On my 1987 Evinrude 140 I am trying to find out my gear ratio, but cannot find it in either manuals I have.

Anyone know what it may be or am I looking in the wrong places?

Re: Gear Ratio

The 13 spline gearcases are 13:26 or .50.
The 15 spline (TX, CX) gearcases are 12:27 or .44.

They are listed in the specifications sheets in the the owner's manual and in the factory service manual.

Re: Gear Ratio

Thanks Ezeke, poor research on my part. Didn't think to look in front of service manual, just went to gearcase section. Won't forget that section again (senior moment) !!!
