    OFFICIAL 390/40 Motor Yacht Thread

    The fridge opening isn’t the only consideration on this boat. Ensure whatever you buy fits through the cabin door! It’s not square and rather narrow.

    Aluminum rail treatment?

    With the amount of spray you're going to see on the platform, I'd think 316 Stainless would be a better choice. Also from a strength point of view, I'd think aluminum might be a little light.

    Searay 390/40 or Cruisers Yacht 405/415?

    4K puts a 6ft platform from Swimplatforms.com on the back. They look and fit great.

    390MY davit system

    The water tank is in the transom, though it can be pulled for this sort of work. You'd have to remove the aft berth, night table and rear state room wall. The vertical part of the transom is accessible from the locker, aft berth and head. I've seen lifts installed both under the existing...

    Boarding ladder search

    Sea Ray 390 MY Handling

    There aren't many PWC's that weight less than 750 these days. Im sure a Seadoo Spark would be OK, but nothing heavier.

    Official Cummins 6cta 450C thread

    FYI, you're a little over propped. The fuel curve for the 450c has it at 13.6 GPH @ 2200.

    Cleaning bolsters

    I would avoid a Magic Eraser, they are abrasive and remove material to clean. Many have success with Spray 9, others say try a diluted bleach soaked cloth (AVOID THE STITCHING).

    1990 420 with 3208 diesels EXHAUST QUESTION

    Try adding wolverine oil pan heaters and/or CAT block heaters. They are less smokey when preheated.

    On mine that's a platform (plywood, suspended between the stringers). It sits on top of the black water tank.

    OFFICIAL 390/40 Motor Yacht Thread

    I can't think of a void in the front of the engine room? Unless he's talking about the voids under the genset and vacufluah I'm stumped! I verified this weekend that there's no trapped water in the front void but am still glad the hull and stringers are uncored, solid fibreglass on these boats!

    OFFICIAL 390/40 Motor Yacht Thread

    Yeah, On mine water actually ran down the rear and INTO the scuppers. I pulled the aft seats and sealed the scuppers. The rear door is well enough protected that we don't get water coming in there. The wing doors can lead to wet carpet too if you get a driving rain, so we pull the carpet...

    OFFICIAL 390/40 Motor Yacht Thread

    I assumed that void was foam filled. Can anyone confirm what's actually in there? I'd always assumed the stern high attitude of the boat was down to the heavy 480CE's midship, which sit further forward than the lighter the 8.1s.

    two antennas

    Could be Am/FM. Take them off the angle, strait up and down performs best!

    Coat 1 is on.....

    Looks great, wish we could get ours home. A word of caution. Cinderblocks aren't great support material. Boat yards will only use solid wood. I doubt you'll see an issue with it but I'd track down some wood blocks for the future.

    Thinking about moving up/Cruisers yachts

    The one area Cruisers loses is ride quality. They are beamy boats without a ton of dead rise. That said, the extra beam does make for more space...as always a trade off.

    Turbo life for Cummins 6CTA

    Check out Tony's photos here. http://www.sbmar.com/articles/what-a-marine-diesel-turbo-should-look-like-when-inspected/ So long as the turbos are protected from water, they'll run a long, long time.

    Turbo life for Cummins 6CTA

    Tony Athens at Sea Board Marine has many examples in the 20,000 hour range without a rebuild, I'd say save your money. The bigger concern around the turbo is water reversion. You could inspect the exhaust output side to ensure you have no rust/corrosion. I believe this exhaust design is OK in...
