I put one on about a month ago and couldn’t find a good video for it. I watched the example install video on their website (which is I believe on an Evinrude, definitely not a yamaha but it at least explains how it works) and then just followed the printed directions- took a few hours and the most time consuming part for me was running, securing, and hiding the wires nicely. The only thing I would do differently would be to try not bend the push rod first- it tends to flex a lot at the bend then and does limit the upper throttle range of the trollmaster because of the flex.
