I have limited experience with marine engines, but considerable experience with vehicle internal combustion engines. I have a 2009 Mercury F25ELPT 4-stroke SN: OR299646 Manufactured Feb, 2009. The gearcase was disassembled to weld a broken skeg. This process was accomplished with a Miller TIG setup for aluminum. Before disassembly, everything worked fine. Upon reassembly the shift linkage moves properly, but I have no forward or reverse. I think the shift shaft isn't installed properly. Can anyone tell me the procedure for installing the shift shaft on this motor?
