    Engine cooling system flow diagram

    I have a 92 270 sundancer with a 454, fresh water cooling.
    Does anyone know where I could locate a water flow chart.
    I didn't pick the boat up yet, does it have a front engine mount water pump or does it depend on the leg?

    I've been running a berkeley 12JE jet since 1977 so I need all the help you gentlemen can provide.

    Thank you

    Re: Engine cooling system flow diagram

    There may some available somewhere online, but I do know that a Seloc service manual (usually about $30-$40) will have the flow diagram, along with the other stuff a service manual will have. The Merc svc manual is more complete, but the Seloc's are fine.

    If you have a Bravo drive, you have a sea water pump mounted on the engine. If you have an Alpha, the pump is in the leg.

    Thank you, it has the Bravo, is it then like a car type water pump or strictly a marine? Please excuse my lack of knowledge on these boats.

    Both actually. It has a circulation pump just like a car that curculates the water through the engine. It also has a RAW Water pump that brings in lake water to the cooling system.

    Re: Engine cooling system flow diagram

    I can see I'll have to pick up a manual. Is the raw water pump also belt driven? Is that the pump I hear people talk about changing the impeller in?

    And, yes, belt driven. It's on the bottom, forward, starboard side of the engine. It will have (2) large (1-1/2"?) hoses on the aft side.

    If you don't know when the impeller has been changed last, put that high on your priority list of things to do.

    Thank you very much for your info. Where's a good place to buy the replacement parts?
