Is this engine raw water or fresh water cooled? Sounds like blockage in the raw water system, which could mean the engine (if raw water cooled) or the heat exchanger (if fresh water cooled). Is a strainer installed in the inlet? If not, you could have debris blocking the passages. A backflush with fresh water may help if that's the case. If the engine is raw water cooled, you could have scaling and then you may need a flush with Rydlyme Marine or oxalic acid.
