Review on 🔧 Mercruiser GM V8 Thunderbolt IV HEI Ignition Tune Up Kit - Replaces 187523, 805759Q3, 805759T3, 815407A2 - Distributor Cap, Rotor, Gasket by Christopher Gulledge

The cap did not fit properly on the distributor. I know there is a dowel pin on the lid that should line up with the notch on the manifold. The base of the cap appears to be a few thousand inches too small to properly fit on the dispenser. I didn't want to push it down with screws as the lid might break. This was my first trip of the year with the boat stored 500 miles from home. I've been a mechanic for over 40 years, but this isn't my first rodeo, Jim.
