Make sure you pull the prop and check your seals. If the rope made it down to the seals it probably melted them.
Already pulled it. Didn't seem like it got to the seals. Still going to changed the lower unit oil a few times over the next month or so to check for water intrusion.
Believe it or not, sounds like you got lucky. Could have been worse.
OTH, it's good practice to check both props after each trip to the lake.
