I'm hoping that some one, in this great community, can help me find a repair manual. Or even a pdf file i can download somewhere. I have a '71 35hp Sea King Outbaord. It looks great and everything seems to spin right,manually. But I want to change the oil in the lower unit and all those basic maintenance that should be done. Since it's sat for so long I'm concerned about some of the seals and impeller might need replacing. And i'd like to do the work myself I'm kind of a DYI guy.
