Mercury's website states that the R drive skegs are canted in the opposite direction from propeller rotation. Why wouldn't they do that for all of their models?

...the cle's have always been offered, this new gearcase, as well as all the older cle's, in either cant you want, or no cant at all. depends on the application & number of engines, etc. the cle's have always been out of racing/hi-performance division only. they are surfacing applications, other engines are not...

Are the cant angles cast in or formed (hot or cold)?

...what design should they have gone with, that you have tested, when you worked at mercury?...

With all that diameter to work with, what 5 1/2 gearcase, maybe a Bravo derived cone clutch? Just sayin'.

**FUJIMO** · 10-08-2023, 08:26 PM

...that route would be more durable, servicable & cost effective?...

The cones didn't last in bravos at 5K with 3 blade propellers grabbing on re-entry, why would anyone expect them to live at 6500 with larger diameter 5 blades grabbing more violently and harder on today's supercharged outboards. I have no issue with the DTS system, its very simple and smooth to operate from a drivers aspect. I hope they continue to improve the actuators.

...very familiar with all the bravo drives, since they're inception in '86. was looking for something that bernie bergen might enlighten us on, that maybe we didn't know about, from engineering...
