    Pros and cons of the 2006-2008 version of this model?

    I'm surprised the Powerboat Guide and other specs I've found says the boat is 58'0 or maybe 58'8" AOL... and maybe or maybe not including the big hydraulic platform attached aft of the molded-in platform... whereas USCG records show these being documented at 54-55'.

    Ditto surprise at published 16' beam specs versus documentation at around 15½'.

    ??

    Pros and cons of the MAN V8-900CRM diesels? (I think these are also labeled D2848LE423?)

    I suspect the earlier 800-hp version D2848LE403 in the earlier 550 model (same boat) were mechanical engines, so the "Common Rail Marine" version would be an updated electronic version of that block?

    Model Specs LOA should not include add-ons such as swim platforms and bow pulpits. Individual boat specs will. That's your 3'-4'. The beam # sounds like rounding up.

    Yep, I thought most "LOAs" have gravitated toward only including swim platforms if they're integral to the hull.

    PBG doesn't usually round either direction, near as I can tell... although that doesn't suggest to me they're always correct. (PBG says 58'7" Length w/Platform and another on-line source says 58'8".) I'd suspect they're using specs supplied to them by the builders, though...

    The 58 Sedan Bridge was length over all.
    That included the swim platform and bow pulpit. Also the trim or rub rail around them.
    If the wind was blowing from astern, the bow pennant/burgee was measured also.
    We used to manage one.
    Our 58 Bert was measured by the old rule, stem to stern.
    Both boats side by side helped us figure that the useful length of the SD was from the sliding back saloon door forward to the crash bulkhead.
    Roughly 35 feet.
    Ad another 10' for the back deck, then you have a 45' cockpit cruiser.

    Many on YF luv this boat. I was not a fan.

    The V8-900 CRM was a beast.
    Expensive filters and oil.
    I fell in luv with them the hard way.
    At the time, no one around to work on them.
    Something you need to consider; who will work on them? A real good honest shop? where?

    The performance and quietness of them will pay off vs the much higher cost of maintenance.
    Pending if they were well maintained before including the Heat Exchanger re-work and maintenance.
    Also the computer boards went thru some issues. ie; engine hours lost and remote shut down issues.

    If the boat is in S FL, let me know, the one we managed is down there supposed on the market.
    Already been thru the MAN issues.

    Try this, but you'll need to add on the the hydraulic swim platform length as this only gives the std platform. But I believe the factory replaced the std platform with the hydraulic so it's not a straight add on, but a net of about 2' extra so a LOA 60' 8" +/-

    Interesting
    That is the boat. Next to us, it was still a midget.
    Forgot the molded in stern platform was an overhang, then the hydraulic back porch.

    Have you been on one yet? What were your thoughts or impression about size then?

    We've got a 550. It handles Lake MI well, and it is well put together. It's a very good SeaRay but it isn't a Hat or well made SF etc. Size wise we were next to a 56 Hat and that seemed much larger in height and width, height of the deck, etc, but length wise it was actually identical, BUT as you know the Hat Ends at the transom (with a little swim platform in this case) and the SeaRay has 3-4" of swim platform that's counted in the LOA so wetted hull is good bit less. We now have a 56 Carver next to us and that is similar in overall size but it has more livable space , but also worse handling and build quality. Apples, Oranges, ...etc

    Member @Sea Gull owned a 58DB, I believe of that vintage, for several years. Perhaps he'll see the ping and chime in.

    Thanks, all. Still deciding whether to pursue or not...

    I've seen those dimensions, but without the drawings. That illustration looks like it does already include the added-on hydraulic platform... A 55' would be right at the upper end of our theoretical sweet spot; a 58' starts getting on toward maybe bigger than deciding on the spur of the moment to go get lunch in downtown Annapolis. Have to think about that.

    And of course the MAN maintenance $$$$$ regime. There's some kind of MAN maintenance capability around here somewhere, but I haven't looked that up yet. I know a couple boats on our dock have MAN V-10s, though, and they'd had on-going services being done...

    ChiTown, was I guessing right that the 2005/550 800-hp MANs are mechanical?

    Yes, we've got the 800HP 2848LE403's which are fully mechanical. If "I" had the choice I would have gone a year newer with the 900's and hydraulic platform, but happy with this boat for sure, and the 800's are supposedly very reliable. There is a lot of views on the MAN service. We did the full cooling service (this is the point of pain commonly referred to) before we moved it via Demann Marine out of Wilmington. It is recommended every two yrs but you should consult with your "local" shop as they can bore scope the heat exchangers to be more determinative. How much more "service" this is relative to other brands is a bit of a debate, many opinions, I've concluded it not to be a negative, or a least substantially so. It was a good experience w Demann, but MAN service is spotty for sure. FL has good coverage, but the Great Lakes is really just one shop. Other than that the engines have been great (1100+ hours) service wise. A boat with the Hydraulic platform is just over 60" for sure. I'm in a 60" dock and we fill it with no additional room, and it is 58'+. Captn J on this forum would have the most definitive view on the relative cost of MAN service IMO

    Thanks for that confirmation. The MAN model numbers and the engines listed in "for sale" ads weren't all that in sync, and then there are so many MAN model numbers... I've been sorta guessing, here and there...

