Are you sure it is 5/16? The replacement bolts have been 3/8 for the last 15

shot to see if it fits.

Trying to replace trim tab on mercruiser outdrive.
5/16 bolt stripped by last owner. Any ideas how
to get it out.

Thanks

Almost 100% sure. Outdrive is a pre-alpha (1977)
But tomorrow l"ll give 3/8 a try. Thanks for your
help.

I found a set of left-handed drill bits at Sears or Eastwoods
(well...somewhere). They cut turning the oppisite direction as a
regular drill bit.
Works well for drilling out bolts. Usually snags it part way through
the operation and spins the bolt out.

Drill kit I bought has screw removers for philips screws, would probably
work with allen also. Basically a large reverse drill bit, with just the
point.

Mine's a 77 also, all original, and it's 5/16. Have you actually seen down
in the hole and confirmed that it's stripped? Something that's happened to
me a few times is I miss my target and get the wrench wedged between the
outside of the bolt head and the upper housing in front of it and it feels
like it's stripping.

Called local marina. They say that they saw thru the bolts
from the side!! Little bit of housing gone NO big deal.
Sounds scary to me.
Thanks for all the tips & sugestions you guys have given me.
I'll be thinking about this one for awhile.I'll eventually let you
know how it turns out. Thanks again

I had the same problem on a 76 merc. A metric 8mm(I think) was just slightly
bigger than the 5/16. I tapped it in and it held to get the allen loose.
Good luck.

You could also use a Dremel tool and the cutting disks to cut a slot in the
head of the bolt and then use an impact driver with the flat blade to loosen
the bolt.

The head of the bolt sits recessed inside hole on the OD and cannot be cut
with a Dremel.

Take a dremel with the cutting disk and cut a slot in the middle of the
bolt. So, you cut some of the trim tab at the same time. Be deal, you are
replacing the tab anyway.
