Dear Bob:
Q. My boat is equipped with a MerCruiser 7.4L Bravo One package. I am having a high speed overheating problem and the local marina is having trouble figuring it out. They’ve replaced the raw water pump, thermostat, and exhaust risers, but the engine still overheats at higher rpm. Any suggestions you can provide would be awesome.
Thanks,
Todd Walker
