If you made hour long videos we would still watch because they are so educational you are the man Joe

[@shananagen09]

The longer format videos are by far my favorite. Having something to watch for an hour and change that I actually enjoy is perfect.

[@doug2202]

Without a doubt the best boat build how to videos on you tube. You’re a great teacher.

[@kirkpierce3089]

Your dad would be proud. He taught y’all well and in return you are teaching all of us well, thanks Capt. Joe!

[@Micington]

Your channel is pumping congratulations mate! I’d say it’s because you’re a pro

[@FishBumpTV]

Wow, thanks so much! I appreciate the kind words!

[@countryracer69]

I like to learn every day. I learned from several places like Andy at Boatworks, my hydroplane building friends,and a somewhat local boatshop. Done several transoms myself with good success. But I learned a new trick or 2 here today. And one is gonna solve an issue with the jet boat transom I'm about to do. I built my clamps! More like overbuilt lol. Thank you for the knowledge! Hope you bought the cameraman a cold pop!

[@mchristofas]

Captain Busy Joe Buskens! Legend!!! Keep up the great work sir!!

[@FishBumpTV]

You're very kind! I'm glad you like the video.

[@ewjorgy]

Hi Captain Joe! Wow! Excellent tips in this episode! You have - BY FAR - the best fiberglass repair content on KZbin! I can't express how much I appreciate you sharing your knowledge and experience with all of us DIY'ers! I can't wait to see part 2! Take care and all the best from California!🧡

[@rogerhodges7656]

I really enjoy your presentation.

[@keithridlen7122]

YEAHHH the video I've been waiting for!!!!

[@108hindu]

Joe you remind me of my dad. Working out in the boat shop till after dark. 🙂

[@calvinallen4103]

This is exactly the video I have been looking forward to seeing. Setting the new transom is the next step in my flats boat restoration. Thanks

[@gregorymacneil2836]

Best Channel for fibreglass and epoxy! I always learn something. A pleasure to watch your channel.

[@FishBumpTV]

Wow, thanks so much for taking the time to watch and comment!

[@JackieKraft]

I finally went out of my way to try Fiberglass Warehouse, Highly recommended 😊

[@FiberglassWarehouse]

Thanks for trying us out!

[@jimclark2824]

I'd like to say I watch your videos to learn to build a boat. But what I'm really here for is to see you get something on your shirt 😂

[@karinvail]

I wish I would have had this video when we rebuilt the transom on our boat this last spring. Great video's, keep them coming!

[@karinvail]

we did use Coosa at least - it was $500 for a 3/4'' sheet locally to us!

[@FishBumpTV]

Glad to hear that you are enjoying the videos, thanks for taking the time to watch and comment!

[@FishBumpTV]

Its hard to go wrong with Coosa board! Thanks for sharing your experience with the channel!

[@allenclark1914]

I certainly appreciate your videos and the time you invest, and believe that you are the absolute best on U Tube for teaching all of us non professionals. I have repairs screw holes and a big whiskey ding on the edge of the anchor locker on my boat. I had my I pad with me and watched them did some work, then watched again and did more and repeated until it actually came out way better than i expected, you lessons really work, Thank you Captain Joe and a big thanks to your camera man Logan, he does an excellent job of getting close in there so we all can see exactly what your doing.

[@404unimog406]

VERY timely! I will be doing this shortly. Your tips on polishing old gel coat were a lifesaver on my old boat that sat for 44 years in the desert. It turned out great. Unbelievable really. Thank you!

[@nolinovio6748]

I’m about ready to do my transom also, glad to see those clamps and how they’re made…awesome and thank you

[@DondiTrent]

Capt Joe fish bump family Thankful for your time and sharing long video content it has changed my total fiberglassing experience y'all are doing a very good thing many blessings Fish bump family!

[@StubGKG]

Another awesome video, Thanks Joe. I very much appreciate all the effort that goes into making them. Personally I wouldn't mind if they were 2 hours, there's no filler in your videos, it's all valuable. I've been waiting to see you do a transom. Now I'll feel much more confident if I find a good deal on a project boat.

[@mitchelllavalley3497]

As l get older l never get tired of learning especially when it comes to working on a situation such as my own boat even tho l am not going to be getting as deep as you will with this project. Yet all the tips that relate to the materials you are using and the way you prep the fiberglass, the amount of vinyl ester to mix up adds up to the project coming out with a beautiful result! Yes Joe l really appreciate the many hour it took you to provide us with a shorten version knowing we will most likely need to expect that l will have to put in all the prep work if l want my boat to look good! Thanks Joe!

[@frankschannel2642]

GREAT!

[@joostsmit906]

Thanks to your channel i learned a lot about fiberglass work

[@WilliamGushulak]

Thanks!

[@jetson328]

Your videos are the best in class on youtube Thank You

[@benmac1395]

Great video as always! Keep them coming, they’re gold mines of information.

[@stuartlane7107]

As always, excellent content. Thanks, Captain Joe and Logan.

[@c.a.mcneil7599]

Thank you for sharing your knowledge. Great information and nicely edited

[@jeffandrews-lb8hz]

Do you ever use sea flex cloth ?

[@kylepaul2543]

I’ve been holding out on laminating mine in until I seen this video!! Cannot wait for the next vid so I can get crackin on mine! I’m using vinylester, csm, biax and multiple layers of ply as I have a curve in my transom that it needs to conform too so not sure how I’ll clamp it yet but still this helps!! Hopefully with all I’ve learned it’ll be strong Watched every vid on your channel and learning so much, they actually made me stop stressing and got me to make the first cut so please keep these long vids and tips coming 👌

[@copperheadmarine]

Tape, also something I wish I had thought of.

