If you had the cooling system of an engine two or three times the size the coolant temp probably wouldn’t vary at all above about half throttle.
But if your coolant is too eager to rise in temp then some component of the system is limiting the ability for the cooling system to cool the coolant. Sounds cool huh? haha. Put another way the coolant temp is too sensitive to load.

When I see that on my boat I need to rod out the flues in the coolant heat exchanger.
