To increase the speed of a 25 hp Johnson outboard motor, you can consider several modifications. First, ensure the motor is well-maintained, including clean fuel, a new spark plug, and a properly functioning propeller that matches your boat's design. Upgrading to a high-performance propeller can enhance speed and efficiency. Additionally, reducing the weight of the boat and optimizing the hull's condition can help improve overall performance.
