I am getting a GPS speedometer. At the speeds I will be traveling with the 88' 115 HP Merc, the pick-up tube will be kicking up out of the water, the boat will be airborne half the time, and the pick-up tube will be slowing me down a fraction of a MPH. All good reasons for getting a $500 GPS speedometer. LOL
The logo on the back of my boat: Either Own a Glastron V-153 or Follow One. LOL
