I heard all you have to do is a cable swap to reverse a bravo 1 any pics on doing this ? thanks Rob

Done at the shifter. Many shifters are set up to do this easily.

As an example, click on this link and you can clearly see how one of Livorsi's shifters is set up for this:
See page three at: http://www.livorsi.com/pdf/th_series.pdf

You can see how the cable movement will be reversed just by changing sides of where cable is attached.

you do also need to change the prop...

If you want to see if you like it before swapping the cable, just put the LH prop on there and test it that way. Just be careful around the dock!

yes, wanted to try a LH, which I did, our 253 did not like the LH as far as rolling over to starboard....
