I have a lot of OMC 3&4 with VTR upper cover from 1968 thru 1975 and ALL runs very hot.
I suppose the reason is the flat exhaust plate without cooling interspace on it .
On the older 3 the the metallic airbox fixed on it act as an "heatsink" , and the lower open cover allows a good recirculation of air…
The covers of 1968/3 and following 4 are completely sealed …
