Occasionally the speedometer will work w/o issue but other times, the speedometer needle acts "sticky". Right now the boat is in my garage and the needle is showing 10mph. On the lake, sometimes when I accelerate to wide open throttle, the needle doesn't follow my speed and will either show much slower than i'm going or will creep up to my speed very slowly. What could be causing this? Also where is the speed sensor? I have a Mercruiser 4.3 alpha one.
