"If it is something you want to do yourself, start by purchasing an OEM OMC Service Manual for the Year Model Drive you have. With that you have enough information to remove the Outdrive and then the Upper Gearcaee. From there, unless you have special tools which are noted in the Manual, you will need to find someone that actually works on OMC Stringer Drives and have it resealed. Then put the drive back together and bolt back onto the boat. FYI, Assuming no actual damage to the Gearcase or anything related an Upper Gearcase Kit is all that should be needed."

"Two main components. Upper Gearcase and Lower Gearcase. Upper Gearcase basically connects to the Intermediate Gearcase that is attached to the Engine. Lower Gearcase mounts under the Upper Gearcase. Upper has gear Ratios that correspond to the size of engine you have. The Lower Gearcase is what the Propeller is connected to. Hope this helps.
