My speedometer stopped working on my MerCruiser 4.3 MPI 220 HP V-6 I/O. I am not sure if the connection came loose, but I am not sure were to look for it.
I have a new boat and wanted to be able to winterize it myself. The engine is a MerCruiser 4.3 MPI 220 HP V-6. The proper steps to complete this task would greatly be appreciated. I live in S.C. and the winters are fairly mild if that makes any difference
