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

Now you know why marine mechanics get pretty high hourly rates... I'll be watching this thread but imagine all your replies (other than take it to a pro) will involve using a hot wrench (torch, hammer, drills, and a few choice words...).

And you are SURE you have all the bolts out? ie is there a bolt under the steering torque tab? I couldn't get my etec 50 lower unit off one time and I was SURE I had all the bolts out. Oops

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?

If it were me, I'd make 100% sure that the midsection is supported firmly (no give at all), and I'd work at it with a dead blow hammer. If that didn't work, I'd try to fashion a puller or screw jack of some sort.

Launch at the end of the road in Yankeetown, head North wide open, she'll be off in no time.

Kidding aside, I am watching this to try and learn something, good luck.

Sounds like fun. Nothing says lets party like a fist full of wood wedges and a can of degreaser. At least it's a 30 so you can turn it upside down if you need to. I've had success with strapping the lower unit to the legs of an engine hoist and pulling it apart.
