How to Replace the Fuel Filter on a Yamaha SX230 Jet Boat

The SX230 is a jet boat manufactured by Yamaha that features twin 160 horsepower four-cylinder four-stroke MR-1 marine engines, room for 10 people on board and multiple storage compartments. If the SX230 stalls out or seems to be running rough, it may be because the fuel filters need to be changed. The SX230 fuel filters are inline filters that take from between one to two hours to change out.
