We have a 2008 Bavaria 31 and have experienced an overheating problem with the motor. On investigation there is very little ventilation to the engine bay, and no blower or other means of extracting the hot air. We live in the tropics in Queensland, Australia. The seawater temperature is now heating up to 26 degrees celcius. The boat is almost 12 months old. We didn't have the problem in the winter. Has anyone else experienced this problem?
