Motor overheating when trolling

[fishin2]

No,nothing missing. Was just a little dry and I replace it every other year, needed or not. Only had the boat 2yrs and this is the first time pullin boards with it and she got a hot at an idle. Gonna check into an impeller housing today, just might be the way to go, replace everything and eliminate that possibility. Thanks fellas, your always a great help, Mike
