Replacing Exhaust Hose in a Grand Banks

Replacing Exhaust Hose and Mufflers in an Eastbay or Grand Banks

Like most items in a boat, the exhaust hose has a limited life span. Even with Grand Banks quality materials and workmanship, this is a periodic service item that is very important. 
Exhaust Hose Repair

Insure the longevity of your exhaust system

Most Grand Banks exhaust hoses have a life span determined primarily by the hours in use and the temperatures that the engine has been run. Higher temperatures or running the engine dry until it overheats will drastically shorten the lifespan of your hose, not to mention the lifespan of the engine. We check impellers annually! We also use high quality exhaust hose, fiberglass exhaust hose bends, elbows with stainless steel crush rings, and high quality T-Bolt hose clamps (below, left) to ensure the longevity of our exhaust hose replacement. The most important Grand Banks and Eastbay exhaust system components that have to be used in installation and maintained are hard wall piping, soft wall piping, high-strength elbows, stainless steel crush rings, supports, T-bolt clamps, and silicone to hold the piping to fiberglass parts like elbows and mufflers.
The time varies from job to job on exhaust hose replacement time. In the photo below you can see that this exhaust muffler is installed behind a bulkhead with no access. We then need to cut a hole in the bulkhead and create a new door or panel to fit over the hole after replacement. This adds a lot of time to a job. exhaust2exhaust3
