Bandaid OR proper burial? )))PICS(((

Out on the water today like most every Saturday I took more notice to the water I pump from the bilge. I began to notice on outings that the water would be dirty and start flowing right away. After a bit it would be empty, trolling for a while I then flip the switch and clear water comes out. This tells me it is fresh water from this trip. The water before had to have been from last weeks outing. Thinking back this has been the way it has been for a little while now. Though when going through the muscle inspections my bilge is bone dry! Kind of tricky, where is this water coming from? I pay it no more mind than usual and go about my trip. Loading up at New Hogan Lake I pulled my plug while level and very little water drains out the hole. I get a calm feeling until going up a hill while leaving and in my mirror I see a trail of water! I find a turn off, steep in grade and back down and look to my drain hole to find water flowing like a faucet. Where is the water coming from? I drop and start crawling under my boat a 1970 Glastron TriHull model 156. What I found has me worried, a bolt poking through the bottom and a nice size crack in the hull right next to the bolt hole!!!! I have no clue what to do. The floor needs a little work and this hull damage is directly above the weak spot in my floor, the passenger seat. I bought this hull for a cheap price knowing I was to fix the floor in the off season and was even going to seacast the transom as a preventive repair issue. The boat is great for me and my family, wife and 2 kids. We have room to fish, ride around, and we were getting ready to purchase tubes and wake boards. My motor is solid, a 85 horse that pushes the boat along around 40 mph, gps. Is this a major shut down operation until further notice repair. Or can I seal the hole and crack with some 3M and deal with it when I plan on doing the rest of my work. Better yet should I cut loses before I get to deep and cant afford to get out of it? That is my main concern, I dont want to bite off more than I can chew. I am handy with tools and have the knack to fix just about anything. I just dont want to shut down for 2 weeks and take care of this during the summer, whole reason for owning a boat! lol Please help with thoughts I can and will take the bad right along with the good so dont hold back or try to sugar coat my options. I need to know what you all think. I value the opinions, I can tell myself what I want to hear. But coming from those who know it is hard to turn a cheek and go against the grain.

thanks,
cordell

Re: Bandaid OR proper burial? )))PICS(((

I already did that, lol. In fact it is not as bad as I thought it was. The flooring is rotted from weathering in someones backyard under a tree. I cleaned out leaves and twigs for hours on end. Anyway I removed the seat and proceeded to cut the carpet to find flakes of wet plywood, I tore away and found the hull and the screw/bolt that held the seat in place, but found a new home in my hull as the floor was not there. Removing that was easy and I now have 3M 5200 in its place. I decided I am going to do the floor now. The foam is not soaked as I thought and the stringers are strong! I only checked a 3 foot by 3 foot section but this is where the floor is weakest. The crack appears to be in a gel coat material only as I can not locate it from the inside. I will still reinforce this area while the floor is out. My concern is attaching the new decking. I have a drawing here that shows the deck laying on the hull and the only 2 stringers that I can see for now running lengthwise with the boat. Where the deck meats the walls how do I attach the decking to the hull? I am thinking liquid nails or some sort of construction adhesive. My other concern or question is do I need to fiberglass the new decking? What will happen if I don't and are there any other alternatives to doing this? I have a 3 day weekend next week and believe I can knock this little project out if all goes well. I already bought the carpet as I knew this was a job coming up. Are there any other things I should be aware of? I would hate to get into this and find out I am going about this all wrong!

thanks,
cordell

my drawing is not the best LOL

Re: Bandaid OR proper burial? )))PICS(((

well, think about this, can you patch the hole, drop a 3/4 or 1/2 inch plywood on your current deck, bolt your seats and finish the season? That is what I would do then later during off season I would take it down and do the job. Believe me, unless you have lots of time off, the proper tools and the know how it will take you a bit more than 2 weeks to finish it up properly. For example, the wood that you will use for the deck has to be dried. Most of the wood you buy in most hardware stores is not dry. Drying it will take a couple of months... You migth want to buy the plywood now and set it to dry and make sure it dont warp.

Either way you go I would not sugest you scrape the boat. You say it is the perfect boat for your needs. That is very hard to beat. Have fun!

Do a temp repair using glass not 5200,you'll have a fine time trying to remove 5200 from wherever you glopped it on, go to a marine store and buy a West System repair pack,as suggested above,drop in a temp floor,paint the plywood ,boat for the season,then tear it all apart off season.

It all depends on how much money you have to invest. If it were me, I'd:
1. pull the floor up
2. remove the bolt from the hull
3. tape over the hole from the outside (the smoother the tape is, the smoother the outside hull finish will be)
4. use a fiberglass mat/resin patch on the inside
5. let it cure
6. remove duct tape and sand smooth
7. cover it with some cheap paint (actually I'd probably just leave it unpainted, but that's just me)
8. get some MARINE plywood and coat BOTH sides with epoxy resin
9. let cure
10. use thickened epoxy to "glue" the floor down onto the stringers/hull
11. let cure
12. paint floor or cover with marine carpet


This would let you enjoy the boat for quite a few seasons without worrying about the floor or the hole in the hull.

Re: Bandaid OR proper burial? )))PICS(((

I already gooped the 5200 on the outside:(, the screw removed quite easy once I tore open the deck. The crack seems as if it in not all the way through, would it be some sort of gelcoat on my hull? I do want to reinforce this area with glass from the inside regardless. I am torn between the temp or the full fix. I know I can tear out and fit plywood in one day. The worrisome part is the glass work, ie dry times and the spreading of it. I can spread drywall mud and stucco if it is anything close to this I will be fine. Once my new deck is glued down do I need to glass a thin layer over the deck, or can I just prime the deck with something like KILLS (primer) before I lay the new carpet? I gave up on the lakes around here until after fathers day when I get a downrigger :] So that gives me a little time to get this done. I appreciate all the reply's so far, Thanks!

I think I would use marine-tex instead of fiberglass. Good and strong and easy to work with. I believe you can still use the fiberglass mat with marine-tex.

Cordell, one of my favorite quick way to fix a hole or a crack is with marinetex. It is really hard to beat. If you want to "properly" patch that hole read this article: http://www.boatus.com/boattech/casey/17.htm. I suggest you read the restoration forum so you can understand what you are potentially getting into. I still say put a bandaid and then fix it properly during your off season. BTW, let us know where you boat. Sometimes that make a world of difference when giving advise.

Re: Bandaid OR proper burial? )))PICS(((

Thanks for everyones input I have decided to do the job right the first time. I cant see buying plywood and then having to buy plywood again in 4 months. Like I stated before I have the carpet already so a few materials is all I will need ( i hope ). Anyway I will be starting a new thread in boat restoration for help with this project that I plan to get done in 3 days if all goes well. I am not familiar with cure times on glass so that might be shot before I even start. lol This morning I have gotten the carpet up and am going back out to demo the floor, this is the fun part! Thanks for all the help and look for me in restoration later this evening. I am taking progress pics as I go.:)

Re: Bandaid OR proper burial? )))PICS(((

You know after taking into consideration and factoring in some of life's set backs I have figured a new time frame. I have 3 days before I get back to work and then work 4 and have another 3 off. 2 weeks of working on the boat will have me on the water on the third! :) I forgot about the wife and 2 kids , oh yeah I have to take time t eat and sleep also. LOL
