Where to find manual for 1987 suzuki j6001 marine inboard motor?

The manuals that are going to be the most help are the Suzuki Outboard Service Manual for DT-60W (premix) to cover the power head, or the Clymer Pro Series Personal Water Vehicle Service Manual (in the Funjet section) for more general questions. Both manuals are easily found for purchase on Amazon or e-Bay.
