Where I'm at right now is a 10" diameter pipe with hemispheres on each end, the hemisphere with the motor shaft coming thru will be welded on but the other one will basically be like a small hatch with an o ring on the hemisphere side. And instead of a hinge I'll have a bolt in the center ( with o ring) to secure it down. I guess I'll need to have some sort of finish ( like stainless) where the hemi "hatch" mates to the pipe, and machine a o ring groove. I will have to add some small flange to those edges since the pipe is only .365 thick. I would like the option of either having the pod oil filled or dry . For all the Kittridge folks out there, is this basically how your motor pods are sealed?</div><div> </div><div> Thanks, Brian</div></div>
