Top Speed??

Hi all. This is my first post on the site. I finally have my 89 v-20 cuddy running well and looking good. Will post pics if I can figure out how to use my camera.. I have a 89 johnson 200 looper, and I get about 40mph at 5200. Am currently playing with a new Pro-Pulse adjustable prop to see if I can improve on that. This is a great site.
