Fixing vs replacing engines
I replaced my oil last week, and I missed taking the old o ring off the engine. The net is that I ran the engine without oil, and it seized up. Any suggestions.. is it worth trying to have the enginer rebuilt, or just order a new one? For those who are gonna suggest "New Boat", I am working that angle.. but the Mrs wants a kitchen first.

First you need to see of that engine is rebuildable. It depends on the damage done already.
Next is weigh the cost of a new crate engine.
If your original is rebuildable what's the cost of that.
Lastly compare the power difference in the rebuilt vs new.
In cars it pays to keep the original engine and rebuild due to numbers matching when selling.
In boats it doesn't matter as much.
If I was in your place, if my engine is a 350 and I can get it rebuilt with at least 350hp and 400torque for under the price of a new engine I'd do it.
But after upgrading from the 325 in my 08 to the 345 in my 13 that power and torque difference makes a ton of difference in my driving pleasureMalo <--- Means--Evil or Mean One. This explains a lot.

I know most will freak out about this response, but did you try and free it? Use a lot of penetrating oil in each cylinder and a large breaker bar..
You may get lucky and it breaks free really easily and runs fine(insert ticking time bomb comments) for a time then have it rebuilt over the winter or find a used engine..http://www.instgram.com/jlyons30

O-ring around the filter??
I agree with this comment. My buddy with a 24 Surpa had his motor go out over the summer. That was the 496 bb motor.
For the time, effort, and cost, his decision was to go with a remanf motor.
Once he picked up the motor, he replaced a few other parts (manifolds) and was back in the water.
He was going to go the rebuild route, but any good engine builder cannot tell you EXACT costs until the motor is torn down.
They can get close. This builder knew how to rebuild marine motors with better parts and more HP and Torque. It cost $$$.
There are a few companies that sell the remanf for Indmars. For example, these guys have a bunch of different options. And a Warranty.
Get your old motor number and give them a call for a price comparison. Your in NC, they are in VA - not a far drive.

I did this on the truck once (the filter mounting is pretty buried and not visible). It's a pretty easy mistake... once. I always check for oil pressure as soon as I start the engine and then I watch for any leaks - in this case, I immediately saw oil pouring out and shut it down. I lost a little over a quart in about 15-20 seconds.

I think all the oil leaked out and seized, my assumption.
