Any 480 MY owners that can give me thoughts on this boat, both positive and negative? I have owned a 390 MY in the past, but this boat looks to be more than a larger version of the 390. Rob

All Been out of Sea Rays for a few years and looking at venturing back in the fold. I am currently interested in a 2005 480 MY. From what I understand, the Cummins engines in this boat have problems with the exhaust overheating as they are "dry exhaust". Can more knowledgeable folks here...

Has anyone tied in a new display to an existing Raymarine network via the NMEA 0180 or Seatalk? I just installed a new Simrad multifunction display for my primary GPS/chartplotter to replace the old Raymarine unit that was tied to the Raymarine radar and VHF. The new unit has the ability to...

All I am in the process of adding a dedicated gen battery on my 390MY. I contacted Sea Ray about a wiring schematic for a 3 bank system to confirm my setup and I was surprised to see that the charger circuits were shown running directly to their respective battery banks with no breaker or fuse...

Guys, just replaced the Clarion 400 watt amp with a Fusion 500 watt amp and running as 3 channels as the original was run, but now it seems I have hardly any power to the sub on the bridged channel compared to the Clarion. What gives?? I increased my power by 100 watts!! I also replaced the 4...

Does anyone know what the direct replacement breakers are that goes in a 2004 390 MY panel in the engine room? I need to add a circuit and want to use one of the open slots. Rob

Everyone, I currently have a 2004 390 MY that has the original Raymarine electronics including the VHF, Open Array Color Radar, and the old style GPS without chartplotter. The GPS has a depleted internal battery, I am told, and it loses its fix continuously and sets off the annoying alarms on...

Guys, I am looking at replacing the old Raymarine GPS that came standard on the 390 MY next year and am wondering if I should stick with Raymarine or change over to Simrad, Garmin, or another option. I still have the old open array Raymarine radar that works fine, but I assume it is not...

Does anyone have an elevation motor gear box from an acr 100 spotlight? You have to buy the entire motor and gearbox from Acr at nearly 300 dollars. My motor is fine, but the gear box apparently had water intrusion and was totally froze up. I would be Willing to pay for the gear box alone if...

Everyone I have read hundreds of threads looking for someone that has done what I am wanting to do, to no avail. I have a 2004 390 MY which is set up with two series 31 batteries on the port and starboard side to serve as house and starting batteries for both engines and generator. There is no...

Guys, I have a 390 motor yacht that carries 100 gallons of water. I had three quarters of a tank when I left my dock, traveled 20 miles, and my tank is empty! There is no sign of water in the bilge! Help!!! I am baffled as to where 75 gallons of water could have gone!!! Rob Sent from my...

Does anyone know where you can purchase the lower shelf, part number 523003600, for a Norcold cockpit refrigerator? It is for a 2004 390 MY. Thank you, Rob

Guys Just bought a 2004 390 Sea Ray MY with the SC 5000. The instrument and display are fine, but the joy stick selector is worn out in two directions. Does anyone have one that is scrapped that could remove the joystick. Be willing to pay a reasonable price. Rob

I just purchased a 2004 390 MY with the Mercruiser Smartcraft monitor which is great, but the toggle button is worn out in two directions. Does anyone know if the toggle switch/joy stick can be replaced without buying a new unit? The unit works fine, but I can only toggle in one direction to...

Okay, we all talked about it, so I am going to start it! I will be closing on and taking delivery of my "new" 390 MY next week. Immediately upon delivery I will be taking it on a "shake down" journey over 200 miles to home. I plan on getting a Go Pro and documenting this journey up the Ohio...

Curious if there are any 390 Motor Yacht owners on the forum and if I could get some thoughts on this boat. I have my 340 DA for sale with hopes to move up, and the 390 is on my short list. Any feedback would be appreciated. Looking specifically for handling characteristics. Rob

Everyone I have a complete set of canvas in the almond toast color including isinglass with zipper openings in front panels. Also have front sunshade. This set is serviceable but in need of minor zipper repairs and only one small area near the seam in the front panel that needs repair. This...

Gentlemen Yes, I use that term loosely....lol. I do have a question for all those much more savvy than me. As all of you know that have a 340, the engine compartment sucks! What can you actually remove on the exhaust system without sinking the boat?? To even change impellers, you cannot...

I have a complete set of canvas (toast color) for a 2002 340 Sundancer. (Shown in place on picture below) The canvas, I believe, is original to the boat, but I also believe the clear panels have been replaced at some point as they are clear with no clouding and in new condition. (I purchased...

I have a 340 Sundancer with the Lofrans Windlass. The windlass will deploy the anchor and rode without issue, but fails to retrieve the anchor and rode as soon as any resistance is met. The drum spins without pulling. I have also had issues with the windlass failing to feed the rode into the...
