Looks good for ignition parts

I bought two, two engines. No issues so far, straight on the plane and 5500rpm which is about right for my 5.7 liter engines.

Pros
  • Sample for a year
Cons
  • Long delivery time

Poorly made threaded bolt/post. Problematic

I just bought an ignition coil for my Mercruiser and when I tried to fit and screw in the second threaded stud by hand, the stud was so soft that it sheared off with the same number of turns and force as the ignition coil . had a positive pole. Anyway, it's not something you want to press too hard, but the lock washer didn't even shrink before breaking off. When tightening, beware of very bad metal. Now I don't have the money for a $90 reel I can't use and a boat. I hope the seller doesโ€ฆ

Pros
  • Excellent overall performance
Cons
  • Clean

Properly dyno tested but very soft standpipe metal that cuts with little to no stress

So coil stand tested correctly and fits my 4.3 liter Mercruiser motor perfectly. The other parts made did not match the correct motor winding resistance values which should be 0.6-0.8 ohms for the secondary and 9.5-11.5 ohms for the secondary and the boat worked perfectly. I've used others on the Revain and the specs were either all over the place or 1.5+ ohms and that's no good and your motor isn't running properly and I had to return them. My biggest issue is the bar that the wires attach toโ€ฆ

Pros
  • Sleek design
Cons
  • Defects present