[@peterpapadimitriou7744]

Excellent more tips - I am leaning towards vinyl polyester I also love the prep fibre cloth markings from chopped to woven type - also those screws on the prep coat bench - never thought of that - thanks from down under

[@johnlove4183]

So well explained. thanks

[@luisherrera8296]

That’s awesome man we just put a new coosa transome on are Seevee 25’ wish I saw your vedio, before we paid a guy could of saved a lot. Thanks for your vedio’s here appreciate your work and teaching us all. Merry Christmas to you and your family Capt. joe 🎄

[@robertsowell7514]

Loved it. Thanks. I appreciate the content

[@xman6717]

I have a Glastex 14 ft. Boat. I will be restoring it.....but....is it possible to replace the transom, without.....taking the top of the boat off???

[@scottf6604]

Outstanding!

[@jtwalukiewicz4100]

Great video thank you!

[@davewheeler5850]

Thanks very much again to you both for taking the time to make these videos, you guys are absolute legends 🏆it makes my day when I see you guys have uploaded a new video. I’m really enjoying this project boat, wonder what postage would be to Australia 🤔👍🇦🇺

[@RickRick-bj1zy]

Great video

[@MrOddball13]

👍

[@hecdc305]

Just keep doing your videos like you have been. They have been very informative and useful teachings for the DIY community. If it ain't broke don't fix it. Could you laminate the 2 pieces of Coosa together, let it set, and then laminate them to the transom? Thanks for the video.

[@ChoppazOG]

💪💪💪

[@skilletojones2005]

Awesome! Thanks for making these videos! Do you think you might get around to making an I/O transom video?

[@NORSEMAN715]

This is great! What's the ambient temp in the room there?

[@williamfreret6859]

Another great video! I'm not concerned by boats but cars but is there so much difference in the approach when we speak composites? We can see that preparation (cutting panels, fiberglass, pre-fitting, marking and so on...) is the most important part of the work, time consuming but so crucial for the final result when it's time to put the final touch meaning applying the resin. I'm always impress how you speak so easily when you put the resin...perso I can't 😄

[@kapenakanaiaupuni5816]

It's not long it's perfect

[@jimp.7286]

Sorry if this is slightly off-topic but it does relate; if someone converts an older i/o drive to outboard bracket as I've been seeing some folks do online, what does that mean to the strength of the rear of the boat? Not just the transom. You're sticking the weight of the outboard even further back beyond the transom. Using plumber's logic,.. loads are transferred from the transom to the hull itself and isn't leverage increased? l like the idea of brackets on such craft but if they aren't designed for it,...............

[@Cameron-ur2tk]

I've done it but it was a smaller 18 foot boat that had an old blown I/O. The boat ran great and wasn't stern heavy after the conversion. The I/O was way heavier than the outboard I hung on it so even with the minimal extension off the transom from the jack plate it wasn't an issue as far as the boat sitting correctly. In my situation the transom was rotted out so I rebuilt the transom more beefy and tied it into the stringers/ floor and It was solid. I was more concerned about the weight being moved and balanced and how the boat sits and rides. Many boats have outboards so making it strong enough wasn't an issue but rather will the boat perform as it was designed to. I just went around and measured some peoples transom thickness, you can also google there boat and see what the manufacture rates there transom HP at whether its rated for twins and just use your best judgement as far as transom thickness and work required. Some people use the armstrong bracket which basically hull extension and has floatation built into it too, there's options but whether it worth your time and money is the other question or just buy something that was designed for outboards.

[@jimp.7286]

@@Cameron-ur2tk Wow. Thanks for detailed explanation. You said; "I rebuilt the transom more beefy and tied it into the stringers/ floor and It was solid." That's what I was thinking. Tying the transom to the stringers - just in case. I read of one guy suffering floor flex with the outboard conversion because it hadn't been tied in correctly. It's a great idea in our opinion and it puts a lot of older boats back into service. I/O's are o-k but have their problems, (don't ask how I know, lol),. Thanks again. Cheers.

[@Cameron-ur2tk]

@@jimp.7286 That boat I/O coversion the transom looked similar to this videos boat transom but full height. I ended up doing 2 layer of 3/4 ply to bring it up flush with everything else glassed it all in and then added an an additional piece spanning the entire transom from side to side. The 2 things that threw me off was the old outboard i put on it was a mechanical cable to steer it, getting the geometry wasnt going to work without being a huge pain so i just went to hydraulic and bought a seastar system and retrofittted it which is much nicer than cable steer. The other thing to consider is how far the outboard can tilt up and not interfere / hit the back of transom. Might need to cut it down or create a splashwell so the outboard can tilt up all the way so it can lock into place or factor that in if your going to use a jack plate.

[@jimp.7286]

@@Cameron-ur2tk I hadn't thought about hitting the transom tilted up nor the steering. Create a splash well, (but possibly a small one),. One thing I failed to mention,..I'm in the pacific northwest. The ocean can get pretty rough up north - hulls get smacked around. I pictured the outboard hanging out back there and being rough on the mounting points. I knew more and more people were doing it but wasn't sure it'd fit my mission profile. That was why I was asking in the first place. You've given me much to think about. Really appreciate it. Cheers again. 👍👍

[@86OEd]

👍👍👍

[@billygoins475]

Did you consider using Bluewater 32? Got any feelings on whether it would be better for a transom?
