1975 Wellcraft CC Inboard Question

[#LHB#]

I have a 1975 wellcraft inboard cc that was my grandfathers. I cant find any info on this kind of boat i would love to fix it up because it was my grandads but im not going to put 10k into a 5k boat i would love some info on this. I know the hull is in good shape and i would pull the motor and rebuild it and the out drive plus the gas tank and all controls i would love any input thanks. IF not could any one point me in the right direction?
