PRO TIP: Collect the nuts, bolts, screws, washers, etc. from each component as you remove them, then put them in a zip-lock bag and label it. It'll be much easier to find the correct part for the correct component when the time comes to reassemble the motor.

Removing the Electrical & Fuel Systems From a Yamaha F225TXRC

Step 1: Take pictures of the motor from all angles to document all the different connections and couplings, so you can reference the pictures when reassembling the outboard.

PRO TIP: Continue taking photos of the motor as you disassemble the various components, because some connectors and fastenings are only visible once other parts are removed.

Step 2: Remove the wiring harness. Work around the motor and disconnect the electrical connectors, trying to keep the wiring harness in one piece as much as possible.

NOTE: Be careful with the harness' connectors because if you break one, you may have to replace a large part or all of the wiring harness.

Step 3: Remove the vapor separator tank. The VST can be removed with the various hoses still attached to it. Don't forget to disconnect the water line that attaches to the fuel cooler.

Step 7: Remove the flywheel. Make sure the three bolts in the flywheel puller are set at the same distance down, so the flywheel is pulled up evenly and doesn't twist or warp.
