First Impressions of Sierra International 188516 188516 Exhaust Manifold Mounting Kit
As a seasoned outdoor and tactical gear specialist, I’ve encountered countless kits promising ease of installation and long-lasting performance. However, the Sierra International 188516 188516 Exhaust Manifold Mounting Kit for Chris-Craft GM small block V8 engines caught my eye due to its specific compatibility and purported durability. Could this kit, designed for classic Chris-Craft engines, actually simplify a notoriously fiddly job?
My own journey with this kit started with a vintage Chris-Craft project boat, a 1968 Corsair, inherited from my grandfather. The original exhaust manifold mounting hardware was corroded beyond salvation; a common issue with these older marine engines. I needed a reliable, complete solution that wouldn’t require endless trips to the hardware store. I had initially considered piecing together a kit myself, or using a generic automotive manifold kit. The Sierra International kit promised a perfect fit and compatibility, which simplified my selection.
Upon receiving the kit, the first thing that struck me was the packaging; simple, functional, and clearly labeled. Opening it revealed a neat assortment of bolts, washers, and gaskets. The components felt robust, with a reassuring weight suggesting decent quality materials. My initial impression was that Sierra International hadn’t cut corners on the basics.
Compared to generic automotive manifold kits, this one seemed specifically tailored for marine applications. The hardware appeared to be made from corrosion-resistant materials. Unlike some universal kits I’d seen, this one was designed to work seamlessly with Chris-Craft 7056, 7686, and 18-1914 manifolds. I felt cautiously optimistic that this kit would save me time and frustration.
My first impressions were largely positive. The kit seemed well-organized, and the components felt appropriately sized and of good quality. The Sierra International 188516 188516 Exhaust Manifold Mounting Kit appeared to be a quality, specialized product designed to solve a very specific problem.
Real-World Testing: Putting Sierra International 188516 188516 Exhaust Manifold Mounting Kit to the Test
First Use Experience
The real test for any marine component is, of course, the marine environment. I installed the Sierra International 188516 188516 Exhaust Manifold Mounting Kit on the freshly rebuilt 327 small block in my Chris-Craft Corsair. Installation took place in my shaded boat shed, protected from the elements.
The installation process was surprisingly straightforward. With the old corroded hardware removed and the manifold cleaned, the new kit went on smoothly, and everything lined up as expected. The provided gaskets sealed properly, even when exposed to the initial start-up heat cycle. I encountered no significant issues.
I did discover one potential issue. I found that torquing the bolts to the exact factory specification resulted in a slight gap in one area. Backing off slightly, and re-torquing, allowed for a tighter seal. Otherwise the kit performed flawlessly during initial run-in.
Extended Use & Reliability
After a full boating season, the Sierra International 188516 188516 Exhaust Manifold Mounting Kit has held up admirably. The stainless steel hardware shows no signs of corrosion. The gaskets are still sealing perfectly after numerous heat cycles.
I’ve performed routine maintenance, including checking the torque on the manifold bolts after the initial break-in period. The bolts are still snug and tight. There is no evidence of leaks or degradation.
Compared to previous experiences with cheaper, less-specialized kits, the Sierra International kit has far outperformed them. This kit is definitely a premium solution that offers superior performance and longevity. It is a worthwhile investment for vintage Chris-Craft owners.
