1986 22-2 Osprey DIY

[Nfratino]

Hello all. I have a 1986 22-2 Osprey that I plan to spend the next two months doing some work on. I had a few questions i was hoping to get some feedback on. I plan to redo the floor due the the various soft spots around the console/coffin box. I also plan to repaint and roll and tip the topsides of the hull. The main question I have is on the transom. There are no major stress cracks but the top cap of the transom has a crack in it. I was planning to pull the swim ladder off/potentially do a test hole to see what the core looked like. I would really like to not have to re core the transom if not needed. Any input is appreciated.

Thank you

If you are talking about a crack that is about an inch from the top of the transom, that is normal (the liner comes up and over the transom and is the joining area of the two) but can be a source of water intrusion and would need to be sealed up.  Make sure the transom is sound by tilting up the motor, lay across the lower unit and bounce a little on it, watching the transom for flex as you do.

RICK,

Thanks for the reply. It seems like a thin flap that has pulled away so im assuming that is the liner. It was caulked when i bought the boat. I have moved the motor a ton and have not noticed any flexing. I removed the swim platform tonight and the screws came out dry. The boat hasnt been kn the water for weeks but im assuming thats a good sign.

This is what the crack on my transom looked like


Here is what the inside looks like under the top of the transom.

I will try to get some pictures up tonight. My crack is on the inside of the transom all the way at the top seam of the transom running horizontally. Is the move here to cut out the cracked portion and refill with coosa? I would rather not continue to caulk the seam.

You can use a dremel to gouge a little out along the crack and then fill it with thickened resin and paint over it.

Well i am in full deck replacement mode now. Once i figure out how to post pictures from my phone we should have some images. Once i sorted/labeled all my wireing i was able to get the coffin box cover off. The cover was completely saturated and weighed at least 200lbs. I was please to find no fuel smell beneath just a very grimy looking tank. Not sure what my next move is with the tavk but my main priority is to get the new deck in. Does anyone have pictures of how to new deck will interact with the coffin box/tub? My plan was to cut around the perimiter of the deck, leave a 6" lip to tie into and replace with coosa. is it typical to go on top of the coffinbox and pad up? any pics of these flooring details specifilly would be a big help. i hate to start cutting away the coffin box thats in good shape.

Most people who do a full deck replacement scrap the tank coffin and make their tank compartment with bulkheads.  You'l find plenty of examples in the rebuilds of this.  Another option would be to keep a lip when you remove the coffin and reseed It into your new deck.  If your coffin was like mine, part of the deck/liner assembly, I'd want to do more than just lay my deck over it.

Here are some updates as to how to boat sits. I would like to retain the same tank and box if possible. I will most likely make a new hatch that is removable. I am up in the air about the tank. Any tips on getting the fuel and lifting the tank out? It probably has 10-30 gallons in it since i used the boat during hunting season. I could go to a smaller poly tank but if the factory just needs a good cleaning id like to stick with it. My plan for the the deck is to leave a 4-6" lip around the perimeter to but the coosa too and then glass and tab up the sides up of the hull. Not trying to make a show piece here but want it to look decent at the same time. This boat is fished/crabbed hard in the Chesapeake bay. Any input is helpful. Thanks.

Any tips on getting the fuel and lifting the tank out?

I used a bulb type siphon kit to drain the old fuel through the sender hole.  A couple of 5 galon glass cans and three trips to the hazardous waste facility at the land full and the fuel was gone.  Once empty, the tank is manageable.  I think I removed my 70+ gallon tank by myself.

[RickK]

Nfratino, you can remove the coring from the back of the tank lid and recore it easy enough - plenty of examples of how to do that here.  For the lip around the tank you can cut that out and re-use it also, build up underneath the lip to compensate for the thickness of the material you left around the perimeter (if you're going to lay new flooring on top) and glass the lip to the new floor material.

[Nfratino]

Thanks for the input guys. This is my first stab at a deck repair so we will see how it goes. I think i am picking up what your saying about the lip. My plan was to leave a perimeter around the coffin box and butt into that rather go on top so everything stays in the same plane. I will essentialy have tabs around the perimeter of the deck on the outside and around the coffin box for the new deck to sit on. Or is it possible that i could split the difference on the stringers where the lip rolls down into the coffin box.

[Nfratino]

Made some progress today. I was surprised to find the majority of the flotation foam that was in place was dry. I pulled up any foam that was loose from the hull. The stringers seem rock solid but there are a few spots where the foam seems damp. I really dont want to get into a full overhaul since i am not removing the transom. I plan to use the same coffin box, it looks like i can remove the core from the lip and slid the new deck into it then glass on top. I plan to re core the coffin box lid. The starboard side flotation foam seems very solid, has anyone poured directly on top of this? I am not sure why there were cutouts left in the stingers. Wouldn't the factory have glassed over this once the stingers were filled? For the outside perimeter lip i plan to screw a 2x6 or some sort of material that i can get a good bite on when i lay the floor. This blocking will be glassed to the hull and foamed in place. Does this method sound feasible?

I am having a hard time making up my mind on the fuel tank. I plan to drain it tonight, remove and clean to inspect. Im assuming this is the original tank. When i removed the coffin box lid there was not any standing water and it was pretty dry, the tank is just discolored greenish. I really dont have in my budget to replace the tank due to cost of glass and coosa etc. Has anyone rolled the dice on a older tank? Keep in mind there is no fuel smell in the coffin.

You can always have the tank pressure tested. If the tank is original that would make it 30+ years old, if it were me I'd replace it. Last thing you'll want to do after you get her floating again is pull and replace the tank.
