Newbie here. Put the boat in the water a few weeks back and it ran like a top. No problems at all. Then we sucked up a tow rope. Put boat on a trailer to cut out rope, no issues but when backing the trailer up the hitch detached and the boat (still on the trailer) ended up with the stern in the sand. Not a hard contact with no visible damage. Put boat back in water. Started up with no problems.
When accelerating after, we got an overheat warning. Figured there was something clogged with sand. Checked everything obvious at the stern - nothing. Restarted and ran for an hour with no problems.
For weeks now this pattern is repeating, sometimes you get an overheat warning and it won't go away. Other times, you get nothing and it runs fine for hours. Sometimes you can turn it off for 5 minutes after the warning and then it is fine; other times the warning keeps coming back.
I have checked the WTS and EGT sensors and their resistance is within spec. No visible leaks anywhere from the cooling system. If it was clogged somewhere I would expect to get the warning consistently. I am stumped.