    I suppose I could remove the hydraulic platform from a 580... and then maybe replace it with a Freedom Lift instead, if we were to get another tender. Theoretically, I like the Freedom Lift more than the TNT-like approach anyway...

    Significant expense to go that route, though, given starting with a functioning lift and only replacing it with a different sort of the same thing. I suspect there's not much of a market for used hydraulic lift platforms shapes to fit the stern of a 550/580.

    I have not owned one or ridden on one but I like the layout and love the steps to the bridge. I have been slip neighbors with 2 in the Bahamas. Which to me testifies to some amount of seaworthiness. But I realize a few have taken jet skis to Bimini. Chi town put it well when he said I have concluded it not to be a negative or atleast substantially so. 13 years ago before buying the boat I was scared to death of the MANs but a friend of mine convinced me to not let the MANs scare me. I do my service every 3 years. Provided you are comfortable spending the money having a professional do the service and go over things makes for very reliable boating. My MANs have been great to me but I have been great to them. On the lower Bay Ace Marine (same Ace that is in Vero) has a shop in Hampton. I have had them to do work on mine years ago and found them to be a reputable outfit. Don’t know how far up the bay they serve. If you like the boat don’t let the MANs scare you away. I keep up with MAN talk and hear the 800 and 900 common rail are highly regarded. Ranger if you like your Silverton this looks like a bigger version. Good luck.

    Chi town good to hear that your experience with Demann was good. Mine have been good as well. The owner is bit bragadocias but if you get past that I think he is honest and runs a good business

    Revisiting dimensions in the diagram...

    Looks to me in the upper pic that 54' 6½" is the length to the aft end of the original molded-in platform area... i.e., where the gunnels sweep downward to mate with the original swimdeck surface... That 54' 6½" correlates with the various USCG docs I've glanced at...

    And then the 4' (lower pic, and from doing the math) hydraulic platform is aft of that. And that correlates with the PBG "Length w/Platform... 58' 7".

    ???

    Looks like the hull has been around for a while. 560SB from 1998-2004. Redesigned interior layout in the 550SB in 2005 and the 580SB from 2006 through at least 2013 I think.

    Somewhere I read the same V-8 CRM block is making 1100 reliable HP now.
    That has to say something.
    With a good shop close by, don't be scared of the MAN engines.
    I ordered the oil from a Mobil distributor and filters from Performance Diesel in Houston directly for our past customer.

    ranger42c your dimensional analysis is correct for a boat with the std swim platform, although the 54'61/2" is to the molded hulls transom the 58'8" is to the end of the std platform. With the hydraulic its is a bit longer (60') as the fixed portion is cut back to around 2' and the movable portion is about 4'. If you don't want the hydraulic platform and and associated extra length get the 2005 550 which is the same boat and hull w/o the hydraulic platform but a davit. There are a couple on the market with the 900's I believe if you like those. The hull was new in '05 and is different than the previous 98-04 hull, especially in that it has no balsa coring, it is solid and/or uses non wood cormat. I got the actual hull layup engineering dwg from sea ray. It is a very good sea boat. Demann is a character but a straight shooter and does very good work at a fair price. I still get parts (filters, plugs) and advice from him. Good people for sure.

    I see what you mean about increased HP, but I can't tell for sure if it's the same block. Looks like the V8-1000, V8-1200 2868LE436?) and the V8-1300 (D2868LE466?) are all 16.16L, whereas the V8-900 (D2848LE423?) is 14.62L.

    I suspect close enough so it could be the same block, though... something related to the "D28" part of their engine coding maybe. The "6" could be a block generation" designator? The (second) "8" is number of cylinders (6, 8, 0, 2, etc.). The rest maybe version numbers?

    Thanks for that link. In the meantime I'd found one MAN service place near enough, and Performance Systems lists 3 (one being the first one I found) nearby. That helps.

    Thanks for clarification. And for the lay-up info! I hadn't noticed at first that there's at least one U.S.-based 550 with the 900s, but I do see that now... and I'll give them a look.

    There is a dedicated thread to the MAN 2848 engine on here. @mapism was a big contributor.

    Thanks, I've reviewed several MAN 2848 threads, don't seem to find one with mapism posts...

    Link?
