Malibu Boats Prop Shaft 1-1/8 x 45-3/4" Borg Warner 4" Coupler

Malibu Boats Prop Shaft 1-1/8 x 45-3/4" Borg Warner 4" Coupler. When ordering a shaft we suggest you physically verify all measurements since the shafting can vary with different engine models. Different model engines create shaft length changes and coupler changes. If you are having trouble figuring out what the right shaft is for your boat please contact us with your HIN (Hull ID Number) and we would be happy to help.
