Which company owns MAC address prefix C8:71:25?

MAC address prefix C8:71:25 is registered to Johnson Outdoors Marine Electronics d/b/a Minnkota in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C8:71:25 has a network interface built by Johnson Outdoors Marine Electronics d/b/a Minnkota.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C8:71:25:00:00:00 that is C8:71:25 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

How many MAC prefixes does Johnson Outdoors Marine Electronics d/b/a Minnkota own?

Johnson Outdoors Marine Electronics d/b/a Minnkota holds 3 OUI prefixes in the IEEE registry, of which C8:71:25 is one. A device made by Johnson Outdoors Marine Electronics d/b/a Minnkota could carry a MAC address from any of them.
