Really thorough and interesting explanation. I do hope you will stick with making videos. It may take a bit of time and effort but there's enormous potential for channels like this where interesting and knowledgable people take things apart, repair and fix them - and boats are intrinsically interesting for a lot of people too.

Great video, very informative, in my opinion, it informs at many levels, overview of understanding (for all of us), details of how it works, (all of us) details to cover the folks who have a greater understanding of engineering, but not this specific engineering solution for control of water ingress on a shaft. Also please make sure you keep up the warnings to us all, we need to know when we need to call in the experience folks, and the consequences we risk if we don't ask for help. Great presentation the information is so good. This type of video's primary function is to pass on information and experience, and secondly to some entertaining. I hope with your desire to make the video more enjoyable (entertaining) that you don't lose the primary purpose of imparting information. I hope that makes sense, Best Regards Colin. Brilliant and thank you for time and kindness to share this with us all. 👏👏👏👍👏🤝🤝

Hi Darren, great informative video, well done. When cutting the packing cord i have seen that a cut of 45deg is recommended rather than 90 deg which kind of makes sense to me but I guess there's always 2 points of view. I've also read it should drip 1-2 drops per minute when running. I prefer no water in my bilge (being used to offshore boats with dripless seals) My new to me, narrow boat is 5 years old and only just done 200 hours but the gland was leaking grease and water (and there was a general purpose grease tub in the bay). I've just replaced my packing, and all the grease. The old packing seemed ok when removed, heyho at least I know all is in order now.

I completely disagree that the gland should drip, a good shaft and seal will work and stop water. If there is excessive wear you will in most cases still get a reasonable seal. However I have no complaint with 45° cut but for what it might give mehh ok if you want to why not. Makes sense. The grease will help that seal anyway. The old system that uses grease can get messy but it worked well and is ideal for the canal as it offers a solid support for the shaft. I've seen deep water seal systems not support the shaft as it uses a softer cutlass bearing. However ob deep water they are great. Hope that helps

@@dhcrouchmarineltd3049 thanks, that's good to know the gland should not drip. Will take careful adjustment to seal completely but not be overnight in order to stay cool and avoid wear. I guess dripless are more suitable offshore where the water generally contains less silt and solid obstructions to foul the prop.

I think you're eventually going to have a very successful channel. Keep working on being strict with yourself about the structure of these videos. The bit about the plate you are putting in to support the stern tube was interesting but it broke up the flow of what is supposed to be a discussion of "fundamentals". Maybe you could have put that bit in at the end as an interesting bonus. Also, good to signpost what you are going to do right at the beginning. I don't think you said in the intro that you were going to show us how to renew the packing. That said your actual explanations are very clear and informative and impart a lot of your good judgement and experience (not just the textbook stuff).

The last propeller cost around the £600 cast to order and the propeller shaft was about £300 The stern gland and bearing an additional £300 These are rough estimations and will vary, especially in the UK as raw materials have gone through the roof.

All that said, here's a question: I have a NB that I purchased out of the water with stern gear but no engine. There is some wear on the propshaft where it goes through the gland. How do you judge when such wear is excessive? What problems will it cause? I'm assuming I'll need someone experienced to come and look at it for me, so I'm just asking out of interest.
@dhcrouchmarineltd3049

Once I have a stern gland in my hands again I will make a video on how to re-pack it and what would be an acceptable amount of wear, the common issues you'll get, the gland seal will not seal, this causes obvious problems with excessive water ingress and the bilge pump will go off all the time, that effects your leisure power systems. Worse still if not monitored can cause a craft to list and sink in extreme cases. Excessive wear in the bearing part will stress the output on the gearbox and that gets expensive.

It may be just a case of tightening the gland. Usually its a balance between stopping water coming in and allowing free movement of the shaft. The gland must not normally restrict the shaft spinning easily. But ultimately older shafts and seals can be a little messy.
