Perhaps a little correct knowledge is needed straight from a Merc V8 Manual prior creating panic and ordering a Evinrude!

Belt is a 300 hour item.

Please note that "Fly Wheel" replacements are not required!

Each 100 hour service is easy to do within an hour if the owner has 1/2 a brain and some tools.

Flatout is 100% correct. This is not a video of a 100 hour service. More interweb misinformation.

Having to roll a belt on is a terrible design. You should never remove sparkplugs and not replace them. The crush washer is only good for 1 use. By the time you remove and inspect the listed filters and thermostat wouldnt you just put a new one on?
