From just repairing a floor to transom to stringers........FULL RESTORE

[purito23]

After a month looking through the website for info on repairing my floor. Finally decide to jump into it . From just a simple floor repair its become a full restore. Rotten wood everywhere. From the bottom up floor, transom, stringers, etc. Im new to boating and thank god for this website(oops) and you tube(friscojarretts).Its given me the nads to try to tackle this head on. The boat is a 17'bow rider w/ a 90HP Mariner outboard. Not sure the manf. of the boat but its sea .. something and no its not a searay.Ill find out tomm.Never did this kind of work before so im gonna need help.Here is where im at almost a month into it.Removed the transom and all the wood.All water logged foam. Basically i gutted the boat out .If i uploaded the pics right can anybody tell me if i did something wrong so far n whats next.Thanks for all the help.

Looks like you've made a great start. Take lots of pictures and measurements (I even made a drawing) to help out on locations of everything. Then you're ready for the best part......

THE GRINDING!!!! :facepalm:

That's the thing about those glass boats, they rot from the inside out... and by the time it has gotten to the deck everything else is rotten.

Keep you boat covered and dry when not in use after the resto and it'll last you a long time.

Re: From just repairing a floor to transom to stringers........FULL RESTORE

hi buddy.....

really great job on the gut.......you area almost done.

take measurements from the keel line out...(the center of the boat......the lowest part. that is the low part ((center) ) of the transom, to the tip of the bow.

that is the keel line. all measure ments are now taken from the center line out...(boats are not symmetrical) so every thing is measured from that reference point.

the other thing is that the rule of thumb is to replace what was there.....
so.....take a string line....and approximate deck height by using the old marks.
run the sting line to each side of the top of the old deck.....from gunwhale to gunwhale...

take this measurement at every four feet from the transom.

then ....measure from the stringer location to the string...subtract 3/4 of an inch...(the thickness of the 1/2 inch deck, and layers of fiberglass of the total deck)...that will give you your new stringer height.

then grind out all the old glass channels....

now make the transom.....use the ideas in my thread below....or in friscos vids.....and install the transom.

then pm me again....and we can move on to stringer installation.

but your work really looks good....

one thing....very important....
what kind of support do you have under the boat? it is crucial that it is not a roller trailer.....this will cause pressure points on the hull during stringer installation.....you need longitudinal supports on the hull.....just like trailer bunks.....so if you dont have any real support of the hull.....make some now before you do the stringer installation.

Got any overall pics of the hull? I'd like to see what we're working with here.

@ fool
i made a couple of drawings and measured like 3x already. Gonna mame sure n measure once more.better safe than sorry.

@jig
trust me after all this work im about to do.she will be coverd from head to toe.even from those summer showers.i have a quick question to all who read. Ive noticed most people dont cover their boats after they take it out of storage and use it during the season. Shouldn't it always be covered even during the summer?

@oops
today i put in like a couple of hrs building my cradle today. Gotta make a few adjustments tomm to be finally done. So tell me what u think so far .ive noticed how more solid it is now. I guess i did a classic rookie mistake walking in the hull while its on the trailer gutted up. I will be learning alot more with u guys. Keep the great info coming.

@ez
everytime i remeber to take a pic of the entire hull my battery is dead on my phone. Will get one tomm.


It seems hard to find info on the manuf. Of this boat. Can anybody tell me why? Its a 1985 17' sea raider.thats what all the info i got from the title and the inside of the hull.

Like you, I have a lot of time, effort, and money in my boat and it is covered when not in use.

The people that don't cover or garage keep their boats when not in use don't realize or don't care what they're doing to their boats. I'm sure most people don't realize what the rain and sun does to their boats when left uncovered, but after doing a restore they will!

How did you get the wood out and leave the glass channels? Was is that rotted that is just came out real easy?

 

[purito23]

Re: From just repairing a floor to transom to stringers........FULL RESTORE

Not sure if it was the right way but i took a chisel and a hammer. Carefully seperating the wood from the channel and prying it up as i go. Thats when i noticed my stringer was in 2 pieces connected by what seemed like a 1x6. Im not sure if the boat came like that or most likely someone worked on it already.It worked for me now i got good templates for the new ones.If i were u ill asked the pros on this forum before u do what i did. Im a rookie just like u.

Re: From just repairing a floor to transom to stringers........FULL RESTORE

It's not a good idea to try and "Re-Use" the channels for your new Stringers. Best recommended method is to cut em out, grind em flush and reset and reglass the stringers. It will be much stronger and in the long run easier than trying to use the old ones and make em adhere to the new stringers. Many have tried and discovered it is not the way to go.

Re: From just repairing a floor to transom to stringers........FULL RESTORE

@wood
I wasnt planning on using the channels i just wanted to get the stringer out as a template. I wanted a general idea for my measurements. But thanks for the info. As far grinding i started today the transom area.What is the right way of doing this? How much down do i go? Do i install the transom first then continue grinding where the stringers go and then rest of the hull or do i keep grinding away makeing snow (lol) before i install anything?I was useing a 4" flap disc.Thanks Kevin

Re: From just repairing a floor to transom to stringers........FULL RESTORE

Kevin, I recommend you do ALL the demo and grinding first. Get the Hull totally clean. I also recommend using a rubber backup pad and resin coated discs. They really work much better and faster than the flap discs. HF sells the BU pad for 5 bucks and the the discs for 75Cents each. 24 grit works great. When you're ready to go back, yes the transom goes first then the stringers so you can tie them into the transom. Have you looked at the drawings in the first link in my signature? Good info there.

Re: From just repairing a floor to transom to stringers........FULL RESTORE

Thanks wood and yes ive looked at ur threads many many times. Great job with them.It makes it a lot easier for us rookies. I had an itch to use the grinding today wasnt really planning on it today. I started the day making adjustments on my cradle and didnt want to stop working once i started.Thats when the grinding started calling me. With the grinding how far down do i go? The area i did today i went down a little to much in one small spot but the rest looks all shiny.Thanks Kevin

Re: From just repairing a floor to transom to stringers........FULL RESTORE

Just need to grind to good smooth glass. I think you'll recognize it when you see it.

 

[oops!]

Re: From just repairing a floor to transom to stringers........FULL RESTORE

yep....as woodie said......

take out the transom till you reach the glass hull....

you can grind the wood out.....or use a hammer and chisel.
if the wood is still good in some areas.....stick the chisel between the wood and hull....and gently start prying it apart....the bond between the wood and the hull will start to break.,,,,,then just keep working it till the transom comes out.
any left over bits of wood on the glass hull can be ground out.

after all the wood is gone......you need to grind the inner skin so get any surface resins and contaminants off....
it is almost a scuff type grind.

after you are down to the bare glass......vacuum the whole boat and clean with acetone !

Re: From just repairing a floor to transom to stringers........FULL RESTORE

Finally got some more work on boat today.Decide to built a tent ova the boat so when it comes to the fiberglass curing ,dust,rain,etc. Its still in mid 50's to high 60's.Not there yet but hopefully soon.Still have more grinding to do.Plus made a quick rough draft and some templates.Just for refernce.Now for the questions lol.I notice i have some indents where the transom goes .Should i fill those up with filler before the transom goes in or will it be fine when i attach the transom with pb?Also does the transom have to be tabbed onto the cap?Looks like it will be a tight fit cause of the splashwell.Hopefull ill pick up some wood soon. I havent decided if im going with pt or ext.I usally start my season around the end of april.Not sure i wanna wait for some wood to dry.What do u guys think?Thanks. Kevin
