    Just purchased a new to me 2018 460 Sundancer. Need some advice on fluids for top off. Unfortunately, previous owner did not leave any on board. Owners manuals are a joke.

    Cummins QSB 6.7 with ZF Trans. (straight shaft)

    Motor Oil?
    Coolant?
    Trans Oil?

    Thanks in advance,
    Kirk

    Checkout sbmar.com for a ton of specific information on Cummins engines, I noticed on there users are all over the map regarding oil types, 15w40, 5w40 synthetic, etc. However, I would check the service records, and see what was added in the past, and use that.

    Cabo now '05, Cummins QSC's, Furuno, Westerbeke 7.6
    Cummins QSCs
    Oil - Almost certain any diesel 15-40 like Shell Rotella T4
    Trans, you def need the model number of trans to look it up on the ZF sched. They are very liberal with types it takes (literally can take dozens of types, but you need to know model ZF).

    If you post the model # we can help you navigate the list.

    Coolant, eh, can't recall.

    Hopefully a 2018 model year boat is not consuming any of those mentioned fluids regularly??

    Perhaps you just want them on-hand but you also mentioned "top off"...that might be concerning...

    Thanks for the info. I called Seaboard. They were very helpful.

    Not consuming any fluids. Just want to have fluids in case and when I need to change the out.
