 Gtr gearing Does anyone know the top and bottom tooth count of a gen three gtr with the old non-cast lower unit.
Thanks in advance I'm just trying to be lazy and not have to take my lower off and count.

Re: Gtr gearing 2011-2012 ish is when the 48 came out.
measure your top of belt housing to center of the side plate holes.
3" = 45T
3.375" = 48T
Also 48's were stamped 48T on the port side of the belt housing at the top.

Re: Gtr gearing Seems like Hotsauce got some good information, so I'm going to highjack the thread some.
Any input on preferred gearing for the 23/25 horse engines? Does anyone know what they are sending out the 25 Subaru’s with now?
I bought a used frame. It’s a 2013 and originally had a 35 Briggs on it. I bought the proper adapters/shims and put the 25 Subaru on it. I’m just curious if I could look at the gearing for a performance increase if there is something better for the 25.
