Just buy OEM, not imported scrap

Do not order. The screws are the wrong size and will damage your manifold. I tried to slow down but none of the screws were screwed in. Good thing I had a tap to re-tighten the holes that damaged the screws and used the original screws from my old cap. Just spend a few euros more and buy original parts. CHEAP IMPORT REFUSE

Pros
  • Cover and rotor kit
Cons
  • unreliable

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.

Distributor cap did not fit the distributor

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.

Pros
  • Automotive
Cons
  • Vulgarity
