I assume the sst60 gearcase is still an illegal case to run in drags? Drags would interest me to run with our delta but have an sst60 lower


3 cylinder rules indicate "low water pickup, nose cone permitted" based on how written a sst60 would fit within rules "nose cone permitted", send them an email should be able to clarify


Mike and myself tried our SST60 gear case versus a borrowed nitro gearcase back to back with 4 different props on our critchfield. Each prop ran a different speed/rpm but the nitro case was 1 or 2 mph faster than the SST60 case with any of 4 props. Not sure of the results on other hulls but the SST60 case had no advantage on our critchfield.


Interesting that the nitro was quicker. What speeds did you see with each case? Best ive seen is 72.1 in our delta with the sst60 case, drives like a a dream

Yup nitro is quicker, the cone tends to pull the ass end when buried and at angle like a wedge

best we could get out of the sst60 case was right around 69-70. the nitro got us just over 71. Your setup sounds quicker than what we had. The sst60 case was fine on the lake but sucked on the race course. It was difficult to set the boat when you were in the slop. As long as you can run out front you won't have to worry about sloppy water. :lol:
