86 Evinrude 300 xp lower unit is leaking gear oil from around

Customer Question

86 Evinrude 300 xp lower unit is leaking gear oil from around the o rings on the prop shaft bearing carrier. Manual says remove the two retaing screws and retainers and use a puller on the cross webs in the casting to pull out the carrier. I put a lot of pressure on the cross webs and its not budgging. I'm affraid its going to break the casting. My concern is that it looks like it might be threaded into the lower unit. Could the manual be wrong . Thanks, ***** *****

Hi Carl, my name is Jason.
The manual is correct. The problem you are having is the carrier is corroded into the housing of the lower unit on the inside. The only real way to get that out is first drain the oil. And then you have to head the sides of the lower unit with an oxy/acetylene torch until both sides are glowing red hot. Let it cool just enough for the red to go away, and then start pulling it. By heating the lower unit that expands the lower unit by 1/2 to 1mm, just enough to give the carrier enough room to pull past the corrosion.
Does that all make sense? If yes, did you have any further questions on the issue?

If you do have a problem, or if you can not see the ratings box which is at the top of the screen.
