I have a 1997 yamaha 30 horsepower 3 cylinder outboard engine and it has started to play up,
When running down the river sounds like its missing and then it got that bad it was at full throttle and it couldn't get up on a plane,
I checked the spark and seems to be ok and when the engine was running i pulled off the top spark plug and it died and then tried the same thing with the second cylinder and it done nothing at all kept running like it was,
So i cleaned out the carbys and changed fuel hose and got new fuel and put in new spark plugs and still has the same problem,
I think it might be only running on 2 cylinders, The middle one might not be running, (Not Sure)
I am at a loss, Can anyone please give me any ideas of what may be causing this problem, Thanks.
