    Intercooler CLOSED LOOP cooling? 12v pump and 2nd water/water cooler

    Hey guys as always a huge thanks for all your advice!

    This applies to all external intercoolers, indipendent of ski model

    So I have a 2004 RXP stage III, ride in salt water with XS style intercooler, always rinse with Salt-Away, yet every 2-3 years the intercooler leaks water into the intake.
    Since I am fed up with the salt water corroding the intercooler, what about this?

    Intercooler installed normally, yet works in a closed loop with antifreeze. So a 12v Bosch style pump to circulate the water from the intercooler to a 2nd WATER/WATER cooler. So in 2nd cooler hot antifreeze from intercooler gets cooled by raw sea water? And a small expansion tank for it.

    -Will this cool the water enough for cool enough intake temps?
    -Will the skis 12v system be adequate enough to support a 12v pump running all the time?

    Get yourself a quality intercooler instead of the XS, save the weight in your ski, put all that extra money into a Good IC, i rode in salt for years and never had an issue.

    What would you recommend? Over here in the Med with the salt at its highest, they all seem to fail.

    I would just keep changing out the XS IC every 2 to 3 years. Cheap enough. Even here in New Zealand I only pay $190nzd for one.

    you need something that has a ZINC anode you can monitor and change out often to protect the IC

    Is there anything with a copper core, instead of aluminum? Apart from the RR one.

    Yes you can. You can drill and tap the front or rear water tank or install a tee fitting at the intercooler inlet or outlet. Make sure some of the metal threads on the anode fitting are touching metal. It needs to be connected electrically in order to do its job.
