3 or 6 jaw on lower unit?

[zzimmer3]

I'm looking at some reman lower units to replace mine on 1989 75 hp 3 cyl mariner. its asking if I have a 3 jaw or 6 jaw lower unit (i think they meant the clutch). how do I tell the difference? hope this isn't to stupid of a question. thanks.

Re: 3 or 6 jaw on lower unit?

If yours is original its a 3 jaw as the 6 jaw came out in 1998. You can tell 2 ways: (1) All OEm units taht are 6 jaw will have a 45? line machined just foward of the trim tab bolt (2) measure shift arm center to center.a 3 jaw will be 6 1/4 and straight and a 6 jaw will will have a hook in one end and measure 6 5/16. I always use the #2 method as the aftermarket replacement unit do have the machined line.
