The first metal thru-hull threads seem to have more of a bright yellowish color to them, indicating brass, rather than a slightly more brownish color typical of bronze. The valve and NPS(?) assembly at 2:22 also look substantially corroded with copper leach-out indicating brass. Finally, the cheap handle on the ball valve typically wouldn't be found on a much more expensive bronze assembly, only on a cheap brass one. That leads me to believe you have got a brass problem, not bronze. It would be good to section the removed valves with a saw to check for pinkish core metal indicating zinc loss typical of brass in sea water.

The step wrench is not for tightening or loosening!.. you hold the sucker stationary while the wrench on the inside does the work. Cutting the putty is fine, but a block of wood and a hammer breaks it out with no gouging the hull by prying.

Time proven is good, but that doesn't mean there isn't something better that exists now. Marelon won't corrode and adding seacocks with the fiberglass backing plate is a significantly stronger solution than what we had perviously.

Not quite following what the technique here is for torquing those through-hulls? Did I misunderstand your approach, that you didn't want to torque them all the way down because you wanted a sealant gap between through-hull and hull, just letting a small amount of the sealant "squeeze-out"? Is that a recommended process? What should those through-hulls be torqued too? Can't imagine your technique here is correct.

Very nice work!

I can't believe you called this an upgrade. bronze is much stronger and has a much longer life. Plus the insurance will not go for this. I have an Offshore 48 with twin Cat 3208s 1988 all seacocks and thu hulls are bronze. when properly maintained they all work great. I am curious what gave you the idea to go to marelon?

There must be a good reason that so many go for Tru-design composite these days and not bronze.

So totally complicated. KISS for me.

Step wrench: do they make different ones for metric and imperial? "Kittyhair": I have not seen anyone else use this stuff before. The only images you show are of the back of the can. Is it a filler? Can you tell us more about this product and whether you have used it anywhere else? Seacocks: can you tell us why you chose that brand / model? They are clearly beefier that the FP factory installed models, but it looks like a lot of plastic to go into some small spaces. Are they Marelon too? See you both in Annapolis!

@OutChasingStars

Жыл бұрын

I know there are various manufacturers of step wrenches, but not sure about imperial vs metric. Kitty Hair is a fiberglass filler by Evercoat that was suggested as a backing plate mount product in the Marine How To article. We'd never used it before and decided it would work better to mount backing plates without the center hole already drilled. It wasn't quite as 'spreadable' around the hole which made threading the thru-hole in during our "leveling" step harder. The entire seacock/thru-hull assembly is Marelon. And we went with their special OEM series which is used by boatbuilders. This is the most compact solution they offer but any seacock will definitely be bigger than what FP does from the factory!

Huh. Never seen anybody remove a thruhull like that. Always ground the outside flange down and popped it thru….

Easier to cut off the inside of the thru hull with an oscillating saw and tap it out from the inside . I don’t like using heat near gel coat. Personally I prefer the New Zealand Tru Design thru hulls and stopcocks. Leopard use 2 inch forespar ones on our toilet outlets and down the road they always seem to drip from the handle. You need to take the handle off and change the o ring and silicone grease it well and put them together again. I have not as yet had a drip from the Tru design ones. As you are using marelon you could have epoxied them in place. Certainly better than sika long term. I did that to my boat. One day if the need changing you just use the hole saw .

Looks like you started quite the debate on bronze vs Marlon and a sub debate on whether your old fittings were brass or bronze. Great video! I recall that you all are moving away from KZread and have other irons in the fire you are tending. Good luck on those new endeavors and thank you for all the great content. One question concerning your project, I noticed you took all the paint and barrier coat off when replacing fittings...required for bedding compounds to mate to gelcoat and not paint. But then you put strainers over the through hull fittings leaving bare gelcoat exposed under the strainer...or so it would appear. Are you concerned at all with this little bit of gelcoat being exposed under the strainer w/out any barrier coat and/or ablative paint? I will be doing this same project this fall and am trying to learn all I can from those who have already done it. Again, thank you!

Ear protection, face mask ?

It’s not that they won’t work but expansion of plastic and it cracks you sink , can’t tighten like bronze

As a life long boat builder, what you are doing couldn't be further from correct. I would absolutely never replace bronze with plastic. Especially below the water line. First off what your doing will not even pass an insurance inspection. Anything below the water line MUST be a seacock, with a thru hull threaded into the second with 3 thru bolts through the hull. Then it should be tied into the bonding system of the boat. Plastic thru hulls should be illegal period. The only caulk you should be using is 5200 by 3M. Blue label takes a week to dry but the red label is ready to launch in a few hours. Plan on replacing the plastic crap in about 5 years if they are even still on the bottom. He'll a pressure washer will destroy them. Good luck.

Marlon is not an upgrade. And when it comes to thru-hulls, if you plan going away from the dock, us a proper flanged seacock, thru-bolted from the outside.

Replacing metal with plastic is not an upgrade. Below the waterline, bronze is the industry standard. Definitely someone working on a boat for first time. In a decade or so doing this work, will be qualified to make these videos properly.

Replacing metals with different composites it is exactly the practice in all the industry. From boats to space-ships….

The fiberglass backing board was not a good plan for the future. Getting a good bond to the hull, with gelcoat still in-place is difficult). Instead you could have grinded the gelcoat off the inside bottom of the hull and then tabbing in a couple of 3-4" strips of 1708 bi-axle tabbing strips using epoxy, would have be a better solution. Then once cured, drilling a center hole from outside of the thru-hull hole with a 1/4" drill thru the tabbed glass inside, then use a standard hole saw bit to bore the holes to exactly the size that you need for the new thru-hull fittings. And speaking of thru-hull fittings, that blue stuff that you called corrosion is the bronze doing it's job to protect the bronze metal fitting. You noticed the shiney surfaces once you removed them? Well you can bring the entire fitting back to it's original glory by bring it to a "brass" wire wheel (steel wire wheels are too harsh on bronze or brass) and removing the blue stuff and mild outside patina. Also use a round bottle or pipe brass wire brush on a drill to clean up the inside of the bronze/brass thru-hull fitting. THEN (additional tip) clean with acetone and paint them with "Speed Prop" and allow it to fully cure before re-installing them back in the boat. Personally, I don't trust plastic thru-hull fittings (they can break easier). An example of that, where you can go look up, is when a specific episode of Sailing Zingaro when he refitted his Oyster with plastic thru-hulls and one of them cracked and almost sunk his boat boat on it's maiden voyage at his first anchorage.

@TOMVUTHEPIMP

Zingaro is a clown who did not properly install the the thru-hulls. He just gooped everything with 5200 and hoped for the best with no load bearing collars. He did not even install the strainer the correct direction. Im shocked he did not hydrolock the engine. Also it was a speed sensor that popped out and flooded. Not a seacock issue.

I will never trust a plastic through hull fitting again. I hit a small log at slow speed and it snapped the plastic fitting off the outside of my hull and almost sank my boat. Bronze or stainless would have taken a peice of the log. No plastic below the waterline...ever
