These fit 1989 to 2005 40/48/50 Johnson/ Evinrude. This gear set fits Johnson and Evinrude 40/48/and 50 hp 2 stroke motors. Gear Set Forward, Reverse Pinion Gear & Clutch Dog for Johnson Evinrude. So this is a case of actuly improved design over the oem.
Not only the product was excellent but, the support was super, I called to get a clarification, and Joe was real helpful, he even explained me how to install it and get correct clearance, nither to say I was able to install the gears and enjoy my boat on Father's da😁😁
