1994 speedometer calibration Printed From: CorrectCraftFan.com Category: Repairs and Maintenance Forum Name: Boat Maintenance Forum Discription: Discuss maintenance of your Correct Craft URL: http://www.CorrectCraftFan.com/forum/forum_posts.asp?TID=50941 Printed Date: May-05-2024 at 5:51pm Topic: 1994 speedometer calibration Posted By: Tomrupp Subject: 1994 speedometer calibration Date Posted: October-10-2022 at 9:01am I just learned to calibrate with the bottom dial on each speedometer. I’ve been using gps speedometer in my smartphone since the factory speedometers were slow and out of synch. Most of you already know this move, but I did not. We just pulled and winterized yesterday. I had my gps smartphone app running while taking the last laps of the year. It was one of those, I wonder what this dial does moments. I’m totally willing to share this embarrassing miss on my part (for 6 years) if it helps one CC fan to dial in their speedometers. No obligation to admit if you were also unaware of this feature. Good boating to you with accurate speed. ------------- Tom 94 Ski Nautique Open Bow 351 with Carb 95 Double Decker Aqua Patio with 50hp Honda (3 carbs).
