I just bought a 1984 Century DayCruiser which is what it says on the title but after much looking around, the closest that i can find to the model of the boat is it a Century SunExpress 5000. The problem is that i still can not find any info on this boat as to what type a stern drive gear ratio. It has a 228 Mercruiser Motor and a Mercruiser Stern Drive. Also looking for a wiring diagram for the whole boat as it was rewired for some unknown reason. Any help would be appreiated
