200k subscribers. Congratulations Stu. Another great video. Renko’s looking great. Really looking forward to seeing her dropped in the water and steaming north. Thanks for a great start to the weekend.
I love these simple explanations breaking the barriers to understanding. Thanks for that! Can't wait to see the launch. Yep when yer come back swap the props, if for no reason to get rid of that welded nut, and maybe get a zinc on the shaft. Safe travels
Capt Doug's advice must've been of extraordinary value in the refit. Your so lucky to have a man of Capt Doug's experience to show you the ropes, showing you how it's done.
Excellent work mate, Lady Musgrave, I dived that at 17yrs old (now 64) hopefully it is still as magnificent as it was. Enjoy! Want to see some video from that! Russ
The race against time begins as Dangar Marine hits the water sooner than everyone expected. Stu leads the charge in a last minute propeller change out with new materials to work with and a deadline that won't move. Emotions soar as Stu longs for open water again but must leave good friends behind. Join in all the adventure as Dangar Marine travels the globe in a newly refurbished Renko that motors as well as she looks.
In 1974 I was on a 52 ft trawler in Bundy,, hit something and bent a blade tip it was a 4 ft , 4 blade prop behind a 250 hp Cummins, slipped at Kepples Slip and the prop went to Maryborough ,, came back as good as gold,,
Two bits of congrats, Stu... First, for reaching 200K subscribers! Well done you! It's a demonstration of quality workmanship and superb video. Second, for a fantastic refit, well documented in the inimitable Dangar Style, and a lovely output. She looks gorgeous, and a newly-painted boat always runs a little faster, cleaner, and smoother. Next time you're up in the Southeastern US, give us a hail, and we'll meet you offshore for a beer. Fair winds!!
Super. I had no idea what was involved when it comes to this stuff as I'm more than a thousand miles from any ocean, and all we have are dinky freshwater lakes.Thanks.
So, um, Uncle Cosmo also liked to wipe down with a rag after he polished the shaft. Well, I mean, there's no real way to stretch that out. That's what he said. Nevermind. My granddad was in the RAF back in the day, and one of the things he told me, and practiced his entire life, was, if you've got a spinny bit and you want it to spin well, you have to paint a spiral on it. Painting spirals on spinning things makes them spin even quickerer because they know which way to do it right from the start. His Hurricane had a spiral painted on the propellor nose bit, and that span even better. His Hillman Imp had spirals on the hubcaps and they spunned quicker too. Or at all, really, any suggestion of rotation off a Hillman's wheels is an improvement over stock, let's be honest. His food mixer was spirally, his record player all heliacal. He even had spiral bedsheets. Not certain why. So, anyhoo, if they sell that special paint in different colours, try getting two and spiral that splosh-go-shove up. It's like painting something red, it absolutely scientifisually is then provably quicker, especially combined with the universally understood stripe down the middle that lets the air know to go around that bit. I know a red Renko would maybe look a bit wierd, and I guess overall speed is less important than mileage, I'm just sayin', spirals on the prop, stripe down the middle, red paint scheme = maximum top speed. You'd be wanting some hydrofoils, too, at that point. Handy for those high speed trips between Montevideo and Denham when the bilges get a tad arctic, if you know what I mean. Denholm Elliot was named after Denhem, as most people know, on account of his mum and dad needing to remember where they parked the Amilcar when they were there in '21. This was prior to the invention of spelling, or at least, prior to the adoption of spelling in the Great Strayans, although many modern scholars suggest that this seminal linguistic event has yet to occur across the Big Sandy Blob. I, of course, dyzargry.
Of what is the prop made? Could that prop be X-Rayed to look for hidden cracks? Renco is now a beautiful vessel! Thank you Stu and to all who made her so. Godspeed to all who sail upon her. RL Buffalo, NY USA
Very pleasant just sitting here with my Boston lager watching you work, Stu. Seems a smaller diameter higher pitch screw would give you less power at slower speeds, but higher potential top speed. I would like to add that I know absolutely nothing about this. Looking forward to the wet.
The Propspeed Clearcoat on the prop has to be applied thickly enough to flow out and brush the drips as it levels out to give you maximum film thickness for better durability and protection.
G'day Stu she looks terrific you've done a really beautiful job, and I know the hard work that you put into it. Stay safe and it's good to see you again mate kind regards John
Good job in discussing the props, you might actually get some reduced fuel consumption and torque from the prop change when implemented. It sounds like it is basically a one to one prop ratio. On a large inboard ski boat we had a 13/13 and with the boat loaded with a heavy skier behind you could pop them right out of the water and be up to 40 mph in a short stretch planing.
@@kylestephenson3004 - It's an issue with the camera, synchronizing (or, not) to the monitor - It only happens, through the camera - not in real-world experience. (There's nothing to be "fixed"). The only thing I could demonstrably compare it too is, to blink your eyes at varying speeds, to a blinking light; sometimes you'll see the light on, sometimes, it will appear off - or, you may catch it, between cycles, as dim (you won't see a steady rate of light, flashing) - Both, the camera and, the monitor (display) are working in, fast _on-off_ cycles, that the human-eye generally, does-not perceive - if, the camera is _'shuttered-open'_ at the same time the display, is _'blanked-off',_ it will be dark - this happens anywhere around 30, 60, 90 or faster, cycles, per-second.
good stuff Stu..enjoy the launch and trip to the lady mussy..there is often small patchy reception on the western side of mussy just outside the green zone so you can check that out while catching a trout for dinner..
Took me a couple of minutes to realize your camera was moving independently of you in the beginning. Glad to have figured that out before Dame chimed in -- would have scared the bejeezus out of me. 😅👍
Your boat looks great!!! Been following for a while now . I love a good functional boat. My boat don't go fast. But it's a great all around weekender /fishing vessel / explorering boat .. it can tread low water, but it can take the waves of the bay or open water.
"Film from much further away." Now, why didn't I think of that? It will work for all sorts of jobs, I bet. BTW, what's the leather book on the console...ship's log?
Great to see Renko improving every day after all that love and attention. I think the final act of kindness would be to treat her to a Cummins power plant, just to add that blend of sophistication and refinement.........just a thought from a well meaning viewer.
Hi Stu, I see trawlers using prop nozzles for gaining thrust and fuel saving, maybe with a bit of research one could be a nice addition to Renko, Kerry, Iluka,NSW.
Well, it looks good from afar, but it's far from good? :P Thumbs up to Astral for the great customer service. I'm looking forward to seeing the results with the slightly bigger but harder prop.
Hahaha film from farther away,piss funny,the hits keep on coming,you’ve done a bloody mammoth effort Stu,cheers for the vids,the old girl will have a good life under your hand,big shout out to Adrian for the donk work,did he start his channel yet?safe sailing Stuart.from newie.
I have used Propspeed a few years ago, Two boats and myself in the yard went in on a kit as it is expensive. My boat is a converted fishing boat 46 foot our home so it can sit for 3 or four months inactive during our nasty Pacific winter. hull speed 7 knots cruise 9 knots full on but pushing lots of water and using 40% more fuel. Back to the Propspeed. I swing a 34" prop with a three to one gear box so with a 1500 RPM motor speed the prop is turning 500 RPM. A 6-71 GMC. The reason for all these back calculations is that I found with the propspeed the prop was not turning fast enough to get any barnacle growth relief. I live on the west coast of Canada in the Pacific. Some folks paint there props with bottom paint, which can cause problems with the copper content, For the past 6 years I have been using Zinc spray in a can. Not cheap at $45 a can and my prop takes one and bit cans., and the barneys fall right off with a few rotations of the prop. Under the right conditions the propspeed could work IE: a fast turning prop...just not for me with my slow old craft.
Rule of thumb displacement Hull diesel like your Detroit is a “square” wheel. Diameter and pitch the same. Variance would be a few inches more or less pitch. Taking two inches out makes a noticeable difference with more power reduces boat speed . Adding a couple inches gives more speed less power and in many cases prevents the engine from turning optimal RPM. Only way to know for sure is test on the boat. I like the engine to be able to obtain maximum rpm and cruise comfortable typical load with couple hundred RPM less. If you plan to pull a big load go for less pitch. Tugs often have half pitch compared to diameter. High speed plaining Hull could have diamater plus 25 %
Yah ever need to stir something in a small can - put an allen wrench in a drill , and away you go, I've also used a piece of coat hanger bent into a small loop
Previous owner might have had it tweaked already? Prop manufacturer probably can help with how well the prop would work for you too. Don't think you could get much larger without hitting the hull or getting too close for comfort.
Hey Stu.. We're at Lady Musgrave Island every day.. We do tours from 1770 and you've been a great inspiration. Let me know if there's anything you need out there. But I'm gonna drop in and see you if that's alright . See you soon.. Brett

