OEM Equipment for the following engine models (and the boat that we are aware used these engines... There could be other combinations as well):

• M-2-12 (Catalina 25, Capri 26)

• Inside diameter: 7/8"
• Length: 9-1/2"

The length of this item is based on the original factory specifications. However, the previous owner, like Captain Jack Sparrow, may have had an entirely different idea about how to rig a boat! Please confirm this is the correct length for your particular boat. We cut it from a long length and can't splice it back together again. Your order cannot be canceled, returned or exchanged, but, like Jack, you may have a different idea of what you can use it for!300816
