"I have a 1978 115hp merc outboard. When setting the timing belt on the distributer am I lining up the flywheel on TDC and then align the marks on the distributer with marks on the fly wheel, the Seloc book is kind of vauge.

Thanks Dan"
 
"The flywheel has 3 dots on it

"The flywheel has 3 dots on it ,but it also has a band on it that has TDC in the middle.This engin is running rough at idle and when i give it a little gas. I have replaced the plugs ,it has good compresion and seems to be getting gas. I have only run it in the yard and wanted to check this belt before i put it in the water.
Thanks Dan"
