Overheating can cause 2 stroke outboard motors not to reach full RPM. When a two-stroke outboard motor is running, combustion is always actively taking place in the combustion chamber. This creates a lot of heat in the process. Without properly regulating this heat generated in the engine during combustion, the outboard motor can be easily damaged.
