"My 2002 yamaha 150 2-stroke started running rough at wot, the only way to keep it running was to choke. Tried amsoil carb cleaner and seafoam, changed plugs, replaced bulb and fuel line. boat would run great for 3 miles then start the same. Finally dropped a cylinder, changed plugs ran good then lost 1000 Rpm and 7mph top end, firing on all 6, sounds oK but some loss of power throughout throttle."
