Can anyone identify this tool?
When I recently bought my boat I found this piece of kit amongst a miscellany.
It measures 180 x 170 x 45mm and has a square key on one side and a splined key on the other.
All steel construction. It weighs 5 kgs.
Could it be something to align/fit drive or propshaft to gearbox, or gearbox to engine?
I am loath to throw it away but also really don't like having redundant/useless kit aboard.
Any ideas?
Thanks in advance.

Re: Can anyone identify this tool?
looks like some kind of home built drive/adapter...is that a 1/2" drive socket embedded in there? what happens when you spin it?
maybe a make shift windlass drive/adapter for a electric torque wrench

Re: Can anyone identify this tool?
I love puzzles!
I want to guess it could be a bender of some sort? Both of those bolts back out and it appears that they have some kind of jaw to them to clamp with.
Do you have anything on board that that socket would fit on? It looks like a fairly large socket with a 1/2" drive.
Maybe the clamps held something to hold that box steady and then you spin something else with the socket? Engine perhaps? Maybe a backup starter?

Re: Can anyone identify this tool?
OK, I am thinking it's a torque multiplier of some sort. Perhaps with a 3:1 or 4:1 gear reduction. Put the winch handle in one side and get a slower, more powerful drive for a socket on the other side. However, this would require a large arm to hold the frame of the device to keep it from turning. In other words, you need to restrain the outside from turning.

Re: Can anyone identify this tool?
I cannot see from the picture what the bolts do. Are both bolts similar?
What happens when you turn the bolt? Does a jammer-piece of metal extend from the side of the box?
This is certainly a jig to hold the socket while force is being applied through the half-inch square drive. Maybe Lots of Force. What needs this?
Fun.

Re: Can anyone identify this tool?
It looks like a largish socket. Maybe designed for a specific task such as accessing a bolt/nut which is recessed in a difficult area? The square shape fitting into recess or stabilizing the socket.

Re: Can anyone identify this tool?
That’s a 1/2” drive and a twelve point socket on the other side. Take it to a hardware store and find a bolt that fits the socket, whether metric or SAE (American). Then you’ll have part of the answer. Look and see what size bolt or nut you have on the boat. Most likely something like the nut on the crankshaft.

I asked an old farm boy/motor head/truck driver...he doesn't know either.
Sorry.

Re: Can anyone identify this tool?
if you look at the photo you will see a pin going thru the socket in alignment with the two square pins.

The only time I have used one, I used it to tighten the nuts on 1" and 1 1/8" keelbolts.
I should point out that this wasn't entirely successful in that the keel eventually fell off...

Re: Can anyone identify this tool?
tough on picture but will winch handle fit into socket? Then rotation creates either ratchet or spreads the clamps?
Then begin looking for a dark place that has a fitting that obviously was installed during boat assembly......(prior to deck install or similar)
like tension ratchet to assist installing alternator belts and getting tight?
