Poor quality
Size: PP67-712 V1
Poor quality. Replaced a starter solenoid on a mercruser 4.3. Right off install it would click but not make a connection to start motor. Confirmed this was the culprit by jumping the terminals. After testing multiple times found it worked a little less than half the time.

Buy them. You won't regret it.
Size: 10 FT, Style: 0 (1/0) AWG RED
Thick, flexible, quality cable. Overkill for what I've got but man they flex like wet noodles easy to run.
