78' 256 CC restore back on the table

Recommended Posts

Hey all.. been a couple years since checking in (2016/2017). The boat has been sitting (life got in the way). BUT we will be re-starting on the restore project once again within the next week or so.
Last thing i did to her was cut an access hatch into the rear deck behind the live well and started to remove foam, installed a garboard drain and was trying to figure out what to do with the motors.
So NOW the game plan is to remove the tank and remove as much foam as i possibly can. Install a new tank if i can find something that will fit good (any info would be much appreciated) and i think im going to get a single 225 for now. Transom is still solid- no bouncing, but im sure it wont be long before that needs to be done so maybe next winter we'll try to knock that out.
Glad to be back and cant wait to catch up on the posts!
Cheers!

WELCOME BACK!  Boat still looks good.

225 - I would guess you will be able to run low 40s.  

When you pulled the foam out, was it saturated all the way through or just along the outside  surface?  Curious as to how 35 year old foam held up.  When you created the access, were you able to inspect the stringers?  If so, were they in good shape?  

When you re-do the transom, are you considering a poured composite like CarbonCore?  It seems like more people are going this route than the traditional way of coring with Coosa or similar products.

foam wasnt too bad. It was a little wet around the edges- more so down towards the bottom - there are some pics on here somewhere that i posted a few years ago when i did it. I only removed from the rear of the livewell back to transom. Havent been able to see any stringers as of yet. I need to pop the coffin and yank the tank- thats where im sure i will run into some snafu's.  As for the the transom- i was actually considering seacast or something similar (poured). Ive read mostly good things. If i was going to do a full restore, i would pull the entire deck and do it the normal way- maybe beef it up some.

Got the coffin opened today.. Wasnt as bad as i was expectying but its still looked like crap in there.  Front to tank the foam was dry but seen a little water the deeper i went. Rear of the tank- LOADS of water, rotten foam with a mud-like consistency.  Been copping little by little with a big screwdriver. buzzed the sides with a cordless sawzall and long demo blade. hoses are beyond shot. going to try to get sending unit out tomorrow and set up some sort of A-Frame with a come-along and try to pop the tank out. Im dying to see underneath.

More to come

-cheers

Are there any numbers on that tank or a I.D plate? I was able to go back to the manufacture and get the exact tank made for my 1985 232...they still keep all the old plans...

Replacing tanks is a nasty job.  A pressure washer will remove a lot of it but it does get blown everywhere.

If you go back with an aluminum tank, be sure to coat it with coal tar epoxy to extend the life of the tank.  Also consider seeing if you can have some tabs welded on top of the tank to anchor it.  This would allow not having to foam the entire coffin box.  Would still need to fabricate some sort of cradle to support the bottom.  Another thing to think about is creating a drain from the coffin box to the bilge so water will not accumulate around the tank.

Nasty job indeed! Theres no ID plate or anything left on this tank- at least not on top. Still not done pulling it. Did notice a few holes worn through the top though. Gas fumes are pretty strong but if you give the tank a rapp or two, it sounds empty but i think there may be a few gallons still in there still. Have to find a pump so when i get the sender out (which is going to be a job by itself unless i break it out) i can get a hose or something in there to drain whatever is in there. I have some aluminum fuel line left over from when i built my car so i may use that to get to the rear of the tank. Hopefully i can get this thing out this week.

So when you say weld some tabs on the tank- im assuming you mean that hang over the top edge of the coffin?

Thanks for all the advice!

this is where we left off tonight.  ...

Figured since you are doing this, if you don't mind cutting a slight depression on the coffin side where the lid fits, the tabs could then be used to keep the tank from shifting.  Another option is to find a poly tank that will fit the coffin box as close as possible and install per the manufacturer's recommendations.  They do not use foam around the tank, but instead strap it in place as it has to have some room to allow for tank expansion (I think it is less than 3%).

will the poly tanks hold up to the ethenol? never had one so dont really know. Up here in jersey, theres not many places to get "real gas". Pretty much everywhere has E10. Ive heard rumors that theres a couple gas docks with the real stuff, but have yet to find them.

The poly tanks hold up to ethanol fine.  Moeller states that their tanks:

  • Roto-molded, cross-linked polyethylene plastic is impervious to corrosion and ethanol-enhanced fuel

been a busy week. Still havent popped the tank yet BUT i did score a nice merc 250 over the weekend . Its an 05', only 460hrs, complete with all rigging/cables/prop/livorsi controls/gauges/oil tanks etc.   Did manage to get one of the ol' Johnsons off tonight though. Should have tank out this week if work dont get in the way. lol
