Re: speed is this correct

You are probably not getting even close to 50mph. Pitot and paddlewheel speedos are very unreliable over about 30.

If you want an accurate reading, get or borrow a GPS.

Re: speed is this correct

Thanks for the reply.The spedo is a brand new teleflex is there a way to hook it up different then pitot tube? I would like to use it and it be accurate. the paddle wheel is new also.I thought 50 sounded to fast. but felt like I was moving pretty good. And both readings are so close to each other but wasnt sure. Thanks for your time
