Mercury Kiekhaefer Outboard Wizard NOS 19 Tooth 43-24438 WD3 Twin Gear Forward Intermediate Housing Cupped Found on Mercury 800Item Description Mercury Part Number 43 24438 Forward Gear for Wizard WD4 (and some other twin cylinder outboards from this time period) I don't have concrete resources on this so please correct me if I am wrong!) I know 43 24437 was a 22 tooth gear that was for single cylinder WD3 applications that looks significantly different than this one. SO IDEALLY I would count your teeth on your current gear before ordering. Purchase with confidence! General
