Yamaha T60 Outboard Gearcase Removal

Step 1. Get the outboard lifted and tilted to make it easier to remove the parts that hold the lower unit to the rest of the outboard motor.

Step 2. Use a 14mm wrench to remove three of the four exposed main bolts (two on each side) that hold the lower unit up to the rest of the outboard. Loosen the last of the four bolts without removing it to keep the lower unit from dropping off.

NOTE: You can remove all four bolts in this step, but leaving one on loose is just a precaution to keep the gearcase from falling off during the removal process.

Step 3. Use a ratchet and 12mm extension to remove the bolt at the top that holds the trim tab anode in place, then pull out the trim tab anode.

Step 4. Remove the 12mm bolt inside the opening at the bottom that was exposed after you removed the trim tab anode, followed by the last of the four main bolts loosened but not removed in Step 2, then gently pull down the gearcase. 

Step 5. Disconnect the speedometer tube, then pull the lower unit out completely and you’re done.

As mentioned before, removing the gearcase on an outboard is usually the first step to being able to complete other outboard maintenance and repair jobs, such as replacing the water pump. Watch the video below to learn how to replace the water pump on a Yamaha 60HP outboard engine.
