Mercruiser Parts – Marine Exhaust System in a Carver boat with two 3.7 1989 4 cyl Mercruiser engines that have closed cooling systems. Do I ever need to replace the manifolds on these engines?
Gary,
Typically engines with closed cooling would have the manifold replaced every 15 – 20 years and the riser every 5 – 10 when used in salt water. Using the link below you can add your selected product(s) to your shopping cart and the shipping estimator located at the bottom of the shopping cart page will give you a shipping cost based on your specific postal code. Let me know if you need any further technical information or help placing your order. In either case I will be glad to assist!
