Mark at Borel returned my phone call yesterday afternoon. I told him of my long favorable use of his product aboard my boat and the renewed interest in the pump run-on alarm.
He has retired and no longer manufactures his products. I told him there might be an expanded market for the product due to publication of its utility. He indicated he would not restart production. I further inquired if he would be willing to sell the production rights etc. and he expressed no interest in doing so.
Darn it, I guess we will have to look elsewhere for a 28 VDC pump run-on alarm.
