Cheap price for the cable and terminal ends with heat shrink.
Size: 20FT Black & 20FT Red
Good 6 gauge wire, jacket seems sturdy and like it won't crack easily over time like some wire. Comes with all the connectors shown too so you don't need to find end ring connections to terminate the ends. Just need a punch or crimp tool for the terminals but if you already have that then just cut your wire length and add the ends for battery cable.

Outboard thermostat
Works fine. A little pricey but better to buy the best than risk a cheap failure and destroy your engine like i did once.
