Stringer

[Big Fish]

I’m working on a 1977 Terry bassboat. All the stringers are rotten with just the fiberglass casing. I can’t find any marine plywood in my area and shipping for it is almost twice the cost of a sheet. Any suggestions on what kind of wood I can use. Only place to buy it is Lowe’s and I know not to use treated because the fiberglass will eventually separate from it. Thanks in advance , Fish head

The original stringers were made of regular plywood. They lasted 48 years. Any exterior grade plywood from Lowe's will be fine.

Thankyou for responded. When it quits raining here I will post pictures and probably more questions.

Or you can just laminate over the excisting ones if they are else ok. The core in stringers is just to make the form for them..

 

[Big Fish]

Unfortunately they are gone and the fiberglass they used to seal them seams to be of poor quality. Leaving lots of open voids.

I would add to gonzo's advice that you really ought to seal all the surfaces with a coat of resin before bonding the replacement plywood into the hull.

Will do ,

I’ve removed the floor and the 2x6 previous owner had put in attached to old stringers. lol. Don’t know how the boat even moved on water with all that weight . I’ve dug out wet foam and I’m now going to cut and grind out the fiberglass that encased the old stringers which are just wet powder.

I cut front cap off so I can get to stringers in front. Left 4inches around the perimeter so I can fasten a strip around it so I can drop back in and tab in.

I already have 2 gals of epoxy and wondering if this would be okay to make peanut butter with to tab in stringers or should I buy some other kind of resin like polyester

Bigfish, just double check with the rest of the guys, but it's my understanding that epoxy sticks to polyester resin but polyester resin doesn't stick to epoxy. So with my boat i am using only polyester resin and am making the equivalent of the peanut butter mix with that. Some filler and cut up chop strand mat

Polyester resin will adhere to epoxy. However, the bond of epoxy is stronger.

Ok thank you.

Twice I have had marine plywood shipped to me in Colorado from Noah's in eastern Canada without the cost being too great, but perhaps things have changed greatly in the past ten years.
