Well I finally got the chance to take out my repowered 640LX last night. I went from a 40 Force to a 90 Merc and saw quite an improvement in performance I borrowed a 22" Laser II to get an idea of which prop I should use. I was turning 5700 RPM but only going 44 MPH. I was expecting more speed. It seems a popular prop for my rig is a Power Tech but I don't know which one to order. According to my local prop dealer there are at least four different Power Tech props for a 90 Merc. I was thinking I should go to a 23" to cut down the RPMS and increase top speed. What model of Power Tech should I order specifically? I can get a Turbo off the shelf today if you think it's six of one and a half dozen of the other and not have to pay shipping. Pat Goff suggested the RXB blade on my previous post on this subject but I can't find that option on a three blade prop.
