    Default 1981 "SpaceCraft Boat Works, Miami FL" 23.33ft 4100lb V240 Super Sport

    I just procured this boat, it had been sitting for some time and was bought from probably the original owners. I traded a 1996 1100zxi 2-seater kawasaki jetski for it.

    Engine Running!: (PRIOR TO DISCOVERY OF CRACKED CYLINDER)



    Engine re-assembly after machine shop visit for a new block:


    Engine installation into boat:


    Outdrive Installed:


    FIRST RUN!!!



    I'm excited about this project for a few reasons.
    1. This is my first boat
    2. Spacecraft Boat Works is a very well known company in florida, but hardly known of elsewhere since their closure in 1991 (or 1993?) (along with a great many other boat companies at the time). I am very excited to be bringing one of these back to life.
    They used to make the fiberglass nosecones used in the Space shuttle until they lost the contract and as a result began making boats.

    3. Boats made of all fiberglass are EASY to clean / restore and bring new life back too due to no wood rot issues to deal with. I am finding this to not necessarily be true though due to the transom having wood.
    EDIT: The entire transom had to be replaced, so that wasn't true at all.
    EDIT: You know what forget I said anything about this being easy.

    Any comments, suggestions or input would be appreciated.

    There is a new 305 chevy 5.0l OMC included in the deal which i'll be installing. As you can see, it's "new to you" but certainly not a new motor. It will probably need some work as well.

    Updated with new pics. Got a shop vac and went to town. Cleaned out the entire engine bay too, now just need to remove the old 305. Going to try and do that this weekend.

    Wow www.sterndrive.info is such a great resource for this OMC stuff!!!
    I haven't been able to find one part though, the big accordion looking bellows that goes around the entire outdrive at the transom. This evidently is what allows everything to move as one. I want to replace mine before moving forward since its an obvious dry-rot prone part.

    Sorry, no offense intended, just that buffing and cleaning fiberglass can be very time consuming and hard work..

    Hey no prob man! And yeah it can be quite a bit of work, but not nearly as much work as stringer replacement and re-glassing. Now THAT makes me wanna throw the towel in!!!
    I don't mind a little scrubbing, pressure washing and wet sanding / buffing. You don't pass out from fumes, or have time limits haha.

    From what I can tell not a single piece other then the teak doors, occasional teak trim (to place fishing rods on on the sides) and teak swim platform and kicker for an emergency outboard.
    I am going to remove the aftermarket seats that were installed next and open up the main bilge panel in the floor. I believe that is where the fuel tank is, i'll know more once I get in there I guess.

    From what I understand on boats like this, they used a steel beam or something else for the main keel stringer, and fiberglassed around it.

    Let me ask you guys something, if you open the filler cap for the fuel tank (which hasn't been opened in probably 6yrs) and a MASSIVE vaccum nearly keeps you from pulling it off, and when you do it sucks cavernous air in, is that a good sign?

    I take it as a sign the fuel tank is still sealed / intact with no leaks! Also it had 0 smell (not even a fuel smell) which means it was probably drained. I'll know more when I get the panel up this weekend but just thought i'd ask.

    Well the weekend is here, I plan on working on the boat the whole time. Going to remove the old seats, get the floor panel up and check out that fuel tank.
    I am also picking up the new engine and bringing it back to look at. I just realized that i'm missing a lot of random cooling hoses, fuel line and what looks like every single bolt for the bellhousing.
    Hopefully those things won't be very hard to procure and at low cost.

    It shouldn't have a vacuum if it was properly vented. I'd definitely be checking for a blockage on the vent.

    Yeah good point, i guess i'd rather have a stuck vent then a busted tank though (if the choice were mine to make) so i'm still on the winning side

    Just picked up a Ford 302 that is freshly rebuilt. Not sure whether or not i'm going to put the 302 or the 305 chevy in there. It would appear I have the bellhousing type deal for both so I can mate either one up to the stringer.

    The OMC chevy in my pictures was pulled from a boat, no idea what shape it's in. This ford is brand new, so i'll probably go with it.

    Yeah sorry first post has the link.

    I am leaning ford right now, simply because it has an alternator, fuel pump and complete wiring harness (i pray it fits what's on the boat from the OMC panel)
    The only thing it lacks are manifolds, not sure how pricey those are, I have the risers already.

    Correction it also needs a water pump. The one on it is brand new, but is automotive and therefor sticks out WAY too far (pulley)

    I wonder which one has more missing parts then the other LOL

    That cleaned up extremely well. Amazing. Just gotta figure out how to clean up those rust stains and it'll look like new.

    Thanks dude!
    I was so proud of the results, my girl did a ton though I have to take my hat off to her on this one.

    I think we are going to try some acetone for the stains, that should help with that. But yeah all the marine growth and debris stains came of with the bleach / degreaser combo perfectly. Couldn't be happier.


    I think i've decided to go with the Ford motor since it is freshly rebuilt and the number of components required to get it operational are fewer than the Chevy.
    I bid on some nice exhaust manifolds / risers on Ebay, and i'm also going to get a new transom seal boot and alternator pulley since I don't have one.

    Maybe throw a post up in the general boating section. I know there've been threads before about removing rust stains I and know there have been some good ideas tossed about.

    Those are great "Before and After" pics. It's amazing what a little elbow grease can accomplish, isn't it? I always think it's sad to see a cool old boat like this get neglected, but to each his own, I suppose.

    Actually, Wally World has some degreaser in their Marine Department in a dark blue bottle that works really well. I just traded for a jet boat that was living under an oak tree and it took off a lot of the "stains". You might try that before the acetone. Keep up the good work and if I had a vote on the motor, I'd say 302 Ford. Mainly because you stated it had just been rebuilt, but also because I think the 302 is a stronger engine. Keep us updated and keep those pics rolling!

    Try Sno Bol Toilet Cleaner and a Scotch Brite pad on those Rust Stains. It works GREAT!!!!! Wear a mask and gloves cuz it has an acid base to it.
