Hey all i have a 1988 scarab with bravo 1 drives, I blew the upper gears out on the port side drive and i am wondering what gear ratio it is and how can you tell what it is? Thanks for any help!

I would guess a 1.50 ratio. If the drives are close to originals like my old 1990 i had, it would be 1.5. Right down the serial number off the upper unit and take to a local merc shop. they should be able to tell u. Mine had 454 mags and spun 25 ptch mirages and run about 68. Hopefully this helps

OK thanks! 68? im guessing ur motors werent stock?

The decal on the l/h side of the upper usually
has the ratio stamped on it.

Otherwise, you have to know the tooth count of the upper
gear set.

if it's a 27 tooth pinion and a 32 tooth drivens, it's a 1.5:1

Ok great!! thanks for the help!

Here is a link to a chart of gear ratios.
