Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

83,
Sorry I didn't get to the glass question sooner, Been busy the last couple days. I have used 18 oz roving to tab in my stringers and transom and than another layer over the tab and running it to the top of the stringers. I'm going to run a lighter cloth like 10 oz to cap the stringers before I close it up. Looks like ondarvr has you squared away though.1708 is the best way to go. I got a pretty good deal on the glass I have but when I get to the exterior of the transom and the top of the deck I'm going with 1708. Great pics of the old slickcraft in the garage!

Hay guys he is using epoxy and the 1708 is [ correct me if i am wrong] 17 oz glass and 8 oz matt , Wouldn't some 10oz eglass work better ?? John

Jcserca,
I might be wrong, ( it would be a first.... today.... this evening), but I checked a few different sources for 1708 and the mat wasn't the standard csm that has the styrene binder in it. It might also depend on who you get it from. I'm gonna check again.

No , what i was trying to say is that matt is not needed with the epoxy !!! I really dont think it will hurt , but it wont add any more strength to it !! wouldnt it be better to use just plan old glass with out the matt ??? JOhn

Hey mark, no problem on the delay. I appreciate all the advice I can get whenever it arrives I'm a little out on ordering that stuff still. Glad John brought up some of these questions cause the were the same I had, lol.

How much structural strength do you think these Gunwale boxes add. The reason I ask is because when I rebuild the interior I'd rather make deck to cap cabinets with custom storage for some of my stuff. they are glassed into the deck and hull pretty well right now.

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

I have that type of boxes in my boat, they are about 4 foot long on either side of the hull and are located about midship, they seem to add pretty good support to the sides of the hull, wether taking them out would be critical to the structure I'm not sure. I would like to find out also.

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

That's interesting,
Mine have those also, but the're just molded in to the entire glass deck. (the plywood deck was laid onto the stringers and then the "deck mold was glassed into place. They don't provide support on mine though. the gunnels are really heavy duty and dont need it. (your gunnels look similar to mine steve.)

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

john,
You're correct, but if you wanted some thickness it would speed the lay up process. Or for example, I tabbed my stringers in with 18 oz and then another layer of 18 over it. If I used 1708 I might have been able to glass them in in one step with one layer. (using epoxy). After all. My original stringers had a single layer of glass about 6" up( roving, with a layer of csm underneath.)

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

yep agreed , but Steve doesn't need to add any bulk to the stringers and the transom !! It would be good if he had to repair the hull or something that shows , and he need to add some thickness, he just need to add the strength , thats way I went with the eglass !!! 10 oz eglass is equal to 14 oz glass !!! John

John,
What about the floor/deck/sole ? If he has to rebuild it from scratch wouldn't 1708 be the way to go? As you said, it's good for the hull or something that would show.

I was thinking not , uuummm, he wants to add the teak to the deck so I would think that Steve would need to keep it thin there also !!! just need the strength, think he said it was a quater inch thick !!! John

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

ok, bell housing and inner transom plates are off!! Guess what, there is no rot around the transom opening. Not sure if this is good or bad.

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

So, I did some more drilling. This next pic is above the floor, port side

And above the floor, starboard side. Wood is in great condition here

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

The lift hook holes above the 1st pic............rotten wood

 

[83mulligan]

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

This pic is of a core taken right under the outdrive mounting hole...... it's wet, but not rotten. a screwdriver does not press in

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

Steve,

Can you tell if the rot in the lift hook is in the reinforcing block or the transom? If it's in the block you have a good chance. But , cut it out and make sure the rot hasn't migrated to the transom. Even though the rest of the transom looks solid, you should cut away the inner skin and check the entire thing. Even if it is all good solid wood, that would be the only way to ensure that it dries completely.Re glassing the inner transom is much easier than replacing the entire thing! BTW I'll have your pics either tonight or tomorrow. I put in a good day stripping the hull today and wanna get the garage cleaned up.
Mike

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

Hey mike. The transom itself around the port lift hook is rotten. Not just the mounting block. On the starboard side, no rot. However, where I've mounted my transducer on the starboard side is definitely wet. Had water come out when I drilled the hole. So..........I'm really at a loss for what to do. I like your idea of cutting the entire inner skin off. I think that makes the best sense. I sure would love to avoid pulling out a bunch of non-rotted wood. I could then focus my efforts on the rest of the hull while that dries and maybe replace some core sections and glass it all back in.

BTW, drilled two holes in the bulkhead of that forward compartment. One near the floor where the water damage shows. Wet wood all the way through. Wet foam behind it in the lower hole. Upper hole....Wet wood, though not rotten. I believe i can cut out this bulkhead, dig out all the foam and replace the bulkhead, re pour the foam.

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

I just need to finish getting the carpet out of the bow area, some accessories and screws off the transom and some cabin and gunwale lighting out and I'll be ready to put on my jason mask and start cutting!

Re: Upon Further Review..#$%@..1973 Slickcraft Trans/String Overhaul

Well, you obviously have had water intrusion, and it's managed to wick itself around a bit. Wet but solid means it just hasn't had the heat to get it working on rotting the wood yet.

I've seen where a guy drilled a bunch of holes in the wet areas and put solid tubes in them halfway down, and then hooked them all up to a shop vac and let it pull a vacuum on the transom for a day. Then he soaked the holes with acetone to displace the water and let it dry out with a heat source on the outside of the hull ( to avoid vapors in the hull from igniting ) and a fan on the inside to keep the fumes limited. Then he used the Penetrating Epoxy to solidify the wood.

Dunno what the long term condition was, but it seemed to have worked pretty well. The time into that is going to be less than replacing the transom wood, but it could ultimately prove to be only slightly more than a temporary fix that would last longer than a full replacement.

When it's all said and done, I could have probably gotten away with doing that with my transom, but being that I live in MN and the boat will be stored in freezing and worse conditions, I can't afford to have any water that would expand within the wood and destroy the bond with the fiberglass, so all suspect wood is simply out.
