LCI electric tongue jack - fix that worked for me - some oil

I have an LCI power jack on my trailer and it worked just fine for the first year and a half, then my wife tried to part the trailer from the truck and ended up over extending the jack, or so I thought, as it turns out after I bought a new Atwood jack, I took the LCI apart and found that the electric motor was full of water and seized. if i can find a replacement motor i can rebuild the jack and keep it for a spare or sell it. any ideas where i can get a replacement motor? TIA
