I have a mariner 90 hp outboard motor. From idle to half throttle it seems fine but any faster it has a lot of vibration. I changed props and it helped a little but not much. If one cylinder was missing could that cause the vibration? |

Hi Darrel,could also be the prop shaft bent.turn it slowly by hand[on land]and see if the centre of the shaft stays still[or doesnt form a circle].Does the motor vibrate in nuetral? |
