Yep, it most probably is factory, but not a stringer, just a hull stiffiner. I've seen them before, as a matter of fact the restore I'm doing now has them running inbetween the wood stringers.

Re: stringer question/ help!

the thing with my boat is that the foam that was in it gave it the strength but i have removed it and there is only a small center stringer in the boat.. the hull is really weak now and i thought if i used the cardbord tube and glassed it really thick it would give it the strength back with out having to replace the foam. i'd put altleast 4 of them in 2 on each side.. what do you think? if you look at my other post there is pictures of the boat there

This is a PRIME example of why you should keep ALL of your posts together. The moderator already merged your other two threads and now he will need to do it again. To answer your question IMHO this would NOT make your hull structurally sound. It was designed by the ENGINEERS at the factory to be the way it is and it should be put back the same way or Better. Your suggestion is NOT making better. Your boat was constructed as a foam reinforced hull. You need to restore it the same way or find another boat. We can and will help you do that if you decide that's what you want to do. You are correct about how they did it at the factory and thats how you will need to do it as well. Replace the transom, the stringer and the deck. Cut some Pour holes and use Pour foam to fill in under the deck. Lots of examples here on the forum on how to do that. Keep all of your posts in ONE thread.;)

Yes you can.. Cardboard is compatible with fiberglass. The fiberglass is going to be more support on the hull than anything else if done correctly..

I doubt your 15 footer has a much of a "stringer" system in it :). .. What ya got on that back end of that thing .? a 70 HP ? ( Although I have seen it ;) ) .

100 HP is way too many ponies for that rig....no one here will recommend it.

Tulkster,

There's a lot more to it than just bulking up the transom. The weight, torque and stresses that motor will put on that little boat, makes it totally unsafe to operate IMHO.

Re: stringer question/ help!

what is IMHO? with that motor you just cant hammer on it from a dead stop and more then 3/4 throttle gets scary

Re: stringer question/ help!

Okay....here's the thing about horse power ratings. It really doesn't have a lot to do with the actual strenght of the boat (some but not much) as it has to do with the overall performance. When a boat is way overpowered it can become very unstable at higher speeds.

The length of your boat has much to do with the power rating also, since the more wieght you have out front helps in the handling of the craft. I've been in boats rated for a 150, with 250's hanging on them and at high speeds the chine walk is terrible and very unsafe. This chine walk puts stress on the hull that is wasn't designed to handle.

We aren't saying that the larger HP will just sink the boat at all. It may be okay at certain speeds with an experienced operator, but for the average guy, it could be a disaster waiting to happen.

In all my restores over the years I've done boats rated at 125 up to 275 and the transoms are built the same, often the stringers are a bit heavier duty, but really not a lot of difference, the problem as I said is performance, for the most part it's just not safe.

If you want a high performance rig, there are plenty out there, so I'd suggest buying one that is rated for what you want it to do. The max HP on the rating plate is generally about 15% or so under what the factory has tested the craft at (a libility thing), so over rating slighty is probably okay, but rated 40 with a 100, just not a good idea.

If you want to overpower your craft that is your business, but personally all I can say is it's not safe and I (or anyone else here on this forum) is not going to say....."That's fine, go for it".

Insurance is also an issue, but the least of your worries if your dead from a boat wreck.

Re: stringer question/ help!

thats why i'm the only one who drives the boat and i dont drive like a retard and go super fast, its just nice to know that i have unlimited power when ever needed and where i live you dont need insurance on boats

Re: stringer question/ help!

Yup..using carboard and glass will work for your stringers.

But thats not your problem here..its that 100 ponys sittin on that weak transom !!

As others have said..its not safe without completely remodding the trans/hull system.

Sorry but .. I will not/cannot be apart of this thread or modding this with any advice due to Safety Reasons.

Good luck and stay safe !
