Re: 1988 Sylvan Offshore 22'

Couple things real quick...

I've used that Blue Sea Fuse Bock and it's very nice to work with.

For Poly you really need to also fiberglass (it'll crack pretty quick otherwise). If you are using epoxy you wouldn't necessarily need to glass.

But if you have it on hand, why not eh!

Cheers

Re: 1988 Sylvan Offshore 22'

Well I gave it heck this evening, instead of feeling better...I feel kinda worse!

I First started on removing the helm and birds nest of wire from the cuddy wall , after 1 stubborn screw (stripped) I finally got it removed , It now hangs by the mass of wires.... Im going to spend some time tommorow after work salvaging what I can , gauges , switches etc.... most of this wire and strreing & cables will be trashed... I am going to do my best to salvage though!

Finally got the helm off the cuddy wall and tried my best to remove it, the floor was so rotted it swelled and made this SO HARD... I had to use a prybar and move the top an inch then the bottom , then the top , then the bottom...and so on.... finally I got it out and in good enough shape for a template.

Re: 1988 Sylvan Offshore 22'

After I got the wall out , I had to do something that pi$$ed me off! I had to literally destroy the cuddy bed frame to get it out, vinyl and all... I had to drill the rivets (Im starting to hate rivets and Im not feeling good about the ease of replacing them) ant I tried to remove the whole frame in one piece with the help of my family... after I got it out into the lawn and stared at it... reality hit me... it needs all taken apart (more freakin rivets) and new sections cut on new wood , re covered in vinyl and I dont know how Im even going to be able to re-rivet it back as sturdy as it was before I removed it... I never played with rivets see!

Im assuming I have to drill new holes in the wood and metal thshoot a rivet , instead of lining up on the old holes... which would be impossible??





Moving forward I removed the carpet from the bow area , which left a huge mess of glue and crap all over the inside of the hull , then I got another unwelcome suprise....

Re: 1988 Sylvan Offshore 22'

I began taking out the very front piece of the bow , careful because I also plan on tracing it on new wood... where I found out the wood.... is only 1/4 inch plywood... I was planning on using 3/4 for a solid deck , complete with glass & mat.... which will throw off my cuddy cabin height ... I thought maybe just the front section was 1/4" but I removed a second piece and its also 1/4" so Im assuming the whole boat it... so I can deal with that now....




Then another unwelcome suprise...

Re: 1988 Sylvan Offshore 22'

foam , lots of it.. at first I was ready to cry , not wanting to scrape and remove it (been there done that before) but after I calmed down I started feeling it up... I know someone reading wont like this but...... I DONT hate this foam so far , in the bow at least....its HARD and appears to be in good shape , Im hoping the rest of the foam in the bigger part of the hull (which I will see soon enough) the foam is in the same shape... if this foam looks and feels solid and good... Im not sure I will remove it.... I was just going to pour it full of new foam anyhow... If I left it in there , the deak will lay perfectly flat where it should be , if I keep the foam , my job of laying new deck will be FAR FAR easier... I know I have to remove the main large sections of the deck before I make my decision , but Im praying the foam looks like it does up front...


Also , my wifes side of the garage is now full of a SERIOUS PILE of vinyl and parts , tanks and wood , all needing repair! This project will drag on into the winter no doubt.... I have to get it in my head Im in no hurry... and I have to get my wife motivated into re-upholstery

Seems she has as much work as me but she doesnt know it yet! ...


After I get the helm and decking out , Im going to pour my energy into getting all my replacement wood , deck , panels , rails cut and laminated , and out of the way before cold weather makes glassing nasty

Opinions??? Im ALL EARS

Re: 1988 Sylvan Offshore 22'

That plywood should be 1/2 inch on the floor. The only 3/4 is the cabin wall. Are you sure it's not rotted and delaminated enough to appear to be 1/4? Be great if the foam turns out to be dry and solid. My 82 had the white bead type styrafoam. What wasn't wet had turned to loose beads.

Re: 1988 Sylvan Offshore 22'

I will double check the thickness this afternoon after work!

Can Anyone tell me the shelf life on this foam?

Re: 1988 Sylvan Offshore 22'

Don't be too mad about all that wood in the cabin. I was planning on keeping mine at one point, got into it some and was really glad I did. Might as well make it all new since I was making it all new anyway. I think you'll be happy you replaced it in the end.

