    I just noticed there is something other than just water coming out of my starboard engine cooling water. It looks like oil, but I am going by appearance only.

    I have T/454's with closed loop cooling. Engines under 400 hours

    Any advice as to a plan of action? Could this be a leak from the oil cooler?

    Hi,

    Is this water that comes out over the side?

    Does it feed the Oil Cooler, trans oil cooler?

    Cooling water

    The cooling water circulates through two small (2" diameter) tube bundle type coolers on either side of the engine. I believe they are for the engine/transmission oil.

    There is also a larger heat exchange for the water/glycol engine coolant.

    The water also cools the dripless seals.

    It is drawn out of the lake from under the hull and exits out the exaust tube.

    I have only has the boat since last summer and just noticed this yesterday while warming up the engines.

    Hi,

    From what you have written I would say there is a better than even chance that one of your coolers is leaking.

    Does either of the engines or trannies use oil? (In the engines case-more than when you first got it)

    A little oil can show up a lot in clean water.
