The plate works great. Installation went well, although I wished they included shorter bolts (too) as they really stick out on a Tohatsu 30hp. It brings the idle speed down from 2.8mph to 0.8mph on an MFS30 with 14 pitch prop. By tilting up a little bit, and increasing idle a little, the boat is very stable from 1 to 1.5mph. However, anything above that is super wasteful in gas/noise and creates a ton of turbulence. I have seen other review mentionning adding another notch - I will be doing that, would make a lot of sense for the plate to come with this additional notch especially for the small engine one.
