Thanks for the info guys. My boat has the same setup as wake77's boat in the picture, so it's a submerged drive. I assume wake77's boat has a cable for the drive? Also, what is the ideal submersion of the prop on this kind of boat when at rest just floating in the water (i.e. how far below the surface of the water is ideal when doing the fore/aft balancing of the boat)? And finally then, the boats with the solid shaft and stuffing tube where the prop comes out the bottom of the hull at an angle is also submerged drive?

Now, this might be too broad of a subject but what are the advantages/disadvanteges of the submerged drive systems (the flex cable versus the solid shaft) and also what are the advantages and disadvantages of surface drive. If the prop on a surface drive is so far out of the water doesn't that reduce the thrust since the prop is churning air as well as water instead of just pushing water?

Thanks in advance.