Rivets are really easy, don't sweat it at all. You'd really not want to try and line all that stuff up anyway. New 3/16" holes, sealed up with 5200 (or 3200, 4200) and pop em in, easy.

You can use thicker deck and just adjust your cabin walls, no biggie there.

That bow foam ought to be dry as water doesn't really sit up there. As you work your way aft I'd be surprised if you had dry foam top to bottom.

Can Anyone tell me the shelf life on this foam?

I'd venture to say forever so long as it's not sitting in water.

Great tear down progress, keep on it!

Re: 1988 Sylvan Offshore 22'

Jason is correct to a certain degree. The problem is with the cabin interior. It has to work out to the height of the angle that is riveted to the hull on the sides. Way to hard to modify the u shaped piece to change the height.

Re: 1988 Sylvan Offshore 22'

A little frustrated last nite. . I hate breaking rivets that i know i have to put back! I just had the idea of finding some interior screws to mount the cuddy frame to the flange instead of rivets , whatever i find must look nice on white vinyl

Re: 1988 Sylvan Offshore 22'

So i better match the decks thickness instead of trying 3\4 inch. . I guess i can use glass mat to strengthen it where it will need it

Re: 1988 Sylvan Offshore 22'

I guess i will have to give rivets a try before i worry lol. Dont worry im going to keep on it. . Today im going to sort out the helm. Wires cables switches and gauges. . And drink iced tea and sit in the sun on my half of a rotten deck. Ahhh the good life

Re: 1988 Sylvan Offshore 22'

Also Im going research the tools I will need for new vinyl , my wife has a talent for projects like that, I hope she picks up upolstrey!

Re: 1988 Sylvan Offshore 22'

The rivets are very easy but can be a pain with a hand tool. Do your self a favor and get a pneumatic gun from Harbor Freight. Really saves on your hands as the 3/16 rivets take a good grip to set with the hand tool.I was amazed at how well the pneumatic gun works. Most of your upholstery is very simple on that boat. Hardest part is sewing the cushions. If your wife knows how to sew and has a machine that is heavy enough should be no problem.

Re: 1988 Sylvan Offshore 22'

Steve , thanks for the advice on harbor freight.... I will do just that!!

Also thanks for suggesting that the floor be rechecked . I found a thick piece and measured it , it IS in fact 1/2 "

You wouldnt believe how thin it is in some places ......



So much for making a template , I went to remove section 3 , and the wood turned to mush , no way I was getting it up...


As for the foam , its all garbage to , seems the factory pre formed blocks of foam in the center of the boat , they came out whole but they are brittle , except at the bottom where they are HEAVY with water , as with my old MFG job , this foam is SOAKED and HEAVY , I cant imaging how much weight Im removing by doing this!

Im all in now !

No turning back!

Re: 1988 Sylvan Offshore 22'

like to add that the foam was poured on the sides and wont be so easy to remove

Re: 1988 Sylvan Offshore 22'

Let me ask you this... Say I buy this panel , and I bolt it to say the new cuddy wall under the helm. I bolt it through the 4 mounting holes.... then I connect the batterys negative terminal to one of the 2 posts on top of the panel , then connect positive to the other post... Then to power an accessory I would plug it onto one of the connectors next to a fuse right? Where would the accessories ground wire go?

View attachment 162477

Ground goes to a Negative Terminal Block. The negative battery (black) wire goes to the NTB. Red wire goes to your fuse panel. I mounted both block close to each other.

Re: 1988 Sylvan Offshore 22'

Well I got more accomplished this afternoon , and I may be out of business until Friday , because I have no more garbage capacity! I have all my cans full of deck , foam , wires and the big cans full of carpet.


The deck in spots was razor thin and stuck to the foam.

No exaggeration to say that the only thing keeping your foot from snapping through the deck every step , was the fact that the big foam blocks were so tightly packed in there.





I got all the wires , cables , harnesses etc removed , as Im starting fresh with the electric.


This foam that was poured on the sides , I forgot how fun it is to deal with ..:-(

Re: 1988 Sylvan Offshore 22'

I also found right in the very front of the bow a piece of wood rotted and broke , should be an easy job to replace it , but after finding it , I came to the decision that even the wood that looks good around the sunroof , is also coming out , I feel that I stripped 95% of all the wood out , and 90% of that was rotten to the core , Im not leaving ANY wood in here , its all coming out. Should be easy templates as they will come out in 1 piece , easy removal to (nuts and bolts)
