Thumbs down Need to adjust timing, but dist is seized to engine block.

Now the my boat is out of the water for winterizing, I thought it would be a good time to convert to electronic ignition. Everything went well enough, but the timing was off after the conversion so I went to spin the distributor (hold down clamp is off) and it is frozen solid.

The distributor body is aluminum and the block is cast iron so I'm sure it's galled together pretty good.

I have tried soaking in PB blaster, ATF+Acetone mix and MMO. I soaked the distributor with "freeze spray" to try to get the aluminum to shrink and break the bond with the block. I've also tried moving with a punch and hammer but I'm being very cautious as I don't want to end up with 1/2 of the distributor in one hand and 1/2 stuck in the blck.

So far nothing is moving.

Any other tricks people know about? Has anyone else experienced this?

Spray starting fluid down the dipstick tube and drop a match to pop the distributor up like seating the bead on a tire???

Seriously, have you tried any gentle lifting motions with a prybar? Good luck with this.

I have not tried lifting the distributor yet; should that be my next move? So far I have only attempted lateral movements.

That is what I would try next, using the same cautious approach that you have been taking. You will need to make sure you don't damage the underside of the distributor housing. Perhaps get a metal plate under it to spread out the force.

How long was the distributor in the block before you tried to move it?

That's a great question; I bought the boat last year (it's an '87). No way to know for sure.

You might try gently tapping down on it also trying to get some movement. The rubber o-ring might have turned to stone.
