If your Suzuki Engine won't start or is hard to start, make sure the emergency stop switch lock plate is correctly positioned. Also, check if the fuel tank is empty and refill it if needed. Verify that the fuel hose is properly connected and not kinked or pinched; straighten or replace it if necessary. Lastly, inspect the spark plug and replace it if it's fouled.
Why Suzuki DF25 speed will not increase?
If the Suzuki Engine speed won't increase or the engine power is low, try reducing the load on the engine. Check if the caution system is activated and take appropriate action. Inspect the propeller for damage and replace if necessary. Also, ensure the propeller is properly matched to the engine loads.
Why is my Suzuki DF25 overheating?
If your Suzuki Engine overheats, start by checking the cooling water intakes for any blockages and clear them. Reduce the load on the engine. Ensure that the propeller is properly matched to the engine loads.
What to do if my Suzuki Engine idles unstably?
If the Suzuki Engine idles unstably or stalls, ensure the choke knob is securely pushed in (for manual choke models). Check the fuel hose for kinks or pinches, and straighten or replace it if needed. Also, inspect the spark plug and replace it if it's fouled.
How to fix excessive vibration in a Suzuki DF25?
If your Suzuki Engine vibrates excessively, tighten the engine mounting bolts or clamp screws. Remove any foreign objects, such as seaweed, tangled on the propeller. Inspect the propeller for damage and replace it if necessary.
