One other thing was the payment, which must be made in advance. We're talking a near $5000 order here, so that makes sense. I'll be out of town for awhile, so might ring Jon in on this. I've asked for specifics about shipping to see if the units can be drop shipped from the manufacturer or have to be routed through the dealer and then onward. Will let you know how that works out.

And speaking of motors, I just got off the phone with Master Repair and should be getting some information from them about our order either this afternoon or Monday morning. It would be helpful to know approximately how many motor/speed controllers we are interested in as a group. If we can order them at the same time, then the price break would extend to them, as well.

Karl's experience, and the rust we saw when he tore down and overhauled the propulsion system on Idabel, suggests long-term dampness in the system, but whether from moisture buildup from air charges on his HP air or from minor seepage is hard to tell. I wonder if the use of nitrogen in a stand alone compensation system would be worth a try. And a slow, end to end system flush after diving. With no oxygen left in the system, rust would be held at bay, and the flush might warn you of excess moisture. Beyond that, it's hard to deny his experience. His system works. The oil comp does, too, so it gets back down to a choice.
