i would have to pull it apart and have a look.. which i might be able to organise..

by the looks of it in freds pic he's making a mod50 sandwich plate out of a standard one.... i can tell you it works just like the factory one

so the nitro with the 1.86 ratio what are they worth?

Still waiting for the tooth count or pictures of the 2:1 gears.

Hey Race Guys, What Is The Speed Difference You Have Noticed Between The Standard 3/4 Inch Thicker Case, And The Nitro? This Is Assuming That The Correct Props Are Used On Each Since Gearing Is Different.

Also, One Guy Told Me That You Can Take An 1/8 Inch Off Of The Case By Using A Belt Sander And It Will Still Be Thick Enough For Lighter Craft.

Any Thoughts?

Any chance you have any SST 60 or nitro gear cases?

[Flyer]

Any chance you know of something like this for sale?

[filthy phill]

did anyone ever come up with the tooth count on the aussie motors to get the ratio ?

I cant see why there was not different gear ratios in the larger case, it could easy of been a 2=1 ratio.

What other gear cases came with the 15:28 ratio? Or were they specific to the 15" 75hp ss models ?
