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.

My port oil pressure is also at zero with the mechanical gauges showing perfect pressure. This must be a common issue. You say you replaced the sending unit? Have you checked the gauge itself? I am thinking about swapping sides on the gauges to see if the port side is bad.
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

Swapping senders is easier and will tell you the same result. The sender is about a $20 part so its not worth fretting going to extremes in diagnosing. They do occasionally fail, but it usually happens when they are new. A far more frequent problem is that the port and stbd gauges read enough differently that you want to do something about it. The engine mounted Caterpillar gauges are mechanical and are right. If you get the Teleflex sender/gauge within 5% of the mechanical one, you've done pretty good, much worse then that, order another sender or a pair of them and keep trying new ones until you get a pair that are close.
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

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.


frank.....who doesn't own a 410


Frank,

I will try what you said this weekend. I hope the sender and wires from the sender are obvious.

Thanks as always!

Jeff

Dom,

I too have a false port oil pressure reading on my dash, but the engine mounted gauge is fine. Basically when I throttle up, the dash gauge goes to 100 PSI. It settles down to 75 after running for 20 minutes. Like you I swapped out the dash gauges with no change. I assume it is the sender and I found one for $55 which I have yet to order.

For us 410da's owners, both gas and diesel, this thread is going to become a real asset. And, for us "gas respectful" Cat 3126 owners, this thread should also be an excellent place to deal with issues and positive experiences with our engines and boats!

Frank, where do you get the senders for $20?
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

Local Sea Ray dealer.............Ordinarily you wouldn't go to the dealer or to Sea Ray for something like this, but Sea Ray orders common items by the ton and their prices are ridiculously low even with the dealer and SR mark ups. We did the same t hing on a special breaker used for generator controls for a 450DA owner........cost at West Marine was $48 but we got one sent from Sea ray and billed thru my dealer in Panama City and with everyone's mark up the owner of the 450 paid $31, plus freight.

Y'all just need 450's instead of 410's............450 guys stick together.

No way! The 450 is too wide, too much cockpit room, too much space around the engines, handles too well and is much too efficient for me!

My port gauge had the same exact issue earlier this season. Although it would drop to 0 and then return to 50 intermittently. I also wasn't overly concerned because I had just had my sea trial with my diesel mechanic going through everything with a fine toothed comb. In any case it was this puck shaped sender unit that needed to be replaced. Now the gauge shows strong oil pressure consistently.

Hey....I thought the purpose of this thread (the whole forum for that matter) was to 'share' 400/410 war stories?! PM'ing is rather 'snobish'! Do we want to turn this into a 'snoby' group of Sea Ray specific model owners?......That would be like those 'snoby' 450DA owners who don't share their 'stories' with the rest of the SeaRay members here and keep everything to themselves?
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

We are three pages into this thread and we already have boat snobs...plus some 450 guy keeps poking us in the eye with a sharp stick. Next thing that will happen is picking on the gasssers.

Oh, wait, YOU already do that....
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

I like the snob thing....maybe we should have a special site for selected owners.....kind of a "boat snob" thing....Nah..that just wouldn't be right.
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

Yeah...we'll start an email listing. All 400/410 DA/EC owners should PM their email address to mistercomputerman and he'll set up a group so we can just email each other our discussion topics....like that other group of snoby Sea Ray Model Specific Owners....we won't share any info here.
 
Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread

Hi everyone - new to the site and had some questions for you guys.
Currently own a Bowrider and wife and I are looking to trade in for a 2002 410 Sundancer. We have looked over a lot of different boats, different makes and models. As soon as we stepped on this boat we fell in love with its setup and wide beam.
Any comments on this year and model, what I should be weary of in the purchase, and any other comments and suggestions.
i will obviously get a survey done before purchase, it has diesel CAT engines And has 290 hours on each engine.

Thanks

OK, sorry guys. Below is what I sent in the PM...

"No problem Jeff! Port side is easy, the door to the storage space just to the left of the cabin door has a small hatch under the carpet. I simply cut the carpet around the access hatch, removed the hatch and reached through to remove the sending unit. There are 6 screws I believe that hold the sending unit in.

The starboard side is a bit tougher. There is a small mirrored double door in the mid berth. Empty that cabinet and unscrew the access hatch and the sending unit is right there. Just put some towels or a tarp down before starting and have a plastic garbage can to drop the unit in. Make sure you check to make sure the arm is not impeded by anything before you wrap things up. You would be better off getting the type of sender that is a puck style instead of a long arm. Check with the outfit Frank recommended and they will get you the right one. Get the capacities and any other information off of your tanks. They have different capacities but should take the same unit. Your starboard tank has about 18 gallons more than the port to support the genny.

Have fun!"

Nope, I put a piece of water hose around the water pipe and put a bit of grease on it for now.
