Are there any good service manuals available out there for my motor? I'm replacing the engine block and adding a charging unit and want a good source that covers DETAILS, like cement type and torque settings, wire routing, etc.<br />Is there a Clymer that will be adequate if a Nissan factory manual is not available? What is the best source for manuals?<br />Thus is a great little motor, just right for my 25'sailboat, and I'm hoping the repair will put it in great shape. The water jacket was corroded to half it's stock thickness in one spot and I'm afraid to run it across the bar, into the ocean. Any thoughts?<br />Thanks
