| 25BMHS/L Features |
Manual Trim & Tilt method Loop charging - Loop-charged scavenging creates a circular flow for efficient removal of exhaust gas and even distribution of air-fuel mixture. The result is greater combustion efficiency for higher power and better fuel economy. Engine stop switch lanyard - This lanyard clips to clothing or around the wrist, stopping the engine immediately if the operator leaves the helm. Shallow water drive - The outboard can be set at a tilt angle, preventing it from hitting the bottom when operating in shallow water.
