    I’d like to upgrade my motors gear oil cooler, as I’m now experiencing external leaking on my second oem unit, obviously not designed to survive in the real world. There’s no zinc, and they’re obviously thin metal.
    I’ve got a 6 BT, 180 hp, with a TD 506 transmission, 1 1/4” raw water hoses.
    The problem is selecting from the 30 some coolers offered in the catalog here!

    How to measure Gear oil cooler

    Have we failed here? With literally 100’s of variations of gear coolers sizes out there, we put this there to help..

    Tell me what we need to to do to make it better.
