Hi , My A833 (cast Iron) has a leak that Im trying to locate, I replaced the seal at the tail shaft, the speedo gaskets, and the reverse lght switch, I dont see oil coming from the side cover area, the side with the fill plug is wet and also it looks ike around the inspection cover is wet, I tightened the fill plug could that leak, or maybe a seal on the front side above the inspection cover were the shaft comes out of the front of the case. thanks for any help!
