    OFFICIAL 390/40 Motor Yacht Thread

    If you replace it, make sure to get a vented model like one recommended by Mike V above. Ventless ones do not dry very well. Some people do not like these washer/dryers because they are so small and the dryer tends to wrinkle clothes. When we did the Great Loop, we used our very often. Was...

    OFFICIAL 390/40 Motor Yacht Thread

    Lake Michigan is definitely one of the highlights of the loop. We went down the east side and there are really nice towns and harbors every 40 miles or so. We replaced all 4 Group 31 House/Start batteries before the trip. As mentioned we have all LED lights which makes a big difference. Also...

    OFFICIAL 390/40 Motor Yacht Thread

    We have a 2005 399MY with original battery setup. I have thought about adding more capacity to the bank that powers the refrigerators, but as you mention there is not a lot of unused space in the engine room. We did the Great Loop in 2022/2023 and would run the generator in the morning and at...

    Sea Ray 390 Motor Yacht replace windshield rubber seal recommendation

    Order directly from Taylor. Also, these seals tend to shrink over time, so when you put new ones in best to cut as them as long as you can. Mike

    OFFICIAL 390/40 Motor Yacht Thread

    There are no shaft zincs on our 2005 390 Motor Yacht. Was this way when I bought the boat 5 years ago and I never added any. Does not appear to be any corrosion on shafts or props so seems to be OK. I am curious to find out if other owners have shaft zincs on their 390/40 Motor Yachts...

    Any non-Yacht options that can sleep 6 adults?

    You can sleep 6 adults on a Sea Ray 390 Motor Yacht. However one bunk would be the pull out sofa in the Salon. Boat also has two heads which you will want for 6 adults. The 390 motor yacht has a lot of usable space for its size.

    looking at 390/40 MY

    I just finished the Great Loop in a 2005 390 MY with 480CE cummins engines. It is a great boat in my opinion. For 480CE engines think you want to verify upgraded heads were installed. On my boat prior owner had them replaced. Not going to be covered by warranty on boat of this age, so Cummins...

    Think our stove cook top is 220 volts. Does your inverter provide 220 volts?

    Pretty sure head will have a part number on it, not sure where though. If you ask question on Seaboard website someone will know. Or ask Cummins. In my case engine surveyor was cummins dealer that had replaced the heads, so finding status was easy.

    This is another Mike. Suggest you look at www.sbmar.com/ if you have not already. Lots of information on the 480CE on this web site. From above site: "The first new Serial number of the revised heads was 4664956. Anything prior to that has the old style valve seats which are know to fail...

    Location of ECM fuse/breaker for Cummins 480CE engines on 390 Motor Yacht

    Cummins manual indicates that there should be two power wires for each ECM on 480CE engines. Each wire is to have a 10 amp fuse/breaker. Have looked and I can not find these two fuses/breakers anywhere. Also checked the Owner's manual and I can not find any mention of where fuses/breakers...
