Best looking shift knobs I've seen, and they have the 3/8 fine threads that fit my Malibu. <a href="http://www.flameball.com" target="_blank">www.flameball.com</a>

How would you make it light up? <BR> <BR>Are there power wires running up in the shift knob?

I'm actually not getting one of the ones that light up. There are instructions on how to wire them on the page, but it seems that those would be suited for cars than boats.

let me know if it works for you. i think my friend tried to do something similiar and the throttle on the boat had different kind of threads. it didnt fit. if these do fit your boat, i might need to get one
