I will be cruising along at about 20mph, then suddenly it feels like I drop a cylinder...the engine slows down to about 10mph, and I compensate by more throttle to get back up to speed, then suddenly it goes back to where it was but now the throttle is much higher and I now have super high revs and have to back down to get back to normal. This could happen 2 or three times in a row, or not once in a whole day of boating. It is beginning to happen more often now. I have changed the plugs, new prop, new gas. Any ideas?
