Johson and Evinrude 9.9 and 15 hp models from 1974 thru '85 use both gears; 1986 thru '92 models only use the vertical gear and its pin. This deal should be cheap enough to satisfy either requirement. Shipping is reasonable via fast and tracked USPS First Class Parcel.  Thanks for looking. 

Note on price: I'm throwing this up today without doing a price check on comp's; if you need the part[s]and there's a better deal on the board shoot me a msg / offer.
