If you had difficulty starting the engine, lost engine power, or experienced decreased acceleration, your boat's spark plugs may be failing or in poor condition. Invest in a high-quality spark plug to improve the performance of your boat. The BPR7HS-10 SPARK PLUG (86-1092) is a trivalent metal plating that provides superior anti-corrosion and anti-seizing properties. It is designed to operate over a much broader heat range than ordinary plugs. It can resist carbon buildup and pre-ignition. The BPR7HS-10 SPARK PLUG (86-1092) is made of high alumina ceramics for better heat transfer and electrical insulation. Its solid copper core and nickel tipped electrode provide a longer plus life to the spark plug. This spark plug is patented with a triple gasket sealing process that eliminates the possibility of combustion gas leakage.
