I have a question for a different STX 38. It is a Hydro with a black deck. It had sat out all last summer and most of the fall. I have gotten it running well. The only problem is when I push or pull the hydro. It is going forward pretty well, but pulling it into reverse is extremely hard. Is there something I can do to remedy this? Anywhere to grease? Any input is again appreciated! ( I have three of these and am trying to get them all fixed)
