Economical relay setup that would cost $$$ at a marine dealer ...

Pretty much work on any lower voltage DC motor that needs reversing directions ....

Good stuff! You can swap them when one goes out to get by. Good engineering if you think about it. I dropped in Dale Hollow for a two day tournament when the down relay just quit. Err. 10 minutes before blastoff. A local mechanic supporting the Tx told me to swap the relays to get gone and had another waiting on me at weighin. Good people.
