I have an issue with a bolt on one of the cylinder heads on one boat
engine I have. I need to swap cylinder heads on the boats, and the
donor boat is fighting me tooth and nail.

The problem is that 1 bolt will not come off. It's towards the bottom
of the engine (I had to take off part of the engine cover part) and no
matter what I do (vice grips, socket, soak it with liquid wrench)
nothing will budge this thing.

Any suggestions? I can provide pictures to better explain where the
bolt is.


Check out this very cool tool. It's saved me a few times over the years.
Home Depot might carry them, but good luck getting one of their idiots on
the phone to go check for you. Try tool specialty stores, plumbing supply
places, etc.

I just found out my dad has some of those, so I'll try to borrow his.


If access to the bolt is difficult (and when do problems occur in easy
places anyway?), you might want to practice a couple of times on one that's
more accessible. By the way, these tools are also great for removing stuck
valve seats in old style faucets, when the previous handyman has stripped
out the surfaces that the valve seat tool would normally grab.

I removed the part that was in the way of the lowest bolt (seen in the
picture I linked. I didn't remove it on this engine, as I was able to
get that bolt out easily.

Im sure I'll be able to figure something out, as thankfully I don't
need to "fix" this boat till next year (in the sense that I'm not
paying $$ to registure it for 4 months. I know in Oregon (atleast) you
pay for 2 years...and they don't pro-rate it.) So if it sits for a
while, I'll be ok with it. I'll just cover up the engines, and take out
my frustrations on something else.

To all those who provided some, thanks for the info.

I've got a whole set commonly called easy outs! But in his case it
sounds like it hasn't broken off flush, yet!


It may still work, though. If he drills deep enough into the bolt, most of
the turning force would be within the shaft, not the head of the bolt.

And what happens a lot is just the drilling into the shaft loosens the
bolt some from vibration. As someone else has posted here, it also
helps to heat the portion of metal that is surrounding the bolt.
Thermal expansion is your friend!

six sided 1/2 inch drive socket and a long breaker bar. Since it is a donor
anyway, what does it matter if you break the bolt?

tried that, and it just rounded over the bolt (and then I did more
rounding over with the vice grips, intermixed with four letter words).

Craftsman makes some sockets that are made to work on rounded bolts.
They are really nice. The more torque the tighter they grasp.

Provide a picture, please. And knowing what we are working with will
help too. Outboard?

sorry, I was in a bit of a rush when I wrote the first post.

it's on a 65 Evrinrude, outboard (75 horse). The pictures are of a 62
Johnson (same hp).

Here is the sockets from Craftsman that grip rounded off bolts:

I bought the Mickey Mouse 'Craftsman' version that Bob Vila flogs.
The one time I tried to use a bit... it was useless.

Don't confuse WD-40 or Liquid Wrench with PB Blaster. That stuff
works like nothing I have ever seen.

I'll second that. PB beats the others.

One other approach you might want to take, is to turn the engine on
it's side, put a wrench on the bolt and rig a 20 pound weight on one
end being very liberal with the PB Blaster.

Tap on the head of the bolt a few times with a hammer, apply the PB, rig up
the wrench/weight and wait a few hours. Repeat.

Give it about twelve hours and it will come free.

Yep, got some seriously frozen brake caliper bolts loose this way.

Otherwise, if you can remove the item with the bolt shaft still in the block
then drill or grind off the head of the bolt. That's assuming torque
doesn't snap it off anyway.

Nice series of positive contributions Kevin. Good advice! ;-)

I went out today, and bought some of the BP Blaster stuff. The guy at
GI Joes (the store I got it from) was very adiment that it was the best
stuff out there. So hopefully I'll have another bolt off tonite.

thanks again guys.

I have heard the same thing about PB Blaster.