Nice to know the theory behind prop labelling. Renko is looking a million dollars!
That freshly painted bow looks great through the window. Didn’t like the gray at first, but I’ve got to admit it’s growing on me. Safe travels!
Great show Stu, glad Renko is back in action again, hope you're enjoying all the hard work. Jeff in LA USA

Always a pleasure to ride along with you. See you when you get home.
😮Never seen or heard of rope cutters on the prop before. Very handy.
Thanx Stu ! Been watching from Massachusetts and learning a lot !
Refit WELL DONE !
The attention span bit was hilarious. "Two or three eternities."
You are da man Stu! Great video. Looking forward to the next as always.

Congratulations on reaching 200k subscribers, Stu. Well deserved and I am sure you will continue to grow. All the best from the UK.
The prop you found I would take to a prop shop to have inspected, a decent prop doesn't get thrown in the scrap pile.
Of what is the prop made?
Could that prop be X-Rayed to look for hidden cracks?
Renco is now a beautiful vessel! Thank you Stu and to all who made her so.
Godspeed to all who sail upon her.

@@rlewis1946 A prop doctor can check to see if its bent. A bent wheel can do a lot of damage to the prop shaft and cutlass bearing.

Prop pitch is usually associated with the engine cruising rpm recommended by the engine manufacturer.

That nut I definitely can fix !! Can I use old prop in my blender
The difference between a 21 x 18 and a 24 square wheel is huge.
