Looking at the cutaway in this link, I assume this a RH drive.

How is a LH lower different? Are the 2 gears on the propshaft set inbetween the 2 vertical shafts? Doesn't appear to be enough room.



Other question is how do #6's stay cool spinning huge power and high RPM's, with nothing but the skeg in the water?

Bravos at least have some internal water, the bullet is in the water, and some add drive showers. #6 has none of these.

#6 will go either way,,thet have straight cut gears,,its trs & ssm # 2,3,4,5 and the a's that are directional..

Yes, the propshaft gear is in between on the older drives. It is a short double sided gear. The newer drives change the rotation in the upper by putting the driven gear at the top or the bottom of the housing.

To turn that drive into a (L) you need to flip the driven gear in the upper also the way you set up the lower unit is unique from Rh to Lh.
