Jasona12380 1969 FB Rebuild
Jasona12380:
Finally made some progress with my 69 FB over the last few weeks. I haven't posted since my introduction in lurking. I want to formerly apologize for the amount of questions/advise that are coming while doing my first rebuild. I've got as far as removing all hardware of the gunnels, freed up console, and aluminum fuel tank. This week a few buddy's will help me remove console and tank. My plan is to close transom in first. I am anxious to see how the stringers/foam look after removing a few feet off nearest the transom. My guess is there will be some water underneath due to age and knowing the anchor compartment on the casting deck was taking in water from the broken drain tube that empty's under the hull. Is there any chance that it may be clean enough under the deck that I wouldn't have to cut out the remaining deck? I ask because the deck is really solid and would hate to add more work and $$ if I don't have to. I plan on closing transom, adding, bracket(swimming platform), and 175 Merc 4 stroke(on order). From what I read, I will likely need to raise the floor after adding the weight from transom and 4 stroke to the rear. This boat has never been left overnight on a dock but will sit on a slip when its back in the water. Hoping for some advise whether to cut the entire deck out after closing in the transom or is it possible to leave as is?

Welcome back.
The inside of the boat looks great. The drain tube in the anchor bay - did it drain outside the hull or into the bilge. The boat was designed to be self-bailing, no access to the bilge and all water kept above the deck - any water ran aft, collected in the trough at the rear and ran out the drain holes. The boat didn't come with a bilge pump. Is your goal to keep the boat self-bailing? I think you'll have to rethink how to evac the water that will accumulate in the aft after you close in the transom and add a bracket. Hopefully you'll add a bracket that includes flotation. That will help offset the weight of the engine and the distance it is offset from the transom. You'll have to raise the bracket on the transom an inch or two to help raise the engine because of its offset off the transom - usually each foot offset requires raising the engine an inch.
Are you going to keep the fuel tank above the floor inside the console? Usually, weight is moved forward to offset the added weight of a 4S motor. Looks like the batteries are up front already, so there isn't much more to move forward. If you try to move the console/tank forward, you'll have to also move the ledger that the console sits on - more holes in the floor. Looks like you can only move it forward about 10" anyway, which will help.
Also, use the gallery we provide for you, to upload your pics. Follow the instructions here http://classicaquasport.com/smf/index.php?topic=12725.0 - don't attach them - you are limited by file size. Uploading them into your "member gallery" is better for viewing.
Spend a few minutes to absorb the instructions. It's really easy. Remember if using a phone to take pics, to hold the phone horizontal with the lens to the left.

Thanks RickK. The drain tube from the anchor bay to outer hull was cracked during the last season this boat was used. Looks like some water flowed in from the hull when there was weight on the casting deck. It was damp in the right side compartment under the casting deck. Looks like its plywood inside that compartment. I'm anxious to see what it looks like under the deck this week when I start cutting the rear floor in prep of closing in the transom.

Welcome to the forum and congrats on a great project boat to start with! She looks to be unmolested and in good shape for her age. I have a 1970' that I will eventually get into when I finish a few other projects. Like yours mine has a solid main deck with the exception of around the forward bait well in the main deck. I think exploration could be done after cutting back 18 or so inches in from the transom to see if the foam inside the stringers is wet. However, considering your planning on putting 175hp on there, and will likely see decent seas up there, you might want to do as much exploration as you can to the stringer tabbing because its common for these hulls to have tabbing that is snapped off from age and use. Wet foam, pounding on the hull bottom is disaster for stringer tabbing failure which will ultimately results in hull bottom cracks. I am not trying to scare you but I have seen a number of these hulls that have crack hull bottoms with stringers that look to be original. However, a lot of this is adding much more to the hull in the way of weight by leaning post live wells, transom live wells, towers, larger fuel tanks, etc.
Looking forwards to seeing the progress and thanks for learning how to post pics as it make it much easier to see things and understand so we can help. :)

Thanks Ulysses. I met with a Sea Craft restorer today. He a good friend with one of my good friends here on Cape Cod where my boat and my business is located. I saw him on the water with his 24 Sea Craft a few months back after having let go of a 1000lb tuna because commercial was closed. I won't forget that day, lol and definitely loved his Sea Craft. He came by today to check out the project and is willing to help me along the way. He looked at the floor and feels it's a little soft on one side of the console/baitwell. He also noticed stress cracks on the gunnels and assuming the stringers are delaminated in some areas like you mentioned. We agreed there is no better time to address this than now. Next Monday he's going to come by and mark exactly where to cut into my floor to see how it looks. I will post some pics after getting underneath.
