Gen 1 & Gen 2 ID ...

Basic ratio/engine matches:
Four cylinder engines used a drive with a 2 to 1 (1.98:1 & 1.94:1) ratios
The in-line 6 Mercruiser engines used a 1.65:1 & 1.62:1 ratio
The Merercruiser 3.7 liter 4 cylinder and V6 engines used a 1.84:1 & 1.81:1 ratios
The V8's used the 1.50:1 & 1.47:1 ratios.

The reason there are two ratios listed is because there was a change in lower unit gears so the ratios above are old ratio vs. new ratio.
