I guess now that I've been edukated..I'm asking how to attach the coffin to the new deck... that had been not so delicately removed from PO...are drain plugs a good thing for the coffin?

If you left a lip around the coffin box when you cut it out, say an inch or so, you could route out the area of the deck where the lip will sit and just glass it back to the new deck. If you didn't leave a lip, it will be somewhat more difficult. You will have to find a way to get it attached to the new deck. You could attach it to the deck before the deck is installed, or put braces under it to hold it in position so it can be glassed to the new deck. As far as drain holes in the coffin box, mine had 1 in the stern part of the box, not sure if it was there from new, my new box under the floor has drains in it.

Thanks gman, most of it has a lip around it...so I will be able to set it as well as support from the bottom...I guess my main concern is cracking where box meets the deck...

If you can get a couple of supports under the coffin, and you get good adhesion to the new deck, thinking 2 or 3 layers of tabbing glass and resin, you should be good to go with not to much worry about cracking. I would recommend starting with 4 inch tabbing and then go for the first layer of cloth on the entire floor( bring the floor cloth to the inside edge of the coffin) then come back with 8 inch tabbing before your last deck layer, leaves you with 4 layers around the coffin lip, should be pretty strong.

gottcha...thanks, now to find a gas tank.

Check out" greatlakesskipper" website they have a bunch of different size tanks, poly and alum. I put a 55 gallon tank in mine in place of the 45 gallon original. Went with poly as well. Prices aren't to bad..

The coffin was originally mounted with aluminum angles screwed into the deck, and yes, a drain is a good thing.  The coffin has one angle on each side with 4 screws and another angle at the front with 4 screws.  There is a drain in the bottom rear of the coffin that was originally plumbed overboard through a drain in the deck that matched up.  There is a cutout in the stringer on the starboard side that allows the drain line to reach the outer hull, and a through-hull fitting for overboard drainage. 

So you could get some 2x2 aluminum or stainless angle and drill holes to match the ones on the coffin, then screw it down to the deck with some good 5200 bedding and sealing.  That's the way they did it originally and it seems to have worked well for most folks.

OK,
I was going to post pics showing GF's description above but.....

I'm guessing you are asking about mounting the tank compartment (aka tank coffin) as opposed to what we call the "coffin box" on a CCP since you have an Osprey. I have pics for a CCP. There was no factory installed, above deck "coffin" on the 196 model Osprey.

Gman's mounting suggestions seem to be the info you seek.

Good luck and post up a few pics of your progress.
