I have replaced both oil seals in my lower unit to fix an oil leak. The leak is fixed and I have reassemble everything back together. Now when I put the motor in forward gear (mercontrol single lever), the gear engages but I can't make it go faster (even at full throttle). If I put in in reverse there is no problem, it feels like the motor could climb up inside the boat.
What did I do wrong? Can anyone help me?
