Does any one know any products that will take the brown water marks off the bottom of a fiberglass hull. I have no anti-fouling on the bottom of the boat.
MarineEngine.com does not offer troubleshooting assistance or repair advice by email or by telephone.

You may also visit the Boat Motor Manuals section of our site to obtain a service manual.
If you got someone selling Star Brite products, they have some good stain and rust removers that are SAFE on fiberglass!
You can use a product called on/off. Its acid and you must wear gloves. Avoid the fumes. Its fairly expensive for what it is. Maybe 15 to 20 dollars at West Marine.
