Hi Everyone, I’ve learned a lot reading other threads and hugely appreciate your willingness to share knowledge and support each other.
I have a 1973 Ericson Mk II with an atomic 4 that is new to me as of last summer. I’m having issues with over heating. It stays at 170F at about 2.5 kts in speed (sorry my tachometer is not working). If I go any faster it starts to over heat.
Water coming out of the exhaust has decent flow but is NOT hot when the engine starts to overheat (180+ degrees).
The coolant also doesn’t seem to get that hot.
The engine has a heat exchanger and I would appreciate any suggestions tips as to where to start in solving this issue. I’m assuming I should be able to get my boat up to 5+ kts using an atomic 4, right?
Pictures attached.
