Frequently Asked Questions
What is the difference between a 6-tooth and a 3-tooth clutch dog?
The number of teeth indicates the tooth structure of the engagement mechanism; selecting the wrong number of teeth will cause the shifting system to malfunction.
Can this part be used in a mid-section conversion kit?
Yes, it can also be used in conversion kits from a 3-tooth lower unit to a 6-tooth one.
