    Question Closed circuit cooling of Interceptor 289

    Was wanting some information on installing a heat changer on my 1964 289 Interceptor I want to put a circulation pump on the engine I am assuming I would have to change the timing cover to install the new pump and to fit the fuel pump?
    Any info would be appreciated

    If the engine was ever used in salt water, it is not advised to go to fresh water cooling.
    My Motto Is:
    K.I.S.S.- Keep It Simple Stupid!
    Or, It Might Get Real Expensive!

    Hi, from what I understand it has never been in salt water and water jackets look pretty clean motor runs real well but live in Auckland NZ surrounded by saltwater!

    If you do install a Closed Cooling system, do this:

    After approx 20 hours run time, remove the H/E, perhaps even shake it up a bit, and dump the coolant into a clean white bucket.

    Examine the coolant for rust scale debris.
    This will give you an idea as to whether rust scale is sluffing into the coolant.

    Re-install the H/E.
    Filter the coolant, and re-install it.

    After another XX hours amount of run time, repeat the process.
    You should eventually see a reduction in the amount of rust scale debris.

    At some point, new fresh coolant could be installed.

    I have an old Eaton Marine closed cooling system off of an FE Interceptor engine with all the plumbing, no pump though. Worked off the raw water pump and a recirculating pump... This is not the typical clunky system found on Chris Craft engines. I posted it for sale on the forum.

    Hi Thanks, have resolved heat exchanger going with a Savage engineering system bolts pretty much straight on! needed to change raw pump (Couldn't find parts for mine) to a crank pump , timing cover and installed circulation pump.

    You won't be disappointed with the crankshaft pump. Good call!

    Hi Rick, hopefully right call, still quite away before I get the boat back in the water and still trying to sort out pulleys to make sure it fits, the one on the motor was too small!

    I am looking at adding a fresh water cooling system to my 1960 312 as well. It has been used in salt water a bit. We are breaking the engine down now and it shows very little rust/pitting. It will be completely cleaned and freshened up. What is the issue with adding a closed system to a salt water boat? Does anyone know who/where I can find one?

    Thanks,

    Karl

    The issue is the engine's coolant passages will collect a lot of the debris and precipitate over time.....if you are rebuilding the engine, hot tank the block and find the passages clean, you are probably ok adding the closed system......

    I have no clue where to find a complete system.....piecing one together wouldn't be hard, just time consuming collecting all the pieces....
