Yamaha 30 horse lower unit issues

771 Views 8 Replies 8 Participants Last post by  jmrodandgun
I was given a 93 2 stroke Yamaha 30 horse buy my father’s boss a while back. The motor came off his dinghy that he used as a tender and has MAYBE 50 hours. Being as it has sat for the last 12+ years, I decided to go ahead and replace the obvious: plugs, fuel filter, water pump, etc.

When I went to drop the lower unit, I could see that it had never been done before and that someone had tried (hairline crack on the cavitation plate and a bend on the other side from hammering). Does anyone have any tips or tactics for removing a lower unit that is positively stuck? Thanks

I’ve got everything loose. What happens a lot is the shaft gets stuck due to sitting and once you can drop the lower unit even a 1/4”, you can pry things apart. Just trying to figure out the best way to get it started without further damaging the lower unit
rubber mallet?
