The speedometer on our 2011 RZ2 is broken. Getting nothing on the needle or the display. I assume this is a malfunctioning or broken paddlewheel. Going to try to get up and check this out when I can. Seems like an easy fix if it is just the paddle wheel, as I've already found the kit online, thanks to some other posters with similar issues. I would like to just convert to a GPS type of speed tracking, but it appears the Nautic Laugic product is no longer available. I've never had this issue before with the speedometer. I also just started using the dry docking service at a marina, instead of trailering every time. Hope that is just a coincidence.
