“the engine is six years old and has 800 hours on it… this is the first time I have removed the riser elbows and was shocked at how clean they are…”

I just wanted to send a quick note to let you know how well your product has worked in my boat. I have flushed my engine with Salt-Away since I purchased the boat new in 2000. It is a Mercruiser direct drive engine that although freshwater cooled the risers and manifolds are not in the coolant loop. Just raw water through them. I am enclosing a few pictures, one of the risers and the other of a manifold. This engine is 6 years old and has 800 hours on it.

This is the first time I have removed the riser elbows and was shocked at how clean they are. No rust or clogs, just a little surface build-up which was easily cleaned. The boat shop I brought them to and who checked them was also surprised at how well they have held up. I had anticipated having to change both the risers and manifolds but ended up only needing new gaskets to reinstall them. I will recommend your product to all my boating friends. It will save any boater money in the long run.

Thanks for the great product.
