I've got an 8.1 L throttle bod injected Marine Power with 212 pump on my North River Commander. I've been having issues with it overheating at low RPMS. It did it to me in Seward last week as I was leaving the Harbor. I had just got to the outside buoys from the back boat launch when my alarm went off. it did again today motoring around a local lake. Antifreeze level seems ok. No leaks that I can see from anywhere.
If I run on step, it stays cool in normal operating range.
Anyone have any ideas or ran into this issue? Motor only has 200 hrs on it.
Thank you in advance
