The correct spark plug gap for the Nissan NSD70A2 is 0.9 to 1.0 mm (0.035 to 0.039 inches).
First, check the fuel level and ensure the fuel line is free of clogs. Verify that the kill switch is in the correct position and inspect the spark plugs for wear or damage.
Use a high-quality 2-stroke outboard motor oil that meets or exceeds the manufacturer's specifications.
Rinse the motor with fresh water after each use, especially after saltwater exposure. Apply anti-corrosion spray and store the motor in a dry environment.
Stop the engine immediately and check for blockages in the water intake. Ensure the water pump is functioning properly and that coolant levels are adequate.
Drain the fuel system, lubricate all moving parts, remove the battery, and store the motor in an upright position in a dry, cool place.
Remove the lower unit, access the water pump housing, take out the old impeller, and replace it with a new one, ensuring correct alignment.
Maintain optimal engine tuning, reduce unnecessary weight, and ensure the propeller is correctly sized and in good condition.
