I was out on a local pond this morning and my outboard overheated. I froze my azz off but the motor overheated. It's a 1998 20 hp Evinrude 2 stroke. I figure it's the impeller because when I first started it at the launch, yup the icy launch, it took quite a while for the water to start pissing out the outflow. Thought at first it might have been iced up but once it started it stayed week. When I cut her down to trolling speed it took about 15 minutes before the overheat alarm went off.
Anybody got any pointers on replacing this. Never done it before. This is a new to me boat and I don't know when, if ever, its been changed.
Thanks
Glen
