Recently purchased an '03 Outback LSV and have some questions on calibrating the speedos. It has a 320 HP engine and single paddlewheel pickup on the bottom of the hull. I've heard that at approx. 3000 RPM you should be doing roughly 30 MPH, but I don't know if that's accurate or not. I tried to get fancy and calibrate it using my friends handheld GPS, but my 4 year old son dontated it to the catfish on the bottom of Lake Casitas before I got it done. Live and learn! Bryan Raymond, or anybody, have any thoughts? Thanks in advance!
