Can anyone give me a rough breakdown on how to change the timing belt?
Mercury 115 Direct Charge
And not sure the year of this engine Serial # 6560150 (Thinking its a 84)
Thanks Mike
If you are talking about the belt that drives the distributor then the newest it can be is a 1978. Is the belt currently broken? Do you have a new one? If not then leave it be.

The Timing belt is broke.
Bought a new one to replace
Well in that case by all means replace it. When you remove the top plate of the distributor pulley (remove the bolt in the center) you will see a dot on the gear. This dot lines up with dots on the flywheel, or just to one side of them in some cases. You will have to remove the flywheel in order to put the belt over the crank pulley, then re install the flywheel so that you can match up the marks. Most manuals have a decent picture showing this, even the aftermarket ones like Seloc. I strongly suggest that you purchase one, a picture is definitely worth 1000 words for this job. Its not a difficult job.

Mike, Set the flywheel to TDC. Remove the eight 5/16-24 bolts around the flywheel nut. I still think you will need to remove the inner flywheel, to get the timing belt to go onto the pully, due to the belt guard cast into the top of the block.

I agree Chris, the complete flywheel has to come off.
