Got up to Rayburn Thursday night, charged the batteries a went out Friday mid morning. Ran up the Attoyac to the high lines but hit the muddy water so turned around and headed back towards main lake. Fished a few piles then moved into the timber. When I was coming in I noticed the big motor started making a strange high pitch sound, then it shutdown hard like I had hit a stump, but didn't hit anything. Fortunately the TM batteries had a good charge on them because I had to go by trolling motor for quite a ways before a couple of guys came by and gave me a pull back to Jackson Hill. Hauled it up to Center on Saturday, they called this morning and said the lower unit was locked up. It's gonna be an expensive fix, but not near as bad as it could of been. Decided to have them go ahead and put on a Hamby's Keel Guard while it was there. They said they should have it finished and ready to go well before I get back up there on the 14th.
