Detent shifter, can't use because it is too close to the side on my boat when mounted, it would work just not so well in a panic situation.  It's used, was anodized blue originally but most of that is worn off and I tried to polish what was left off.  I painted the mounting plate the color you see it now.  Used so sold as is, $55.00 delivered to your door before it goes on Ebay.
