I put my 1987 375 First in the water two weeks ago and on our first cruise of the season I noticed water coming in from behind the shaft I'm assuming that it is the packing in the rudder post. My question to you folks is; can I fix this leak without hauling the boat? Until today I didn't know there was packing on the rudder post. I assumed it was just a Beneteau magical seal. Suggestions on a fix would be greatly appreciated. It dosen't leak at the slip which also makes me think it's the packing. thanks all
