How to: Pouring & Installing a SeaCast Transom

Lets pour the SeaCast Transom!

[@billwallenstein3387]

5 years later; would you use it again? What would you do differently? Do you still have the boat? I’ve replaced a transom the original way, cut back the deck, the stringers, all from the inside. It seems the seacast cost is about 30% more. I used marine epoxy. It took me about 3 weeks after work in the evenings and weekends. How much time do you think you saved?

[@DanPlusWater]

Thanks for making this video. I'll end up having to replace my transom in the next year or 2. I know someone must have already asked this question, so I apologize for asking it again. With it being about 7 years now. How well is the transom holding up, and what size motor do you have on it? ( I am trying to gauge that against my boat which isvery similar in stern design ).... From Lansing, Michigan, hope you and everyone else have a great weekend.

[@wanting2sailssw256]

I'm out of the technology a bit. 30yrs ago. We only left the outer shell/skin and we started from that layering glass/resin,plywood,glass,resin, plywood,etc,etc That was on a 1970'ish 20ft Grady White. Its 2021 and that same transom is still solid to this day. But I will say, what your doing seems much easier and stronger, and I bet it last forever with no wood. Thanks man, learned a new way today.

[@bigkrypto]

Just wondering how this has worked out for you now that it's been a couple yrs . I live in Florida not to far from you and was wonder how it worked out for you doing it outside?

[@davekimbler2308]

So it’s been 5 years how’s it holding up ?

[@HouseMadeUS]

Solid! 👍🏻

[@fishnfreak18]

Nice vid. How has that transom held up?

[@HouseMadeUS]

Really good.

[@sunking2001]

It looks like the transom was way too thin/narrow to handle much load...unless you had a small motor mounted on it. I would have made the transom thicker for more strength.

[@boatworkstoday]

Awesome job Guys!

[@dieselyak4842]

What are your thoughts on this? With out having a way to get the air bubbles out is it not going to be weak from all of the voids?

[@adrianlowe20]

@@dieselyak4842 I would use something to vibrate it while pouring just like doing concrete.

[@kenhotaling7050]

You mention "$800 worth of product." If your transom wasn't curved like that, would you still use seacast or just marine plywood?

[@MikeFosterOutdoors]

How did you clean it out at the beginning. Did you use a saw or something?

[@HouseMadeUS]

I used a chainsaw.

[@gholdsfishing3144]

How good would this work if i cant get ALL of the rotted wood out? Couple bits and piece are still stuck on inside. Not much but some i cant get to. Would this form around it or is it too viscous

[@HouseMadeUS]

It will form around it. No worries, but get as much of it as you can removed.

[@bobbyboykin7137]

Two words: Drop Cloth

[@HouseMadeUS]

Yeah man, haha! 😁

[@L2fish]

I rebuilt my 59 Whitehouse from the inside. 3 layers of 1/2 marine plywood with a layer of chop strand in between each layer. One at a time clamped in place to attain the curvature. Then glassed over the plywood on the inside. Outside with gelcoat remained on the boat. I was thinking of that stuff but it was pricey

[@richarddewitt-lt7pl]

How did it turn out any probkems? What hp?

[@chrisweber4381]

Awesome job man! Good to see how well your craftsmanship and the product worked!

[@DumbCarGuy]

I'm quite sure poking it with a stick is just fine but like the big cement companies. They would use a vibrating rod but you can simply put a palm sander to the transom and watch the goo vibrate into shape.

[@Will-tm5bj]

I kept thinking the same thing

Great job, I do just love sat in the garden in good old cool England watching all your hard working boat restoration videos well done ...

[@HouseMadeUS]

I just read this! HA! Right!?

[@timsharpe3498]

SeaCast is great for an outboard transom but doing an inboard outboard transom with it can be very tricky. It's still well worth the extra effort.

[@Beachnative42]

when did it sink?

[@HouseMadeUS]

This one never did sink. It was just rotten from being old.

[@TheMadawg67]

I don't know sh't about boats, but I do know concrete and when you pour you always use a vibrator or a hammer and tap it to get the air bubbles out because they weaken the concrete but great vid and good job

[@HouseMadeUS]

Thank you Lee.

[@joebloe1401]

Janky? Sounds like you made that one up!

[@mrbigwyrm]

slow and steady wins the race

[@sylvestrepalacios7530]

Any updates on the seacast?

[@richt8297]

I would have used a palm sander and vibrated that transom while poring to get all the air out

[@HouseMadeUS]

Yeah that would have helped.

[@catsupchutney]

So about four years later, how did it go?

[@szapata9817]

Seacast $800 really Bros? That's a lot of money there charging people

[@HouseMadeUS]

You’re telling me!!

[@sailormanharry295]

I HAVE USED THIS SEACAST SEVERAL TIMES FOR TRANSOM AND STRINGER REPAIR AND IT IS A VERY GOOD PRODUCT. VERY STRONG. ON A WIDE EXPANSE I ALWAYS WOULD GLASS SOME MORE REINFORCEMENT ON THE INSIDE AS AN EXTRA PRECAUTION. BUT VERY VERY STRONG PRODUCT. LOVE THIS STUFF.

[@HouseMadeUS]

+SAILORMAN HARRY - 100% agree! Great product.

[@georgenettlesjr1466]

Lot of hard work but it pays off in the long run great job😊

[@HouseMadeUS]

Yes! Thank you!

