    I should be taking delivery of a factory recon QSB 440 very soon. I’m looking for advise on what Seaboard items I should get onto my motor before I install it. Also, anything that would be worth buying from them to do with the fuel filtration and alarms. All advice is appreciated, thanks

    Custom made SS exhaust elbow with the ability to add an EGT probe.

    I believe Cummins also offers kits that allow you to relocate engine mounted fuel and oil filters should the stock engine location not be suitable for easy routine maintenance.

    you will need good fuel filtration setup if you dont have a racor 900 or better with 1/2 fuel lines min right now. What about cabin bus heater? You may need valves for that. Block or Oil pan heater? I like gauges, pyrometer is nice, trans pressure. They have cool digital gauge panels now.

    Why not get Tony's recommendations. Then you can pick and choose what you think is necessary for your application. A custom SS injection elbow would be good, but I would want to fit the engine into the engine compartment first to get all of the measurements right.

    A simple heat alarm on the exhaust hose. QSB’s start with no smoke at all even in 35 Deg. temp. Heat is not necessary except for extreme conditions. I never had water pump problems with the stock pump. Some people switch to Seaboard pumps. The exhaust design is probably the #1 most important item. Downstream water injection and exhaust height is priority. Oil change system is handy and clean . It also keeps you from putting it off due to the ease of use.

    Raw water alarm set up is something I would like. No one can watch their temp gauge all the time and often alarms come too late or never.

    I'm a Tony Athens Seaboard Marine fan and friend. No commission on any sale.
    He engineered my last three re-powers. I bought my 6BTA 370 s and the gears required.

    Here's my list before you drop the engine in. Plan it out.

    Wolverine Oil Pan heater pad
    Wolverine Oil Pan Heater - Model 25 250 Watts - Seaboard Marine

    Install a permanent drain line on the back of the oil pan. I have the lines on the 370s I've installed. Pump the pan out in a minute or so with a 12V Water Puppy with a neoprene impeller. Zoom in, the 370 is in my 25 T Jason

    Double Fuel Filtration WIF common rail
    SMX Double Double Multi-Stage Quantum Kit - Seaboard Marine

    But most importantly, if you haven't already, read all you can on wet exhaust design and safety especially the spillover height to the engine turbo from the waterline.
    Everything you Need to Know About Marine Exhaust Systems - Seaboard Marine
    I'm not sure of the height of your install. Maybe the height is enough to use the stock
    Cummins wet elbow.

    While the QSB 5.9 is out, consider an inline raw water alarm.
    Complete Raw Water Flow Alarm / Detector Kit - Seaboard Marine

    This QSB 5.9 has the fuel cooler removed.
    Modified QSB 5.9 with Fuel Cooler Removed - Seaboard Marine

    Just a few add ons to consider IMO.

    All great suggestions! I will reach out to Tony. I was thinking of the water flow guage. I think I saw it on here recently. I really like the oil change tube. I assumed that came on the motor. I'm being told we are getting a 90 degree dry elbow that Cummins offers and then when the motor is in try to get that up to the highest point we can before the mixing elbow turn back down to the bilge. Our biggest problem will be the exhaust. Not much room with the wet keel for the lift muffler we are considering. Is a surge tube and straight 6" muffler a possibility? That's what the old motor had but without the muffler. The wet keel is close to the waterline and the motor not too much higher.

    I agree with BillD.
    No need for a Reverso oil pump. My engines and transmissions are plumbed to a common manifold with valves where I attach a 12v oil pump for oil changes.

    Also if your engine has a intake air preheater you might consider deactivating it. Most engines run fine without them and they put a significant load on your alternator when they cycle on/off.

    Can you fit a 6" horizontal Centek muffler with a 6" exhaust under the deck ? I'd have Tony sign off on any exhaust design you go with.
    I had Tony build this customer exhaust for my 25 Terry Jason.

    Should that temp alarm for the exhaust/raw water loss be on the hose or on the mixer? I always thought it should be on the mixer, but it was just an assumption. I can tell you I tested it out on the mixer the hard way, and it sure does work. Saved me from totally chewing up an impeller.

    Borel wants it mounted on the hose. Other manufacturers may have different requirements.

    It needs to be mounted on the hose in order to dampen out the high spot exhaust temps that come out of the mixer as the exhaust/water stream is not mixed well until it travels down the exhaust hose a few feet.

    I first installed mine on a fiberglass connector and it would alarm spuriously when I throttled back to near idle after a high load run. Moved it to the exhaust hose and it stopped.

    Thanks BillD and ARC and all. I can fit the 6”” muffler under deck but might need an expensive version that is longer and not as big around. That’s a nice custom riser BillD but I think it wouldn’t be able to be that high and under deck on my boat. The pic ARC put up might work. Is that custom or a Cummins riser and standard mixer after it? Here’s a pic of the 210 and we are thinking the 440 will be lower in the bilge because we cut and lowered the pan. When the motor arrives a lot of questions will be easier to answer.

    FBE43F69-E7C4-48A8-A7C5-4249C352EAD1.jpeg My old set up was Cummins. It was fine until something goes wrong. Then the water could possibly if not definitely go into the turbo. I was not willing to wait for that to happen and ruin a 50k engine. So I had Marine Manifold of NY make me the proper set up. Now all water is down stream no matter what.
    This was the original Cummins. You can see the water is going up hill

    Did you change the shaft tube? or gear angle?

    pretty sure the QSB ReCon 5.9s do.
