We have a slow dripping leak in our inboard engine. Attached is a video. Any thoughts on how to fix this?

Looking at the water trail and corrosion, the water appears to be coming from the vent hose on the "dripless" seal. Try carefully tightening the hose clamp where the red hose meets the dripless seal face holder. Be very careful with securing that hose as it can sink the boat if it comes off the nipple. .

Sorry my other post was on my Iphone at the GYM.
But anyway as said be careful and try to tighten clamp on the red hose
and if if it is loose.
But also the whole packing is very dirty looking and be not giving good sealing
also and causing leaking when motoring,if it is a PSS dripless go to there web site for more info and I just did my PSS when I hauled for new bottom paint.
I took it all apart and sanded and cleaned all surfaces so they meet nice clean
surface and looks like new and no more leak while motoring.
If you try taking it apart in water it will let lots of water in boat and maybe too much so that is why I waited until I hauled to take apart and clean and I also replaced the black rubber booth.
