Great Tough Wire
Best option available to run power to your trolling motor. Best guage and very tough shielding.

High quality speaker wire for outdoor use
I bought a large spool of this wire when my two story deck and patio was being built. I wanted high quality outdoor speakers and cable that was also high quality. The install went great, the deck is 95% finished and the speakers sound fantastic. The person who built my deck said that this is the cable he’s using on higher quality build outs. It may not be the cheapest, but when you are internally running wire you may not see again for 25+ years… this is the way to go

Bulk Marine 12GA Wire
Wire seems good and is marine application rated, so I'm assuming its robust and will last. Shipping was timely. I would recommend this merchant.

Le cable est parfait, j’ai un bateau de 23 pieds avec 4 haut-parleurs et j’ai manqué de fils cepwndant avec 50 pieds. Je vous conseille 100 pieds pour un bateau de cette taille. Le fil se passe bien, il est robuste et juste assez flexible
