Maintenance for Sea Ray 175 boat
Had everything needed for replacement of lower unit impeller. Should be replaced every 3 to 5 years.

Great quality wire for any automotive or 12 volt wiring
Size: 16 AWG-100 ft
This GS Power 16 gauge wire is excellent quality for any automotive wiring project. The copper is true OFC pure copper, not copper clad aluminum. It’s flexible, easy to route, and holds up well without the insulation feeling cheap or brittle.
I have used it for automotive accessory wiring and some 12V equipment projects and it handled everything perfectly. The wire pulls cleanly, solders well, and the insulation thickness gives it a durable feel without being overly bulky.
If you need dependable wire for automotive, marine, RV, audio, or general electrical projects, this is a great buy. I would absolutely purchase it again.
