Took it out today and ran the crap out of it for an hour.
I thought it sounded different, but could have been my imagination.
Wife thought it ran better than before. As I was getting trailer, I looked over and she's racing a 4 stroke Kawasaki down the lake. She said she beat him that way, but he handled the wakes better on the way back and was even when she turned for the dock.
So if it dies, it went down fighting.
I fogged it before I took it out of the water, and crossed my fingers.
