I hit a log, turned it into my insurance but nobody can find anything wrong with the boat around my hometown. Only run 100% gas, use Mercury gas treatment #2 (have ever since I got the boat, 11+years), boat does not and has never taken on water, RPM's at 5300; after I hit the log I put a 8" jack plate on the boat. Motor is at 3" below bottom of boat (thats up 2.5", H2O is 12psi, and RPM's still at 5300 just like it was before jack plate. I need someone to inspect, check out and let me know what is wrong. Insurance will pay to fix but they need to know what is wrong.
