i have a 2002 150hp ox66 model yamaha it has recently developed an issue when i run for awhile it feels like it deveoped a miss and when i ideal around and try to throttle up again it serges bad. if i shut the motor off and count to 20 and start it back up it runs fine for a while. i pulled the plugs and noticed oil on them. it just started recently using more fuel and oil than normal. does anyone have any suggestions to resolve these issues.
