How do you set the timing on a 2001 90 HP Johnson?

To set the timing on a 2001 90 HP Johnson outboard motor, first ensure the engine is in a secure position and the boat is on land. Use a timing light and connect it to the number one cylinder spark plug wire. Locate the timing marks on the flywheel and align them with the specified marks on the engine block while adjusting the timing by loosening the stator or trigger as needed. Finally, recheck the timing at various RPMs to ensure proper adjustment, then securely tighten any components that were loosened.
