In response to a suggestion by a fellow 410DA owner from up in the North who said we need our own thread, I am starting THE OFFICIAL 410DA thread. This is it. Post your comments, questions and BS here when talking about our boats.

I'd rather an "unofficial" group......but that is just me! That way we can make fun of gassers......
 
I'm in.

We can include the 400DA but we ain't letting' in no 400/410EC unless they bring lobster.

Is everyone happy with the thread name change?
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

Fine, go ahead and let those Expess boats join the Sundancer thread. Are we letting gas boats in this thread too?
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

Did you get any lobster for letting does straight drive non DA boats in here?

Since I started the thread and since I have a gas boat, the answer is yes.

I guess you could go start a diesel only thread; then everyone would think you were a snob...

Just trying to bust your balls. The 410DA is a great boat even with gassers!

I know that...but some of those New Jersey boys have that diesel boat snob attitude...along with some of those Bridge Boat Guys...

Thanks, Rick.

I guess this is another thread I won't have to read or worry about, since I don't have an official 400/410...................

If Frank does not read and contribute to our 410 thread, i am buying a 450da.

With this said, my fuel gauges have become flakey. Until now, they have been perfect. 2 weeks ago my starboard was pinned to empty and my port was between full and 3/4, after filling both tanks. After running a few minutes, the starboard woke up and matched the port gauge, ut neither gauge was showing full. Today, my starboard is once again pinned below empty. If someone else had a similar problem, I was hoping they help me troubleshoot. I plan to pull the dash cover and see if there are any loose wires on the gauges. If all good, maybe I have a loose ground, but not sure where the ground would be. I assume somewhere in the ER? I may also swap out the gauges, but it seems like I am having trouble with both gauges, which make me suspect a ground issue? Unless both senders have gone bad at the same time...

All help is appreciated!

Jeff

FW is always welcome! But, certain 480DB owners are not allowed here.....he knows who......I mean.... they know who they are.

Dani-Lu:

I can't help with your Fuel Guage issue but I have had a similar issue with my port side Oil Pressure guage. I nearly had a heart attack two seasons ago when I was just getting ready to exit a local inlet in heavy traffic (Shark River Inlet between the bridges for you local guys) and the port oil pressure dropped to zero. I IMMEDIATELY shut down that motor and raised the hatch for a look-see. I was expecting to see oil everywhere but I was very relieved to see my bilge nice and clean. The admiral was at the helm (ALL NERVOUS) and I had her restart the port motor with instructions to be ready to shut her right back down. (This is for diesel powered 410DAs...nothing for you critter turd eatin' Virginny boys to see here) and I had my eyeballs focused on the motor top mounted mechanical oil pressure guage. It was like a ray of sunshine to see full pressure on the ER guage and zero on the electric dash mounted guage. I jumped back up to the helm and had a safe trip home.

Then, I had to diagnose the issue with the helm guage. Turns out it was a simple oil pressure sending unit. HOWEVER....I have yet to be able to get the two dash mounted guages to read the same. AND...every so often, only when I bump the throttles from idle, the pressure on the port side helm guage will jump to zero and back....like I turned a swithc on and off. I've swapped the sending units...bought two new ones...and that port oil pressure reading at the helm just has an issue. There must be some kind of intermittent short somewhere between the sending unit and the helm...but I haven't been able to locate or rectify.

Jeff,

You trouble shoot fuel gauges in the engine room........leave the dash alone.

Remove the center wire from the sender in the tank and temporarily short it to the tank ground. With it shorted, the dash gauge should read full....or rather the gauge should peg itself to the right, full side. If it does, the gauge is ok and the sender is the problem; if it doesn't peg itself, then the gauge is the problem. Having said that, your problem is going to be the senders. When they fail, you get flaky readings and sticking gauges that might correct temporarily with the boat bounces about in seas. The fix is going to be to replace the senders. When you get around to it, get the puck type sender, not the arm type. The only disadvantage is that you will probably have to remove a sender and measure the tank depth then order senders. Best source is most likely Florida Marine Tanks who built the tanks in your boat.


And, I sometimes don't read these official threads.......if I miss something you guys want me to see then send me a PM or something.

Well, Cap'n Frank

Thank you for your informative and educational post to our thread. We appreciate your wisdom and participation, even if you do not own one of the aforementioned vessels. Feel free to drop in at any time.

And, for the Joisey Boy, I seem to remember you eatin' a bunch of those critter turds (boiled peanuts if you didn't read the Liberty Landing thread) while washing them down with mudslides and Patron.

And if you need help locating the sending units just shoot me a message. They are fairly easy to access once you know where the access hatches are...
