Tell me more About my New (to me) motor

[THEFERMANATOR]

I would double check the year as that one looks more like a 76 than an 86 to me. It has the old style switch box on the side of it, the 70's decals, and the mid 70's coils on it. They are good engines, but THIRSTY! Also that engine is maybe 150 at the prop if your lucky. The flat exhaust chested V6 cross flows later on became 150's, and the bubble backs became 175's when they went to propshaft ratings. And if your goign to use it in saltwater, you will need to add zincs to the engine. OMC didn't start putting zincs on until the 80's. I have an 80 and an 81 JOHNSON's outside, and neither one came with the 1st zinc on it from the factory.
