So it looks like I lost the forward gear on my Yamaha 200AETO the other weekend. Had to go up the lake in reverse to get back to the launch ramp. I got a few funny looks as you might imagine but it beats paddling.

I was wondering how to determine the gear ratio for the lower unit on my engine. I have looked around but cannot find the tech specs online for this engine. The engine is a 1984 200AETO 2.6 liter. I pulled the lower unit and the shaft measures 20 inches. I think it is a 1.86 ratio but it looks like the lower unit may also have come in a 2.0 ratio as well.

Any help would be appreciated.

The 1.86 gear case will have a 14 and a 26 tooth gears.
