Please note that the PICTURE UPLOAD function is not working. The iBoats Forum Moderators are working with the system administration folks at the parent company to get the issue resolved. This happened about a year ago and here we are again. In the meantime you can post photos as links to a picture hosting site of your choice. We are sorry about the inconvenience and will advise when the issue is resolved. Thank you for your patience.
It all depends on your "WOT" wide open throttle. What RPM you are running now. If the prop you have on the boat now is to big your WOT will be low. If the prop you have on the boat now is running in the manufactures RPM range there is very little you can do to get the top speed any higher except more HP..
