Outer Limits 4x4 Board

Hi there, have a 10,000lb low mount warne winch, just turned it over and heap of rusty and black water came out of the moter side. Truck has been kept out side past 2 weeks and had plenty rain. I noticed there are a couple 5mm slots where motor meets backing plate, these are at the top, am assuming water getting in there, are these slots supposed to be drainage slots and there for at the bottom or are they breathing slots and need to be at the top. The motor is new and came from Hobzeys 4X4, it came fitted with a breather which is also at the top with the slots. Am thinking of trying to remove the motor while still on bar and turning so slots at bottom???
Or do i drill a little drainage hole?? Or maybe just silicone the whole thing, but then nothing can get out if it does find its way in??
Any feedback be much appreciated.

i did find a tiny phillips head screw at the bottom that seems to be a drainage hole??

I would just silicon it up and run the breather up into a high place.
I use a airbed pump that blows air into 1 end of the motor when winching in and vents out through the breather, this helps to keep the motor dry aswell as cooling it.

1 thing you need to remember to do is after a trip out through water crossings or bog holes. run the winch cable in and out a few times to dry everything out.

yeh cheers i agree, i got off my ass and fitted the hose to the breater and put a min filter on the end and ran it up inside the tube on my bull bar. Thnking i will silicone it up and just make sure i remove the little screw i found there to make sure no water inside.
