    Riva Gen3 intercooler and cooling upgrade, oil cooler water discharge question

    I just installed a slew of parts in my 2018 GP1800 Riva Gen 3 Power Cooler, Cooling upgrade, Intake ribbon delete kit, power filter, breather filter, solas prop. I have the retainers left to do.

    Tonight I cranked it with a flush hose, ran fine. I did notice there was no water coming from the portside overboard discharge (from oil cooler).

    Is this normal?

    If that's the cooling line fed by the pump, then it won't have any water output because the ski isn't actually pushing water through.

    Your right, I was walking the dog this morning when out of nowhere, I pictured the cooling circuit in my head, then it hit me like a brick! It occurred to mew then that the oil cooler has no coolant while on the hose.
