Outboard is Cooling
The repair kit arrived on time as scheduled. The kit contained everything needed to replace the Mercury 175 OptiMax impeller. The engine is cooling now and we are back on the water without issue. Easy replacement.

Flexible PVC Cable
Size: 2 Gauge 10FT
If you like the slick, shiny surface of PVC but want the flexibility of welding cable, this is a pretty good option. Easy to shape and makes solid crimps. One of my favorites.

Good quality for a good price!

Good value for the quality of these copper cables. Cut them to the length I needed and put a copper eyelet on one end. Wire size works good between my Victron solar charge controller and the batteries. Wire gauge will be able to handle the wattage much better than what I was using. They look much more professional than the old cables I was using also!

Be safe and always calculate the gauge wire are you need, don’t cut corners.
Size: 4 Gauge 10FT
Good quality solid copper 4 Gauge wires in red and black. Avoid aluminum wiring that has copper plating so looks like solid copper but can be dangerous if used in heavy load applications. Copper is expensive but required if amperage is high.
