I bought my SN last year. The previous owner did some pretty stupid stuff (I'm finding out more as I go). In his attempt to fix the loose screws in the driver seat mount, he used a longer screw on starboard side than the original. Guess what, he ran it through the hull.  When he noticed his error, he took it out and just replaced it with a shorter screw. When I found the hole, I put some waterproof tape over it and went with it. The tape stayed on through last season and is still on there now.I SWEAR...I DID NOT DO THIS. (I know what you are thinking). Now its time to fix it. So I have to: 1. Take out the driver seat. 2. cut the carpet. 3. Cut the floor. 4. Remove the foam under the floor. 5. Patch the hole from the inside. (resin and glass) 6. Fix the gel coat on the outside. A few questions. Is there an easier way to fix this? When I remove the foam, do I have to put it back in? Is is there for just floatation, or does it add some structural strength? Polyester resin would work fine here.... right? |

Just get some epoxy and a squeegee (auto putty applicator) and push it in from the outside. Then finish with some gel repair. This won't fix the rotted wood in the floor which is probably why the screws would not hold. |

I agree with Paul, but Id use thickened epoxy resin instead of straight epoxy. Use a high strength filler, like milled fiber. Shove as much in there as possible, then put some tape over it to keep it from running out. Once dry, sand it flat and commence with the gel repair, if youre really concerned with how it looks. It would function just fine without the gel though. ------------- |

I'm just concerned about not getting a good seal/bond if I repair it from the outside. Should I make the hole a little larger (I know that sounds crazy). The hole is sort-of small now, not sure that I can force much up insided there. What about filling a syringe with epoxy and squirting that up in there? Then covering the bottom side with tape so it wont run out. Let cure and remove tape. I'm new at doing this. Where could I pick up some milled fiberglass? Where is a good place to get fiberglass/resin/gelcoat... stuff like that? Found this place (fiberglasssupply.com). Do they have good prices? |

It will be harder to get epoxy to fill the entire hole without running out, and it will not be as strong as a thickened resin (assuming you use a high strength filler, as recommended). I would clean up the hole from the bottom before starting. Get any loose glass/gel out of the way before you start. Ideally, you would glass the back side (inside) first, but I dont think I would tear up the carpet, floor and foam of a boat to patch such a small hole. ------------- |

Clean it out with a small file followed by sandpaper. I usually put thickened resin in a ziplock bag and cut the corner out... works just like pastry bag with frosting! ------------- |

Get a small diameter wire, screw, or cut off nail that fits the hole closely. Mix your epoxy very thick - I just manually cut up some glass cloth for such a repair & mix it in. Put tape over the hole & then pierce it with your screw/nail. Proceed with stuffing the hole with your very thick mixture, this is the tricky part, takes some patience, the mash wants to stick to my glove more than the boat! After filling maybe you can plug it with a slightly larger nail to keep it from running out. You will have to give it several coats to fill level. Sand it smooth & touch up with some matching paint. Edit - Or Gel if you want originality! ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

If the resin is thickened to the consistency of peanut butter, no worries on it running out of the hole immediately. It would seep out over time, but thats what the tape is for. One quick application is all you need. ------------- |

I'd go after the hole with a small burr and the Dremel. Since the hole is old, who knows whats in it - mold? Maybe even some oil got up that far? You want to get to clean glass. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

get a pan head screw, dab some 5200 on it and drive it from the bottom. Fixed! : ) Just kidding, use thickened epoxy. Coat the hole with straight thin epoxy, then thicken some and fill it. Oh and don't feel bad. I know a guy who couldn't get his boat off the trailer no matter how hard he gassed it in reverse and jerked the truck back and forth. Turns out he had some of those long screws you used and drove them through the hull and into the bunks. Oh well... ------------- Jesus was a bare-footer............. |

Tony, Let me fill you in a little about the Marine Tex. I consider it one of those "do it all" products that is made for the backyard DIY'r. I wouldn't be surprised to see it advertised in an infomercial. The biggest issue is it's a premix. This does not allow you to prime a repair area with a straight epoxy which with it's lower viscosity will soak into the base material. I have seen "repairs" fall out of hulls! It's also filled with a low strength filler so it goes on smooth. (the DIY'r again) The hardness simply comes from the epoxy resin. Unlike gel, Marine Tex is also VERY porous. (most likely from the filler they use) This makes it stain very easily. Stick with straight epoxy and have several types of fillers on hand. This way you can mix a batch for the specific purpose. IE: from high strength all the way down to easy sanding fairing. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Thanks for the tips guys, sounds like something I can do from the bottom side now. Question about what you all are calling epoxy. Are ya'll talking about epoxy resin or could I use the Devcon 30min epoxy (glue) with some glass cut up and mixed with it?  If not could you tell me the name of the epoxy. I'm new at doing this kind of repairs |

You can use that as is for the primer coat in the hole and for the filler, you'll need to chop up some glass pretty fine. The better solution is to get a small kit (I think it's quart of rsin and a 1/4 pint of hardener) of epoxy and a few fillers as well as a set of metering pumps. Keep it arond the house. I'd say a month doesn't go by where I don't pull my epoxy out and mix up a batch for a project. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

After reading through again I have to apologize to Kirk but I was having a bad day. Kirk don't be afraid to ask questions sometimes we can get a little facetious with our replies. Baitkiller, I know what you meant  |
