Engine diagnostics report. Help please

This is pretty well in another language to me.  How does it look?  Why don’t the hours add up?

The information is for diagnostic purposes and are for the mechanic to look over for red flags. The individual numbers are not as important as what they mean in combination with each other. Think of it as an electrocardiogram the scribbles mean nothing as a scribble but by comparing and looking at all of them it tells you if things are meshing correctly. If there was any concern the mechanic would have been happy to explain how it was going to cost you more money.

You got out of a marine mechanics shop with a bill for $300, those numbers sound good to me. Don't  know about the hours!

I would guess they included the diagnostic data numbers stuff just to show off and to try and justify what they are charging the customer.

Maybe outboards that big are tougher, I've only done 3 small outboards, but I bet that mechanic could do the impeller in less than 20 minutes.
