Fit perfectly
Truly impressive, bought these and a set from a us boat supplier a thermostat made in the USA . They came with the gasket separate . I could not figure out how to put it together . I used these in my mercury optimax 135 hp . They fit perfectly and appear to be working great at a quarter the cost .

Good stuff!
Size: 5FT, Style: 8AWG
Good quality silicone insulated wire. It’s very flexible and solders really well. The silicone insulation can’t be beat for heat resistance. I will definitely purchase again.
