Gear ratio Alpha One

[cbavier]

Is there any way to tell what my Gear ratio is. I have a 1986 Alpha One but the numbers and ID have faded away. My owners manual lists two possibilities. 1.65.1 and 1.84.1 How can I tell which I have? I may have the serial numbers written down from years ago. I have tried to search online to no avail. Any help would be appreciated.

Ayuh,... Sure,... Mark the propshaft, put it in gear,+ bar over the motor 1 revolution....
Then look to see where the prop turned to...

Thanks Bondo O I just found it. 1.84.1 . It was stamped under the Mercrusier tag and barely visable. I had to get in the daylight just right to read it. I have looked on and off for a year and couldn't find it. The boat was sitting just right in the sun today. We haven't had many sunny days up here this year yet. Thanks again.
