Removing a Yamaha F225TXRC Outboard Powerhead
Step 1. Remove the top cowling; the flywheel cover from the top of the motor; the ignition coil cover from the rear of the powerhead; and the intake silencer assemblies from the front left and front right of the powerhead.
Step 2. Disconnect the positive and negative power cables from the battery first, followed by the fuel lines.
Step 3. Disconnect the throttle and shift cables.
Step 4. Remove the dipstick and the dipstick tube that runs down to the oil reservoir.
Step 5. Disconnect the main wiring harness running to the controls and all the other wires, cables and sensors that lead from the outboard to the boat.
PRO TIP: Make notes and take pictures of where and what all the wires and cables were attached to and how they were oriented so you can reinstall them correctly when you rebuild the motor.
Step 6. Remove the left-side and right-side aprons and the rear cover that forms the lower cowling.
PRO TIP: Take the sets of nuts, bolts, washers and screws that you remove from various parts and put them in individual zip-lock bags, then label what's in each bag. If you don't keep everything separated and sorted, it'll be much harder to remember exactly what goes where when it's time to reassemble everything.
Step 7. Remove the six long bolts that run from the top of the upper casing to the powerhead and join them together.
Step 8. Lift the powerhead off from the upper casing and you're done.
