It needs to be run on the water, in gear, at the various RPM. In neutral, running it means nothing and I used to try justifying what I found when I would call MC and they (Mark at MC, Monty & Mark at Indmar) finally got me to understand this. It's a PITA to have to take it to the water, but if the weather is good and you have the tools, parts and time, it's not a bad way to spend some time on the water. Take your anchor and a long enough rope, in case you need to replace something away from shore.
