    Good Day All!!

    I have recently taken over a 104' Broward, 1984 with 12v92a Detroits. The crew changover wasn't exactly harmonious so I didn't get a lot of inside scoop from the previous Captain.

    I recently took her out for a little spin and got "Low Gear Oil Presure" alarm on the starboard DDEC system. I never lost any propulsion, as far as I could tell, and the gear oil levels are perfect.

    When I took her back to idle in neutral the gear oil pressure dropped to zero as opposed to about 100 on the port side. Re-engaging her got me up to about 80.

    Anybody with similar experience that might point me in the right direction?

    Many thanks in advance for any help and . . .

    HAPPY HOLIDAYS EVERYBODY!!!!!

    ROCKY

    If you've been good, maybe it's just related to a hung-up diverter valve in your Twin Disc gear, assuming they're not ZF.
    Did you already check the sender against a mechanical gauge?
    You will still need to get real expert advice from a tranny mechanic, plenty of whom are in your area.
