Default TRS gear ratio

Is the TRS gear ratio from a 1977 Scarab with SBC 350's 1.50 or 1.33?
Thanks,
Shawn

Back in the 80's I set up numerous TRS drives to a 1.32 ratio. Back then there wasn't big enough propellers for the engine hull combinations we had. Matter of fact today I am shipping out 1 of the tools to set up the lower TRS to a fellow OSO member to use. I will have to look at some old paper work to see how we did it.

Never heard of that being done before. That would be interesting to know how you did that.
