Overview
The H3R Performance MX250C is a 2.5 lb. MaxOut chrome dry chemical fire extinguisher, part number MX250C, rated 1A:10B:C by Underwriters Laboratories. Its fitment is universal, so it is not tied to a particular year, make or model. It is US Coast Guard approved, with the bracket listed on the UL label.
The MX250C uses a specially fluidized and siliconized mono ammonium phosphate dry chemical. MaxOut models MX250C, MX250B and MX250R are effective on common combustibles such as wood and paper, along with flammable liquids and pressurized gases. The unit is well suited to marine or residential use.

Mounting for marine use
For a boat, the mounting location should keep the extinguisher within easy reach from the helm or cabin entrance, and out of the path of stored gear. Consider how the unit will move in rough water, and make sure the bracket holds it firmly without relying on the handle. Check that the handle can be gripped with gloves on, since wet hands and cold conditions are common on the water.
Salt spray and humidity slowly wear down fasteners and finishes. Wipe the body after exposure, check the bracket and screws for corrosion on a regular schedule, and replace any hardware that has weakened. Dry chemical units also need recharging after use, so plan to service the unit before it returns to its mount.
