    Do servo (male/female) connectors work in water?

    I recently researched and discovered a mini-sized, IP68-rated waterproof servo offered on AliExpress. Link to the servo is below…

    https://www.aliexpress.us/item/3256809732088602.html?spm=a2g0o.order_detail.order _detail_item.4.5bf3f19cA9AeK1&gatewayAdapt=glo2usa

    Mini-servo seems perfect for a narrow bow installation. I just ordered it. The plan is to connect it to actuate the Revell Gato bow dive-planes retract mechanism.
    I’ll run a servo power/signal line (extension) out the front WTC bulkhead to lend power the IP68 servo.

    Anyone think it’s necessary to waterproof the black plastic Futaba/JR servo connectors?

    I think the connectors corrode pretty fast when they get damp so I'd put something around them. Look at the wires carefully because water can get in that way too.

      By the way water proof, is only Splash proof.
      look up for "diy water proof servo " at YouTube.

      Try to replace the servo connector with Dean's 3 pins connector, I think they are plated for corrosion. Apply some DeoxIT will also help.
