Does not fit Spare Parts

Fits Mercruiser 5.0 with Thunderbolt IV Ignition. It didn't fit well. It was very tight and I had to tap it and use screws to pull it to the manifold. Also, the supplied screws had the wrong thread pitch, which struck me as extremely odd. I reused old screws. All said and done, it works as expected.

Pros
