Imco lower gears 1.50:1

are the Imco lower gears the same as merc xr gears?
I have a imco with 1.34 gears and looking to change over to 1.50 gears.

I think they are a little diff. in the style but should still fit.
But why would you do that on a cat ??????
You got accselaration anyways ,you gona lose top end about 4-8 MPH unless you reprop and dial everything in new.:cool-smiley-011:

If you are referring to an Imco SC lower, the gears are the same as a Mercury XR set. No difference at all.

I have a 31P B1 labbed and a 32P B1 std. one of these will probably work with the 1.50's
