Sea Ray 580 Sedan Bridge?

I only heard of that remote oil filters placement (which in fact I mentioned at the end of post #27), but I've never seen one in flesh.
Do you know if it's an original MAN part, and if not where it could be found?

Performance Diesel rigged the MAN engines for SeaRay.
It looked like a factory setup but so did the clutch oil cooler mounting (TD5114A) that was fab'd by them also.
I'm sure they can either offer the part number or sell you the kit.
I archived all my pictures from those boats. Digging them up may take a bit. Maybe a current owner can send you a pic from their rigs.

The rigs I worked on had them further in.
I remember now, the forward cartridge was just inboard of the raw water pump.

That leaking drain plug in the picture is a typical issue with those assemblies.
The plug screws into a bushing, that is coarsely screwed into the casting.
If you over tighten the plug, on next removal, the bushing is loosened or comes out.

Also note the clutch oil cooler. This contains the only zinc for the engine assembly. The MAN engine uses NO zincs.

Bottom rite of the picture is the original raw water pump for the ships A/C systems.
When the propeller shaft log composite seal starts leaking, this pump motor is gone.

Many thanks for sharing your photo, that's very interesting.
I just went down in my e/r to check the feasibility of using the same kit, but unfortunately in that area I have the raw water steel pipe outlet, just before it splits to feed the wet exhausts of each cylinder bank. And relocating that would be a nightmare.
Oh, well. At least I tried.
Good thing that in my boat, even if pretty tight, the access to the outboard side of the engines is still manageable...

I couldn't agree more, but it's one of those things you have to live with, if you've got those engines.
BTW, I never noticed that they dropped the spin on secondary fuel filters in the latest blocks.
Some German engineer must really love the cartridges, for some reason!

There are probably still 10,000 or so of these filter assemblies on a shelf somewhere.
Cast to fit that oil cooler that was cast to fit the side of these blocks & designed-cast to point up away from the boat hull stringer.

If you could just remote mount generic spin on oil filter assemblies. Point them down and glue them where you want them.
Hummmm.
As soon as that mfg warranty is out, I'd go here.

Or, just go in there like a good boy scout and change them like everybody else does.

Good question. I wish I knew the answer!
But at a guess, you might be correct with your thought of better protection.
In their normal placement, the oil filters stick out from the rest of the engine and are indeed are a bit exposed, when they happen to be on the inboard side (i.e. port engine with straight shafts, or stb engine with V-drives, as I have in my boat).
The cartridge covers indeed look solid enough that you'd struggle to break them if you would try with a hammer!
But in the remote placement which you showed in your pic, there isn't even that problem, because they are not in the way at all.
Though they might have just thought to use the same parts, which makes some sense...

LOL, for some reason that sounds familiar!
Not that this is only true of MAN filters, mind.
Contorsionism is an essential skill in any boat, either for this or for any other hard to reach equipment...

Diabolical is speaking kindly of the CAT design requiring torture, pain and lots of blood letting while servicing 3208s in some boats I have been around.
I thought a Fleming install sucked until I lost all my blood working on a 34 Viking Convertible with 3208TA's.
Raw pump access, hard oil filter access and any routine service cringed my back working on this Sadistic device.
I had to pass on the job to replace a failed clutch on this same beast.

I think somebody looked at a 3208NA and thought tight but it will due, then ordered a 3208TA.

AND, I'm a 3208 fan, just not in tight spaces.
