Crusader R029015 Exhaust Elbow Explained
Crusader started using their water-cooled 4-inch center rise exhaust elbow on all of their V8 engines in 1992.
There is a lifespan for this item. These elbows and the exhaust manifolds are constructed of water-cooled, water-jacketed cast iron. Depending on its use and maintenance, cast iron exhaust will only last 4-6 years in a saltwater environment. The exhaust parts of the boat will last longer if the owner flushes the engine with fresh water. The most determining factor for how quickly a product deteriorates is saltwater. Salt damages the product, causing it to clog up or rust through and perhaps harming the engine.
How to Protect Your Crusader Exhaust Elbow
The boat does drain some water when it is at rest. The ideal form of maintenance is to flush the engine with fresh water while at the dock. You might also use Volvo Penta's NeutraSalt to cleanse your engine at the end of the day. When engaged, NeutraSalt drains salt deposits through a tiny reservoir on the boat. As you are coasting into the dock, you press a button. This enables the fluid to reach the cooling system where it will neutralize the saltwater and stop corrosion.
Once a boat part fails, it's obviously too late to repair it. When possible we've provided tips on simple ways to maintain a part to cut your cash outlay. We know you'd rather be on the water having fun than on the dock calling your marine mechanic.
