Nissan NSD40 Outboard Motor F.A.Q.

How do I start the Nissan NSD40 outboard motor?

To start the Nissan NSD40, first ensure that the fuel tank is full and the fuel line is connected. Set the throttle to the 'Start' position, pull the choke if the engine is cold, and then pull the starter cord firmly until the engine starts. Once it starts, gradually push the choke back in.

What is the recommended maintenance schedule for the NSD40 outboard motor?

Perform regular maintenance every 50 hours of operation or at least once per season. This includes checking the spark plugs, changing the gear oil, inspecting the propeller, and cleaning the fuel system. Additionally, flush the engine with fresh water after each use in saltwater.

How can I troubleshoot if the NSD40 does not start?

If the engine does not start, check the fuel level and ensure the fuel line is not kinked. Verify that the spark plugs are clean and properly gapped. Ensure the kill switch is in the 'Run' position. If the problem persists, check for any blockages in the fuel system or consult a professional technician.

What type of fuel should be used in the NSD40?

Use unleaded gasoline with a minimum octane rating of 87. Mix the fuel with a high-quality 2-stroke engine oil at a ratio of 50:1 to ensure proper lubrication and performance.

How do I change the gear oil in a Nissan NSD40 outboard motor?

To change the gear oil, place a container under the lower unit. Remove the drain plug and the vent plug to allow the old oil to drain completely. Replace the drain plug and fill the gear case with new oil through the vent hole until it starts to overflow. Reinsert the vent plug securely.

What should I do if the NSD40 overheats?

If the engine overheats, stop the motor immediately. Check for any blockages in the water intake and ensure the water pump impeller is functioning properly. Allow the engine to cool down before restarting and investigate any persistent issues.

How do I store the NSD40 outboard motor for winter?

For winter storage, drain the fuel system or add a fuel stabilizer. Flush the engine with fresh water and ensure it is completely dry. Remove the spark plugs and add a few drops of oil into the cylinders to prevent corrosion. Store the motor in an upright position in a dry, cool place.

What is the correct propeller size for the NSD40?

Refer to the owner's manual for the recommended propeller size, which typically depends on the boat's size and weight. A common size for the NSD40 is 9.25 x 10, but it's best to confirm based on your specific usage and conditions.

How do I clean the carburetor on the NSD40?

Disconnect the fuel line and remove the carburetor from the engine. Disassemble the carburetor carefully, soak the parts in carburetor cleaner, and use compressed air to blow out any debris. Reassemble and reinstall the carburetor, ensuring all connections are secure.

What steps should I take if the NSD40 is vibrating excessively?

Excessive vibration can be caused by a damaged or unbalanced propeller. Inspect the propeller for any damage or debris and replace it if necessary. Also, check that the engine mounts are secure and not worn out. If the issue persists, consult a technician for further inspection.
