My first impression was one of cautious optimism; I hoped this kit would deliver on its promises.
Real-World Testing: Putting Sierra International 1852871 Hi Performance Conversion Kit For Prestolite 6 Cylinder Distributors to the Test
First Use Experience
The first real test came during installation on my Chris-Craft’s inline-six. The installation process was straightforward, thanks to the well-written instructions. The conversion kit fit perfectly into the existing Prestolite distributor housing.
During initial startup, the engine immediately exhibited a smoother idle and a more responsive throttle. After adjusting the timing to the manufacturer’s specifications, I took the boat out on the lake. The engine ran noticeably stronger, especially in the mid-range RPMs where it previously struggled. There were no initial issues and the upgrade seemed promising.
Extended Use & Reliability
After several weeks of use, the Sierra International 1852871 Hi Performance Conversion Kit For Prestolite 6 Cylinder Distributors has proven to be a reliable upgrade. The engine starts quickly, idles smoothly, and pulls strongly throughout the RPM range. I’ve logged about 50 hours on the engine since installing the kit.
The kit shows no signs of wear and tear, and the wiring connections remain secure. The Sierra International conversion kit requires minimal maintenance. I periodically check the wiring connections, but no other attention has been needed.
Compared to my previous experience with points-based ignition, the electronic conversion kit has been a significant improvement. The engine performance is much more consistent, and I no longer have to worry about the hassle of adjusting points. It outperforms any points-based setup I’ve used in the past.
