This part came off a Mercury 70hp but I'm sure it's used for others. "37896 GUIDE BLOCK, LINK " is what it was being sold as but everywhere I look they're all unavailable. My piece broke so I've made up a new one. I recommend printing this and then casting a mold to use a stronger material considering this is a part of the shift linkage. It would probably be fine at 100% infill but that is completely up to you.
