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

I think it’s finally time to replace my fresh water pump which, as you can tell from the date stamped on it in the attached photo, is the original pump. Perhaps this is a silly question but how do I disconnect the wires? As you can also see in the picture, the connection has a hard plastic sheath around it and I don’t see how to disconnect. Do the wires need to be cut and spliced together again?

Also, for those who have replaced their pumps, do you have any recommendations on manufacturer, GPM, etc.?

Any advice is greatly appreciated.

This is what I ordered. I'll let you know how it goes when I install over the next couple days.

The install bolt pattern doesn't match what was installed on my boat, but I don't think my pump was the original because the original is listed as 3 gpm, and what was on my boat was 4. As long as you can fit back there, which I can't, the rest of the install is straightforward.

The really fun part of the process was spending 6 hours installing and troubleshooting only to find out that Skipper Buds had drilled through my supply line when they were doing some transom work over the winter, which was the source of the whole problem.
 
This post is to say nothing more than how much we love this boat. We’ve spent a bunch of days on the water this week with the family, dinghy up to the beach, cruising around, etc. Bigger is probably better, newer too, but I think the 410 is damn near perfect (especially for where we boat)

My port side step keeps flopping down. The one that hides the fuel valves. Has anyone rebuilt theirs or have a diagram of it?
 
I rebuilt the deck access step on my 450DA. Not hard after you figure out how Sea Ray mounted the danged thing. We are in salt water so most of the time invested on my boat's step was sand blasting and acid dipping the aluminum step frame, then epoxy primin, and final painting with Imron. I also rebuilt the hinge from new aluminum stock and stainless fasteners. The fasteners (nuts) holding mine in the side wall could only be accessed from the back side which left me looking like I lost a fight with a barbed wire fence.

It was a pretty easy job once you get the parts on a bench in front of you.

Does anyone have the part# for the water bib/pressure regulator inlet located in the stern locker next to the shore power terminal? My water pressure is great with the pump but terrible when hooked up to city water at the marina.

I used this one, you need to enlarge the hole slightly though. They also make a 60psi version which our fittings are supposed to be able to take but I’m happy with 45 and didn’t want to push my luck for a leak on 20 year old plastic plumbing

I replaced mine a couple of years ago. I used something like this: https://www.defender.com/product3.j...3-029-14)&path=-1|51|2234261|2234266&id=10361
Edit, I think I bought a 45psi, what I linked to is 65.

Also, something that REALLY makes life easier - I purchased a 10' length of drinking water hose, and I connect that to the hose that goes to the city water on the dock. When I take the boat out, I disconnect the 10' length from the city water supply hose, leave the supply hose on the dock, tuck the 10' length in the trunk but don't disconnect the 10' length from the boat fitting. It eliminates all of the screwing and unscrewing from that fitting in the trunk. I don't know if this is the exact model, but it is a drinking water hose, soft and flexible, and makes the whole process much easier. https://www.amazon.com/Camco-Diamet...=10+ft+camco+water+hose&qid=1657559424&sr=8-7

I do something similar. We use quick disconnects so I disconnect the two power cords and hose at the same time and coil them up

Same as well. I've been doing this for 4 seasons or so with both power and water. Absolute game changer for quick departure/arrivals.

I'm with you 100% Strecker25. We're just back from a 10 day 250 mile trip with a family of 4, carrying a dinghy, and electric scooters for everyone onboard. She's big enough to accommodate all of us, all our supplies yet not so big that I ever have trouble with a marina accommodating us. Even ran home in bigger water than I would typically head out in, but she handled it without skipping a beat or making anyone uncomfortable. I've been running her for 4 years now and couldn't be happier. Sure I'd love a newer 47 Sundancer to eliminate the isinglass and have cockpit a/c, but I don't think at 3 to 4x the price we'd have any better of an experience. I'm working 4 days this week before heading back out for a long weekend travelling again and the end of today can't come soon enough!

It's great hearing you are still good with a family of 4. If you don't mind me asking, what ages? My kids are still really small - 4 and 3 weeks old - so we have no sense of how it will all work out yet. When they're a bit older I could see my son using the bunk (until he's too big to fit) and then later one of them on the couch.
 
Thank you
I am tired of mine flopping down too. The springs need to be replaced. In the meantime I am adding a couple male screw in male snaps and about an inch long piece of webbing with female snaps to hold it closed like the companionway door.

Congratulations on the newest addition to the family! I love hearing someone else starting them off young! We started trips with our kids at 3 and 1 on a 300 Sundancer. That had a bench at the helm and we'd put our son in a travel booster seat next to me and away we went. At 9 and 7 it was getting to tight in there for my wife's sanity though and we started searching for our 410. My daughter is now 14 and claims the aft while my son is 12 and has moved from that bunk over his sister to the salon sofa a couple years ago. I do miss when they were both in the aft and I could make coffee and sneak to the cockpit in the morning undetected. They now both have their boater safety completed and run the dinghy around at home as well as exploring our different ports of call. They are both a big help around the boat in and out of slips as well as with maintenance tasks. It's to the point now where I can run the boat with just myself and either one of the kids. It's great if my wife is out of town or working late; the three of us can head out whenever the mood strikes. Or as simple as last night running to fuel up and pump out on a non-weekend day. I can't think of a better way to raise kids than boating. They learn plenty of rules, respect, and responsibility and have a ton of fun in the process.

I'm in my 4th season of running 3 kids with the setup below in the midcabin of my 400. Currently they are at 12, 10 and 7 and still all loving it. I've even had a full sized dog sleep with them on the floor a time or two.

The top bunk will fit a full size human with plenty of room to spare. I think I have another season until one or both of my younger kids will be too tall to sleep in this orientation on the cushion/bed portion. Ideally when that happens I'll have them rotate 90 and sleep head to toe. If they can't tolerate that level of closeness I'll have to start using the couch. Either way, plenty of room for 3 back there...for now.

ah I didn't even think about how short they are :)

Having them sleep that way is perfect.

It really is ideal. We put the cushion from the cockpit that goes over the step (starboard side) in between them and they're quite separated. They setup all their stuff and create a bit of a wall between them

My daughter is 52" tall now...I think...and she is still good to go on the starboard side as pictured. The port side of the midcabin is a bit shorter...sadly.
