Nothing more family friendly than boating, hope you see you out there soon. Certainly some arguments in there for using manual pumps, but I do own boats with electrics as well. I'm using a carter pump simply cuz it said it was marine rated, and several of the pumps in the shop, Holley, Facet, did not. As for wiring, it's just tied to the ignition switch, powers on when key is on. I thought about safety relay's and such, but if the motor dies unexpectedly, I turn the key off anyway and investigate. My lanyard safety switch drops power to both ignition and pump since it's the same wire from helm.
