Fits 1988 Sea Ray V-135 2 stroke (Mercury)
For those of you with the 135 hp mercury that was branded as the "Sea Ray 135" and paint matched to the boat (i.e. Seville's and some others) this is the 147 degree thermostat for that motor. My Seville is an '88 and It's difficult to cross reference the serial numbers on those motors when searching for parts. Only buy Quicksilver parts for these motors. Happy to find them on Amazon because Boats.net as an example, is not clear on what you're getting.

Carries all the current I want. Super flexible, great price
Size: 8 AWG 3 ft per color, Color: Red and Black
Very nice high quality. Somebody tried to tell me this was aluminum strands. But after test sanding an exposed end, I could see copper color. I believe the confusion is they are individually tinned strands? 🤷 Just sayin...

Much easier to use over trying to put the hard case extension wires in my solar controllers.. very well made. Now I can feel confident I got the wires in properly.
