Yamaha 60HP Outboard Timing Belt Replacement
The timing belt on a Yamaha outboard should be changed every 3-4 years, especially if you haven’t inspected or replaced it on an older model.
Like any other rubber piece, the timing belt will deteriorate and crack with age, which could result in serious engine damage if the camshaft stops and it bends the valves. A timing belt is not an expensive part, and it makes all the difference in the world to have one in good shape that can last for years.

Yamaha T60 Outboard Timing Belt Replacement
Step 1. Remove the cowling and disconnect the battery.
Step 2. Lift off the cover, which is held in by rubber grommets. Push up on it to release all four corners.
Step 3. Bring the engine around to top dead center (TDC) if it isn’t already.

Step 4. Remove the flywheel bolt by using an impact driver to take off the 30mm nut at the top.
NOTE: At this point you want to double-check that the engine is still at top dead center in case it moved out of TDC position.
Step 5. Use a Yamaha puller tool or a three-jaw puller to loosen and remove the flywheel.
NOTE: Before you lift off the flywheel, make sure you’re still at TDC.
Step 6. Remove the stator couplers, the pickup coil couplers, and the stator itself, which is held in place by three 8mm bolts.
NOTE: Notice the orientation where the stator came off. There's a little notch where the wiring passes through. Make sure you get it back in the same position when you reassemble everything.
Step 7. Remove the pulsar bracket for the stator using an impact Philips and a soft-blow hammer to break loose and remove the bolts that hold it down. Use a light counter rotation, and pop each bolt with the impact and the hammer.
NOTE: Don’t use a regular Phillips screwdriver, as you may end up stripping the heads.

Step 9. Remove the two 10mm bolts holding the pipe, then set the pipe aside to give you more room to work.
Step 10. Remove the woodruff key, then loosen up the tensioner and push it to the most relaxed position.
Step 11. Recheck your timing marks one more time to make sure they’re aligned, then lift the old timing belt off.
Step 12. Install the new timing belt, making sure the numbers are in the upright position, then release the tensioner on it.
All that’s left to do now is to put everything back together in reverse order of how you disassembled it and you’re done.
