I have a pretty good leak somewhere in the middle of my boat . I have a 79 charger mini day and my bilge came on every hour this weekend while it was sitting in the river . Not Gushing in but a steady trickle ...... I was planning on gel coating the boat this winter and really dont want to pull my subfloor and interior before summer, Could I get under the boat and try to locate the hole and fill it with 3m marine silicone?????? I know its a hole because the retard who owned the boat before me decided to use 2 1/2 tech screws to secure the seats . Thanks

pull the interior out and sit it in the water on the trailer and find out where the leak is coming from. worst case drill it clean and epoxy glass in a plug, sand it smooth on both sides and do a little touch up gel. dont wait or else you'll have to deal with water damage problems. =)

wow, your in a tough spot.... i dare say fill the boat with the water hose and go under it and see where it is leaking from. feather it back with a da and lay new glass or sea going poxy putty, glass would be best of course

I say do it right the first time ;) Here's my reason: After your fix seems to hold and get you through the remainder of the season, you might say screw it i'll run it another season, and in the mean time you are fatiguing "possibly" an area of a boat, and then something bad could happen...obviously you bought the boat from someone that did some hull damage, and just gave you their headache...i would fix it right the first time! you might miss 2 weekends of boating because of it, but that is like money in the bank, when you know it will hold, and fixed right!!!

Problem is i have a sub floor , and I wont be able to see where the leak is coming without pulling that out and the foam in between the stringers...... dammit !!!!

chances are if you have a subfloor with foam under it, its already rotten if theres a hole in the hull... have u tried tapping around with a hammer and listening for dull spots?

I'm just patching the holes I drilled to remove all of the foam in my boat. Mine did not have a hole in the boat, but the foam got wet from other things. In my opinion, the foam in your boat is likely soaked like mine was. It is also my opinion that the foam will "NEVER" dry out once it gets wet, and you should remove every bit that you can before your boat rotts and becomes unsafe.

Well not wanting to do anything half ass I pulled all the interior , and I found a Few holes that looked to be where the water was coming in . i poked around with a screwdriver to look for soft or rotten spots, but didnt find any , so whats the next step do I start tearing out the fiberglass ?? Here some pics

I wish I could post pics, but have not been able to. What I did, was took carefull measurments as not to hit any stringers, or crossmembers. Then I drilled Two 4 inch holes--just barely touching each other, and then cut out the "triangle" pieces left between the holes to create an oval shaped hole. That makes a large enough hole to get your arm and some type of scrapper in there and rip out the foam. I repeated this in several places, until I had all of the foam out. I am patching the holes now, and since the carpet came out without any damage, I can just glue it back down, and cover up everything! I will need to "finish off" the floor under the gas tank, and battery, as those areas don't have any carpet to cover up the patches in the floor. It was not fun, and my arms and wrists got pretty chewed up doing all this, but I guess it was worth it to save the boat from rotting to death. --Not to mention all the extra weight the wet foam added to the boat.

heres what i did. i started out with a dremel, figuring it was pretty easy to handle... but it just didnt have the balls to cut through the fiberglass to release the floor. so i switched up to a 4" angle grinder.

cut out the floor, pulled all of the rotten foam and wood, cleaned it all up. cleaned up all the edges, corners, and about 4" outwards with a sander where the new wood floor would sit so new glass would stick.

cut new floor from i think it was 5/8" plywood. i made sure to cut it VERY snug. then i pulled em all out and coated them all in a thin coat of resin to waterproof em. put down some epoxy into the channel where they sit in the hull and dropped em into place, put a bunch of heavy stuff on top of em. lastly i mixed up some resin with a little hardener, enough to give me some time to work with it. put down some glass mat and glassed down the entire floor, and outwards to the hull 4". then once i got everything coated i whipped up a hot batch of resin and layed it down quickly. it kicked VERY fast and the floor is SOLID. slapped down some carpet and good to go for a few more seasons.

After Pulling the interior , and weighing my 50 hour work weeks , I decided to have a shop do it . I really wanted to do it as I have worked with fiberglass alot when i raced a Class 7 truck . The guy quoted me a grand worst case scenario if he has to replace some stringers .I will stop by tomorrow after work and see what the damage looks like after the floors up . And i will post pics of progress. Thanks
