Re: Restoration project

oh yeah.. almost forgot. Looks like the boat isn't on the trailer forward enough (agree with recent post) Seems like it can go forward quite a bit. Those fenders are pretty damn cool lookin...

Re: Restoration project

I think Dave JZ is right about the holes in the bow. The close up pic shows what looks to be a running or marker light bezzel from a truck. Probably wanted them for additional running or docking lights.<br /><br />There are some really cool dress up parts on that boat that are definatelly not factory MFG parts. Probably added by the dealer or maybe the owner. Keep those parts! I might even want to make a mould of some of those parts for myself! Let me know if you need the MFG emblems or not. I will be casting a few more over this winter.<br /><br />Keep on striping it down to bare hull then work it back up to restored condition. That's the best way to do it. Trying to work around stuff just makes it harder in the long run. I found ziplock bags come in handy to store nuts/bolts/hardware and keep it organized in cardboard boxes. <br /><br />Keep up the good work. You can't buy a boat like that new for any price. So don't be afraid to spend a few bucks on making it look nice. They are truly fun boats and the handling is outragous!

Re: Restoration project

Yeah, I'm not gonna put lights in... the spot light is enough I think. I'm just gonna reglass or bondo or whatever it takes to fix those holes. <br /><br />As for the trailer, lotsa work to be done there. Just picked up some 2x4s to build a rack to hold the boat while I work on the trailer. <br /><br />Last night, we pulled out the seats, removed the floor (really thin splinters of plywood, thats it.) There are (I think) aluminum stringers bolted to the thick ribbed fiberglass. Kinda interesting... extremely solid. We also removed most of the hardware (except the thru-bolted stuff that was hard to get to... that comes out tonight.) <br /><br />Mark42: I'll catalogue all of the metal bits, and send pictures to you. Anything you want to make a cast of, I'll send on over to you.<br /><br />Thanks for all the help/support guys! I'll keep posting my progress when I have time.

All I have to say is good luck I just got mostly finished with my 72 larson tri hull its my first boat and I bought it cause it was cheap..That is until I got it home and started working on it.

I do however have a 72 50hp johnson that I got with my boat, Put on a 85hp mo power..I dont think it wieghs more than 200lbs or so being as I can prety well move it by myself..Let me no if youre interested..And good luck..

Re: Restoration project

I have seen those cleats available new. Just look around the suppliers, I think they are fairly easy to find.<br /><br />So you have the pre-fiberglass aluminum stringers. Pretty good. All you need is new plywood. Congratuations! You have just saved a month of Sundays working on strings!

Re: Restoration project

Super cool. A few quick questions though... How should I go about attaching the plywood? Do I need to attach it? Do I need marine-grade plywood, or can I get away with exterior grade? I've read some threads about the type of plywood to use, but it is so easy to do the floor in this boat... nothing to be glassed in. My plan was to put in exterior grade wood soaked with lots of epoxy sealant, and painted with that non-slip gritty paint stuff.

Re: Restoration project

For the floor, you can use exterior grade ply or marine ply (my preference is 6mm Meranti ply). Look for good plywood. Too often, the exterior stuff has only 3 laminations and the middle is some really soft junk. <br /><br />Definitely coat all surfaces with at least 2 coats of epoxy. You will know when you are done when you look down the surface (at an angle) and see a 100% glossy finish. Any non-glossy areas need more epoxy. Usually, 2 good coats is all that is needed. <br /><br />If the surfaces that the floor sit on are fiberglass covered, then you can use epoxy (mixed with a filler like woodflour or silica) to bond the the bottom of the new floor to the boat. If your stringers are aluminum as mentioned in an above post, I would use a good polyurethane adheasive like 3m 5200. <br /><br />On the top side of the floor, bond the floor to the hull sides with 2 laminations of biaxial fiberglass strips (the first 3" wide and the second 5" wide). <br /><br />Download the epoxy how-to book from SystemThree or other epoxy manufacturers. The booklet shows you how to make fillets, saturate glass, and a lot more. On the SystemThree site, you register for free and then you can access the book. I believe West System and Raka also have free how-to booklets.<br /><br /> http://www.systemthree.com

Re: Restoration project

How was the orignal floor attached? Was it treated plywood? What type of finish would have been on it?

