I watch a LOT of boat videos, I plan on running away to sea myself in the next few years. Your videos are hands down the most informative, useful and meaningful videos I watch. They make me feel like this is doable and I say that as a professional educator. Thank you.
Great, timely tip on the FasSeal ATS thread sealant. Will use this next week, for my new hydraulic steering line fittings, as its compatible w/ the fluid!! Thank you!!
Update: I just checked my through hull path to the Little Giant Magnetic pump for my Heat/AC systems. I first removed the hose at the top of my through hull and attached 4' of the same 3/4" hose. (I kept the top of this hose straight up by tying some cord to it up to a hatch.) I opened the sea cock and blew through the hose. Easy. I also poured water down the hose. If the through hull was blocked this water would quickly fill up the hose. Not blocked the water level in the hose goes right back to sea level. I also ran a boroscope down the hose and through the sea cock. The through hull is a scoop type with a grating, so all I could see was bronze at the bottom. No barnacles or grass. Boroscopes are now inexpensive and work really well. Good tool. I then checked the strainer basket. Clear. I took off the cover to the impeller and found some friction melting from running it dry... but I don't know. I then disconnected the supply hose at the pump and attached the hose. I think this fitting was pipe thread, on my hose I attached a hose fitting. (These don't fit, but they fit good enough that at the very low pressure no water leaked out.) What I would do in the future is 1. Check the strainer, 2. disconnect at the pump and attach a hose and blow. Then I'd try to fill up the hose by pouring in water. It the water doesn't fill up the hose then it's clear all the way to the fitting on the bottom of the boat. If you have a straight open hole through hull fitting, then anything you can fit down through the hose can push a blockage out. I bought and used a four foot hose. On my boat sea level is about a foot above the sea cock, so two feet would've been enough. You don't have to put anything big down the hose. For 3/4 hose and fittings... I think anything up to 3/8" would work, but so would something much smaller. You can turn the wire to scrape all sides of the entrance. Hope this helps. Blowing actually seemed to work to check if the water was moving freely.
I'm glad to see your sea strainers installed above the floor boards. Mine are below and I've been looking for a spot to move them where they can be viewed, monitored and cleaned more easily. As i've disassembled my boat l've discovered many system installs that I did not care for but, because it is a Nordhavn, I've thought twice before changing. However, After replacing nearly all the AC electrical system and much of the high amp DC system I'm starting to realize This is just another old boat but at least it is a solid well designed platform that will be worth the work it needs. Again, it is go great to have your shared experience to instill a be of confidence as I dig deeper.
Oh wow, you sacrificed your whole cockpit for a second generator? The cockpit is the most important part of my boat. Eat meals, relax with a drink, read, have friends etc.
The 46 has a small cockpit. We spend our time on the foredeck. We have a big sunshade that covers the whole front. Just perfect, and the breeze is better, in our opinion.

Totally agree. Love the super detailed videos
Wow, what a super nice compliment. Thank you.
Thank you as well.
I love the straightforward way you make your maintenance videos. Keep up the great work. Thank you for posting.
Thanks for watching! Glad you like them.
I’m learning more with every video I watch of yours. Thank you 🍻
I am so glad you find value watching the videos. That and your comments mean a lot to me.
Thanks for Another great video. You take the mystery out of boat maintenance.
Thank you for your kind words. I appreciate that I can help.
Recently moved from sail to power. I’ve found you videos very informative. Thank you.
Thank you for the feedback. I am glad they are informative.

If the fitting is NTP, yes. If it is a JIC or flair, it shouldn't get any thread sealant.

Thank you for your comments. I agree with your assessment.
Thanks for sharing your experience, super informative and helpful video!
Glad it was helpful!
Saved our bacon 🙏
I am so glad. What did you work on?
Would there be any advantage or disadvantage to replacing the elbow at the seacock to a straight connector? Thanks. Awaiting my N475-49. Tushar
Yes, absolutely, but I need more room for a straight fitting. Thanks for your idea.

Is there room for a 45 instead of a 90?
It would be tight, but maybe. I'll check.
