Although there were very good prices from all BBC sponsors on Power Pole Blades, I ultimately chose to go with Wacky Riggers. Thank you Roy for your outstanding customer service and quick turn-around.
The jackplate is a CMC Powerlift with 10" setback. I mounted the pumps in my starboard side rear compartment (my tools go there anyways). The relays came from a local auto-parts store and are 12VDC 40 Amp. The poles only come on when those relays are powered by my accessory switch.