Re: Restoration project

The original floor was 1/4 inch ply-splinters ;) Seriously, it looked like plain-jane 1/4 inch 3-ply plywood. It wasn't strong enough to hold my weight when I first stepped inside, if that tells you anything.<br /><br />I was looking more closely at the aluminum stringers, and noticed that there are screws that held the old wood down. I may just go that route. The wood was never glassed to the hull, instead there were just rubber strips that fit snug along the wood-hull border. I kinda like this A) because it was super-easy to get the floor out and B) it will be super-easy to put back in.<br /><br />Something odd I noticed though, there are 3 aluminum stringers, and ribs in the fiberglass hull on which the wood sits. However, middle stringer seems to be a little taller than the two side stringers. I don't think the wood originally sat on the two outside stringers. Rather, it set on the middle stringer, and the ribs in the hull. I might need to add some thickness (1/8 inch or so) to the side stringers to level them with the middle stringer.<br /><br />I'll try to get some more detailed pictures up tonight if that'll help.

Re: Restoration project

It it possible that the hull sagged a bit, allowing it to actually bow? I haven't rebuilt enough boats to have seen it happen. Most of boatbuilding is common sense, though, and I'm trying to apply some. :)

Re: Restoration project

Yeah, I thought about that, but I don't know why it would sag evenly on the two sides and not in the middle. I guess it's kinda hard to know for sure without looking at it in person.

Re: Restoration project

Can anyone suggest the best method for taking paint off the hull? This boat has been painted white, and will need repainted. Would you recommend a solvent first, or just sanding? <br /><br />For the topshell, I'm going to sand/grind all of the holes/cracks/etc and bondo them, then repaint it bright red.<br /><br />As for the paint, I was considering Top Secret Coatings or something similar. Any thoughts? The boat will be trailered when not in use, so I intend to repaint the hull (not re-gelcoating... too much work.)

Re: Restoration project

gex: A hull may sag like that if it was supported properly on the trailer. If the trailer had keel rollers down the middle and the side bunks were not properly adusted, the hull shape could change over time as the internal boat supports rotted. I have seen some hulls get some strange shapes after sitting a long time on a trailer. Just a theory. I would make them level again before installing the new floor. Some boat stands pushing up slightly on the chines should do it.<br /><br />Regarding the paint. The Top Secret paint doesn't look any different than any other 1 part marine paint (ex: Petit easypoxy, Interlux brightsides, etc.). These paints are good and very easy to apply. They don't get as hard as 2-part marine paints and 1-part paints may need repainting early than 2-part paints. Whatever you choose to use, make sure you use the specific primer for that paint.

Re: Restoration project

Regarding the sagging, I looked at it last night, and where the stringers mount to the transom, they are not in line... i.e. - the middle one is mounted higher than the other two... so it seems this was done intentionally. The front seat mounted only to the two lower side stringers (through holes cut in the wood floor.)<br /><br />None of it makes any sense to me. I'm going to add something to the side stringers to level them with the center one so the floor will be supported by all three. <br /><br />Note: I believe the floor was originally only supported by the center stringer, and the ridges in the side of the hull (which, if you could look at it, seems adequate enough.)

Re: Restoration project

Mark42: if you see this... did you replace your rub rail inserts, and if so, where did you get the inserts? I noticed yours are black, weren't they originally white? Also, I may need a few of those arrow end-caps... do you have any extras left?<br /><br />All: I want to keep my existing steering wheel, but it is in pretty bad shape... It is some kind of plastic I think, and it has some pretty bad cracks. Do you think I can repair this with epoxy/sand/paint?

Yes, I did replace the insert. It's fairly cheap, about $24 for 50ft roll. The insert was black, so I replaced it with black. This is best done on a nice warm day because the vinyl is much easier to work with. Good idea to remove all vinyl, then its easy to remove the screws holding on the aluminum to straighten and bent areas. Don't forget to go around and tighten all the screws, almost all of them took half or 3/4 turn as I worked my way around the boat. I can't find a reciept for where I bought it, but I remember seeing it at multiple marine parts suppliers. <br /><br />I can get you a set of the rail ends. Post an email where I can reach you.<br /><br />Regarding the wheel, check out the auto restoration suppliers for a wheel repair kit. It is basically epoxy and fillers that work with old plastic wheels. I did an old car wheel by sanding, filled cracks with regular 2 part epoxy from hardware store and painted with epoxy spray. Held up very well.

Re: Restoration project

BTW, does this picture look like what the floor in your MFG is like ? The floor in this pic look like the sides are very open so any water coming in would run right off and into the bilge.<br /><br />From you're description, it sounded to me like this is the design of your floor. Is it close?<br /><br />
