Official 280 Sundancer Thread

Seevee: That particular gauge is no longer available from Sea Ray. However, you may be able to find it through googling, ebay, or flounder pounder marine-type surplus stores, etc. There is an alternate part might still be available, though, thru Sea Ray (your local dealer). It's very similar, but the numbers on the gauge are a little different in their max values:

Part #: 1767744 GAUGE, TELE 4/1 SR5"100PSI 240F VTRIM STB PGT. Try this link for a picture: https://www.compassbbg.com/Compass/EpcContent?page=/epc/Parts/1767744.GIF

Did you try your local Sea Ray dealer? They should be able to get you this information, too.

Chris: This isn't really specific to a 280DA, nor a Sea Ray, as any boat that has an interior can have it updated. The way to do it is to remove the cushions/backrests/etc and take them to a local upholsterer and pick what colors and fabrics you want. You could do this yourself if you're comfortable sewing heavy fabrics.

Curtiss: This sounds like something a previous owner may have installed. Myself, I can't think of anything that would look like what you are describing (although a pic would help) and be in that position. Take a look behind the dash and trace the wires and see where they go. What happens when you push it?
 
What do you guys do about the hours displayed on the gauges when you get new ones? Do they transfer over somehow?

No, they don't transfer. Keep your receipts and simply record the hours when you made the change in your log book. You do have a log book, right? :smt001 Regardless, the ECM will still have an accurate reading of actual hours. The ECM is the most accurate, anyways - When a used boat comes in on trade, I never check engine hours by the gauges - I always hook up to the ECM. A gauge replacement has no impact on the ECM.

EDIT... Come to think of it... If you have Smartcraft the engine hours "might" show up as accurate on the new one. Honestly, though, I'm not positive - I don't recall from the last time I replaced one.

I'm just wondering what the next buyer will think if the hours have been messed with. Thanks

It's an easy thing to explain and an easy thing for a buyer to understand. It's not a "common" issue, but it's not rare, either. Document it and you're good to go.

you might to want to take a pic of the hour meter reading alongside of something that shows the date such as a cell phone as part of the documentation when the meter was changed.....

Good idea - certainly can't hurt. In the end, this is pretty much a non-issue, though. After all, it's not like you're trying to deceive someone and tell them the engine has lower hours on it than actual (and the ECM still has the real hours and can't be messed with). You're telling them it has more hours on it.
 
Lazy Daze,
Thank you for the response. I spoke with the last (original) owner and he did not install anything on the boat other than a garmin (on the port side). I will look behind it and follow the wires as you suggested. I'm not going to push it, it might be an ejection seat!

Be sure to have someone take a video! :smt001

If you want, post a picture. Maybe it's something that I'm just not remembering. <<< Boy, that's an awkward sounding sentence!

I think the ambient air temp sensor is in the area below the wheel, unidentified also.
 
I was out cruising in the Gulf of Sarasota this weekend and we ran from New pass up to Beercan Island and anchored there in the inlet. Boat ran great the whole way and we hung out for an hour or so with the engines off. When I went to fire up the engines the port engine turned over fine but would go to 550 rpms and then die. The strbd fired right up as always and I went back home on the one engine. I tried numerous times to start the port with no luck. I've done some reading and I'm going to pull the water filter and the inline filter at the carb and hope that does that trick. I'll check the oil pressure sensor as well. Anything else I should check while I'm down there? I put in 75 gallons of gas on Saturday which put me at 7/8's of a tank and ran most of that down to about half a tank on sat and sunday. I wouldn't think it's the gas since the strbd is running fine.
Twin 4.3's
 
Very common Change iac valve about $100 and filter($1.50) filter is called a muffler only a small piece of fiber material in throttle body facing aft in small pocket about 3" down after you remove spark arrester need needle nose plyers whole job takes 15 minutes. Same thing happened to me 3 years ago.two weeks later other one went so now carry a spare.

Just curious, was your symptoms exactly the same? IE run up to 550 and die?

I had similar but not the same. Was running fine and just quit. Restarted fine but would only operate at low RPM. Got back to home port and messed with the connections to the oil pressure indicating switch and warning to see if it were a connection. Also, cleaned the air intake, fuel filters, and I have new plugs. It then started fine, but I've never figured what cause the problem. Iac is a simple start and can be had at an auto supply RockAuto.com part no:
AC423 {#1F2Z9F715AA, 862998} for $35.

Curtiss, keep us posted.


 
Should have mentioned $100 mercruiser dealer price. One died after going thru no wake zone when throttling up then stalled and other one died after being anchored at beach for a couple hours would idle then stall then wouldn't do anything.
 
Symptoms: 1. ran great, started great. 2. turned off both engines to do some swimming for about an hour. 3. stbd started right up, Port wouldn't start. turned and might go to 500 rpm's then died. I tried accelerated neutral with no difference. I gave up and went home on the stbd engine. 4. tried a couple times on the way home, nothing. Turned over fine but wouldn't catch. Seemed like a fuel issue.

Repair: New fuel filter/separator, cleaned air intake and cleaned little foam filter. Filter was very dirty and foam filter was very dirty. I didn't see any water in the fuel filter. I did both engines. Port started right up and ran fine for a test ride. Better than that.........it ran better than ever........got out of the hole quicker and felt quicker. 3700 rpm's gets me 28 knots. I still don't have top speed I'd like but I also don't have trim UP yet. So, trim down at 4500 I'm getting 32 knots. The IAC looks brand new and that's possible as the prior owner did about 10k of work about a year or so ago.
 
dmorin,
Where does one acquire this highly technical filter that looks like a piece of bed foam?
 
Glad to hear your running again any mercury or mercruiser dealer part number 863829 list for $1.79 each I replace every year so cheap.When iac valve goes bad no idle or when starting usually stalls.
 
The replacement tachometers I'm seeing are all 3" but the parts manual shows the tachs are 5". Are they really 5". That seems big.
