increase with 100 more rpm... Interesting. What do you use for fuel flow gauges?

Cat published burn rates...I don’t have fuel flow sensors. The 2200 rpm speed was taken another day, different conditions, but just a data point. I put them in a spread sheet, but for all practical purposes, the boat gets around 1 nm/gal +/- at cruise and seems to be consistent with other 410 Dancers.

One thing I should probably record it trim tab position, and the speed change up vs down.

Hopefully all will be well. Did you put together and install the draining system for the transmissions? Interested to here how that work out.

I just plugged it in. Sucked 2 gals of tranny fluid in about 1 minute. A new filter and fluid, I should be back up and running again in less than an hour.

Not bad considering it took me a day or two the first time with the mess I made and running for various tools rags pots etc...

Very nice! I see you went with the 90 degree valves on both transmissions and your going to leave the hoses attached. I’m going to have to get a parts list from you before I do mine in the fall.

That’s about what I get at cruising speed too.
 
Mine is 10 amps as well.
 
I had a 1997 400 DA (sold it) but have a left over power pack for the Norcold refrigerator. Does anyone know the model number of the Norcold used in the 400DA? Was going to list it on ebay. This is a long ago discontinued part for Nevercolds.
Thanks….
Edit....believe it was a DE461?

Recently brought home a 2001 SD. Everything went as planned. Once at home port, hooked up to shore power with new cords, and starboard side is not getting any 120v. Its showing on the panel, but no plugs or systems work. Any tips?
 
Led bulbs? Been reading so many posts thought I would just ask- anyone on the 400 da replaced bulbs to switch from all the halogen to led or did you have to change fixtures? Any link to what was used would be greatly appreciated. I want to start with the arch and cockpit and then all lighting in the cabin.

Could be the Norcold DE561 -- that's what we have on our 400 EXP. Let me know when you get it listed -- might be interested in picking it up as a spare.

I replaced all my lights in 2017. There's a post somewhere on here about it. I didn't have to change 1 fixture, only the bulbs. I got them all off EBay. Can't remember exact places I got them, plus some of mine were green. These are the cheap china bulbs and I figured for the price I would try them. So far I have not had one problem with them except that 2 that I put in the cabin were dimmer than all the other ones. For the Nav lights I bought better ones from Superbright on EBay. They are also the festoon bulbs but I think the Red and Green are 37mm and the stern is a 42mm. Try the links below to get you in the vicinity and pick from there. I'll try to post some pics of mine if I can find some.

Arch and Cockpit were similar to these: https://www.ebay.com/itm/20x-Super-...e0AAOSw6DtYV4eN:sc:USPSFirstClass!48239!US!-1
Cabin were similar to these:https://www.ebay.com/itm/G4-LED-Bul...562255?hash=item288277830f:g:ovkAAOSwhWpdSGJx
Engine Room was similar to these:https://www.ebay.com/itm/10x-Cool-W...WQAAOSw69tcJw-6:sc:USPSFirstClass!48239!US!-1

Not sure if this is the problem or not but I had a GFI trip in the cabinet of my aft head one time that had me baffled for awhile. Check for that.
