Hello all, hope someone can help me, I have a 1990 350 sea ray EC with 454 mercs, raw water cooled, are my engine temps ok??, I am attaching pics of my port and starboard engines, running at 2500 rpm. The boat have been running great for almost 90 hours at those temps, since I bought her last year, but I am bit worried, that maybe its running a bit hot, Should I replace my impellers?? Any other recommendation?? thanks
