I just bought a 18 ft sea ray with a late 70's 115hp jonhson on board. The power trim motor is shot acording to guy I bought the boat from. I've got quite a bit of work ahead of me, wiring especially, so I have not gotten a chance to test it myself.<br /> To get to the point, where can I get instructions for overhauling them, and are there rebuild kits out there for them, I can get the serial/part number if that would help, thanks.
