Before you go cutting with a sawzall, I would get a GOOD 1/4" die grinder and a carbide bit and go in and relieve the housing around the broken bolts. You should be able to use a 2" long cutting bit and go in there and remove some of the aluminum and relieve some of the pressure locking those bolts in there. It looks like your going to have to replace the adapter anyways, so at this point why not just cut her up and make less work for yourself.

If the bolt heads are accessible, why not grind them away
and then dissassemble the unit and then work the bolts out?

the shanks of the bolts are sticking in the mid plate.

I believe they have already broken off. That is why he drilled through them to cut the bolts in half up higher.

Ferm, you are a real man of genius. Got some carbide burs at work...

They have 4" long shanks which lets me get real close to the block...

I think I'll try to grind right through the bolts and leave about 1/2" to grab onto when I remove the stubs from the block. And yeah, the adapter is going to be pretty chewed up by the time I'm done and I will need to replace it. At this point I'd go the sawzall route if I was sure that I wasn't going to cause damage to other parts. The controlled demolition with the bur seems like a safer choice.

For those of you tuning in late, three of six long bolts that hold the powerhead on are sheared at the head. The problem is about 6 inches of the shank is frozen in the adapter plate by corrosion, pinning the block to it.

not to throw a wrench in but have you checked for a new adapter plate yet? i need one for my 92 Johnson 225 and no longer avail. plus the cost new was like $600+ so it's not worth it. :head:

The part and price you need can be found at boats.net. (Central Florida Yamaha) URL below. I have bought alot of parts from them and I find their services, prices, to be very good.
Their prices seem to be considerably less than purchasing from my local Yamaha dealer in PA, or NJ. You may want to check in with Ebay or Boat Recyclers of Wilmington to get a used part. I have the URL's for about 6 or 7 more outboard junkyards on the east coast. Let me know if you need them.

i looked at that link Geekie1 posted first and no midsection parts listed there, good luck hope you can find one, like i say never found one for mine. but mine was a Evinrude or Johnson 225.

I think he already has the part, looks like he got it from BS.
