Default TRS Rotation Questions

Silly question, but one worth asking . . .

I know Alpha drives are directional, therefore running twins you must have a counter rotating drive on the port side.

I know Bravo drives are bi-directional, and you can run them either way.

I cannot remember for the life of me if you can run a TRS drive in either direction, being that forward and reverse are dictated in the transmission.

I have one left hand TRS/SSM #2 remaining, and I have a gentleman from Australia who is searching for a RH rotation. Mine is a LH rotation.

Thanks!

Harry

And, sitting here reading my own post, I may have answered my own question . . .

Obviously if the transmission is put into forward, the drive is going to spin whichever way its forward rotation is, in this case, LH. But using a 72C, with a 1:1 ratio, couldn't you reverse rotation at the transmission, making forward into reverse, and vice versa, or am I missing something completely?!?

Please don't beat up on me too bad, I haven't had my morning coffee yet!

NO,,,,TRS have a LH and a RH drive,, u can't change it in the tranny.
The clutch plates will burn if running in reverse !!!!

Forward on a tranny is only forward and the rotation is switched in the drive ( lower) !!!!!!

Hope that helps !

The Bravo is the only one that works in either direction.

Thanks! That's really what I thought, but like I said, I hadn't had my coffee, and it was before 10AM, and . . . oh well you get my drift!

Do you know anyone looking for any TRS/SSM #2 stuff?

I have five transmissions on eBay and a LH SSM #2 listed right now, and I have a a pair of transom assemblies on the shelves, and some other stuff.

Here's the link: http://shop.ebay.com/merchant/southe..._mdoZQQ_sopZ12

Thanks,

Harry

The easiest way to tell if they are left or right is look at the end of prop shaft. They are marked L or R