[@Rick-tb4so]

I wonder how much air is trapped in it ??

[@SolarBurrito]

Like a boss! Eager to see more!

[@bwspacity]

I was told by an old guy. to use wax on the bolts

Yes that can also work.

[@fivehundreddollar7.3powers26]

I'm getting ready to do my 14ft bass boat and was getting a idea. I think 5 will get mine I hope.

[@HouseMadeUS]

+Dustin Mayfield - There is a calculation tool on the SeaCast website, I would encourage you to measure and do the math, my calculations were spot on. Good Luck!

[@Memo-nd6fj]

I replaced the transom same way you did on my 1987 Bayliner. I used long drill bits to remove most of the wood in the transom along with some large heavy screwdrivers to scrape the old glued on wood from the fiberglass walls. Designed a long hose to reach on down and vacuum out any residual wood and scraps. The transom was as hard as a rock and lasted the rest of the lifetime of that boat which was decades before it was junked. DIY not to hard. Going to redo the transom on my 1983 V20 that I just started worked on.

[@SonofGodly]

very good job kaapyton

[@joshgreenwell4499]

Doing a fine job Captain House!!

[@Rick-tb4so]

I think Carbon Bond would be better to use because its thinner to pour with fewer air bubbles. You don't have to use a stick to push it down.

[@gerardjones7881]

you made a mistake, When the seacast was wet you are supposed to apply glass cloth to the top surface and push the cloth down inside to encapsulate the core.. It prevents the sacast from cracking along to top edge. It also saves a ton of finish work. I sanded mine and painted it, no further glasswork needed. Then replaced the alum trim and it looked original.

[@svzigzag5898]

I give you a 9.789 on that dive. Looks great mate. Put in comments how it holds up!!!!!

[@HouseMadeUS]

Last time I saw it, it was solid. I’ll have to ask the guy I gave her to if she is coming along.

[@streetscapes]

@@HouseMadeUS Have you asked the guy? Lol

[@dannybranas2520]

3 years after I made the transom with Seacast it cracked...

[@bipedalhominid6815]

Wouldn't it make sense to make your funnel as wide as the transom for pouring the seacast into?

[@ryandodson2783]

Thanks for the video! How many gallons of seacast did you use? Thanks

[@alfredbuttery7548]

Did you send the back of the transom for a reason because of the heat that the chemical creates

[@dennisharrison4744]

Just decided to leave mine like it is some one recently put new Marine ply in it I poured epoxy in the top kinda spread the ply it's super strong now I put a brace inside of the boat that they left out the whole boat was redone floors are awesome in it they just had trouble with the transom

Good job!!!

[@danibryan89]

Great work. I have a 22' Grady White with a weak transom and this looks a lot easier than trying to replace with wood again. How is it coming along?

[@adamwood2813]

Great job! Your videos on this process were very helpful so thank you for taking the time to document it. I'm getting ready to undertake the same process on a 1963 17' whaler. What kind of grinding wheel were you using to remove the gel coat from the transom? I've been using flap disks but they leave a lot of gouges and swirls that have to be filled later. You seem to be using something different?

[@terryg9770]

Awesome work bud!

[@HouseMadeUS]

+terry gonzalez - Thank you so much! It wasn't as bad as I thought it would be.

[@chrishad95]

Good job man, I am really enjoying this series of videos. One thing that keeps coming to mind.... Would it make sense to put this project in a garage, like a car restoration to make the project take less time? I am even thinking some kind of portable air conditioner as well to make the temps while working more agreeable.

[@HouseMadeUS]

I would love to do that, but air conditioned space in Florida is expensive. Oh damn it do I wish I could afford that!!! Hahaha!

[@hkm_865]

Too bad that stuff is so expensive! I would redo my whole boat with it.

[@Transomrepair]

We haven't raised our cost for over 3 years. We works so hard to keep the cost (because we know so many hard working people haven't had a raise because of USA economy is still bad ), even though the ingredients have raised. We take every profit to keep our costs lower by purchasing larger amount so we can keep it low. It does cost alot for all the benefits. If you want a permanent replacement, ours is the only one. You get what you pay for.

[@ryancoke9]

Are all boats designed like that transom? I have a 15' anchor industries boat that's got a rotten transom on it, and I don't want to get rid of the boat.

[@HouseMadeUS]

If its a fiberglass boat its probably similar yes.

[@ryancoke9]

Thanks! I was going to try seacast, but I realized they don't sell it anywhere close to me, so I'll have to use wood I guess

[@toargames]

Just contact them via email. They will ship them but you need to pay the shipping costs

[@sailormanharry295]

I ALSO MADE MY OWN VERSION OF THIS WITH BONDO, RESIN, AND MILLED FIBER FOR SOME AREAS THAT I RAN OUT OF SEACAST AND IT WAS AS BULLET PROOF AS THE ORIGINAL SEACAST WAS. I HAVE EVEN THOUGHT OF EXPERIMENTING WITH MY OWN VERSION OF SEACAST FOR REPAIR WORK. SEACAST IS VERY EXPENSIVE BUT IT WORKS.

[@dennissytsma3561]

Florida neighbors are often crude and rude and figure they can do anything on their side of the fence they want to do and if anyone calls code enforcement war breaks out. Neighborhoods not stable with many rentals to snow birds or empty nesters who dream of retirement in Florida more there find it crowded and expensive and move again and again trying to find peace.
