Crap - it's locked up - now what?

UPDATE: Well, the carb has not been off so it can't be foreign matter in the motor.
I put the counter rotating starter on the motor and hit the key - it wont spin in the other direction either. Plugs in or out. NOW WHAT?
I looked at removing the transmission but these are borg warner 71Cs and the rear of the motor is supported by the transmission stringer mounts. How do I remove the trans and not have the motor drop?
I might pull the carb and intake and soak the pistons more....what else can you suggest?
Please guys - pictures of what you would do to pull the trans would be helpful.
Many Thanks

i'm having a problem thinking it's an internal engine problem....
it ran fine on the flush process?? and you had good oil pressure?? nothin unusual.... no water in cylinders or oil.... no wierd noises...
seems to me something came loose in the bellhousing area, and the flywheel is locked against the block, maybe from a loose bolt, or something of that nature...
unless the crank is welded to a rod journal.....

My guess is that it is not the motor if it won't spin at all in either either direction.
A broken rod/other clearance problem should allow you to turn the motor in the opposite direction to temporarily "unjam" the clearance problem

I agree guys - so how do I back a transmission off when it holds two of the four stringer mounts? It;s BW 17 velvet drive and has two mounts on it's sides to hold up the rear of the motor....

I believe the coupler for the transmission has a spring damper in it. Pull the starter and put a breaker bar on the crank bolt. You should be able to see a slight movement in the fly wheel due to movement of the spring pack, if there is no movement then you probably have something stuck interanal to the engine like the rings being rusted. Had a similar situation in the past where the rings were stuck.

We dont have this figured out yet??
Where do the mounts bolt to the side of the trans or
inbetween the trans and the bell housing?

If it is between the trans and bell then you can make three
long studs and remove three bolts then screw in the studs
remove the other three studs and slide the trans back off
the studs. The studs will support the weight.
If it bolts to the side of the trans then you must attach
a chain to a couple of bell housing bolts and use a
support with a come along to take the weight of the rear
of the engine.
If you are not comfortable or understand the above suggestions then I would take it to someone who can swing a wrench.
Good luck

nope - I got it Knot right - but the boat is in the water and has side mounts. I will put a support plate to spread the laod and use a car jack to support motor while I pull back the trans...next weekend.

Loosen All belts,checking for a siezed alternator,sea pump,power steering pump.
If you have access to a bore scope look at the cylinder bores, then with the starter off look at flywheel bolts and for any debris wedged between the starter ring and bellhousing.
Then, you can remove the valve covers and look at the rockers and with the bore scope, look at the lifters to make sure the push rods are in there respective sockets.
Then you can remove the distributor and look at the distributor gear and bore scope the cam gear.(if you turn the motor with the distributor out you have to find top dead center before putting the distributor back in)
