How deep are you going to be going under water? You need a gland for the shaft to pass through. The shaft needs to run true and not wobble in the gland. The gland needs to have a seal pressed into it which fits the shaft diameter and points the right direction to hold out water. (This similar to the seal that is used in places like the rear of your transmission of your auto to keep in transmission fluid). The gland needs to be water tight to the housing. I prefer to have two seals a short distance apart and place a lubrication between them during installation when using seals under water as water has very little lubrication quality. This keeps the seals "alive" longer. If you are going to extreme depths you may need more seals and or a packing gland. Extreme depths would be thousands of feet. The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
