i am helping a friend redo the above boat. the name may be off but it is a twin 4.3 wiht Mercruiser Alpha one drives. i think it is a DA or maybe an express cruise. it is 26 ft 9 inches wiht a 9 1/2 ft beam. i have written to Sea Ray for the wiring diagram but they say it is too old and proprietary. can anyone help with this? we are ready to put the engines back in the boat but would like to check out the wiring first. once the engines are in, it gets quite cramped down there. thanks
