Also, change the oil filter at the same intervals. ► General maintenance tips: Use only recommended oil, keep the propeller clean, and ensure that the fuel system remains uncontaminated. ► Common issues and solutions: Water in the fuel can cause rough idling; use a water separating fuel filter to prevent this. Another issue is an overheating engine which can be due to a clogged water intake; regular inspections and cleaning can prevent this. Five Maintenance Tips: 1. Always flush the engine with fresh water after each use, especially in saltwater environments. 2. Inspect the anodes regularly and replace them if 50% worn. 3. Check fuel lines for any signs of wear or cracking and replace if necessary. 4. Clean or replace spark plugs annually. 5. Store the outboard motor vertically or in the tilt position to ensure no water remains in the unit. Tuning Tips: ■ Upgrade to a performance spark plug for improved combustion. ■ Fine-tune the carburetor for better fuel and air mixture. ■ Upgrade to a stainless steel propeller for better speed and durability. ■ Use high-quality marine fuel additives for better performance. ■ Regularly check and adjust the throttle and shift cables for smoother operation.
