In situ painting? Using POR-15?

[ernst]

File size makes a huge difference in aggregate server storage. I always try to keep my pictures sized at 640 px maximum dimension.

Is a Megabyte or two really a topic these times? I can buy a 3Terabyte harddrive for 50 bucks and change on Amazon, and that will hold 3 BILLION photos of 1MB each. And I suppose if you buy them by the truckload, as surely the server farms do, it will be fraction of that.

Let see, if I would upload 100 such pictures every minute, day and night, it will take 57 years until I fill ONE $50,- disk.

No, I don't feel that I am abusing the hospitality of the server by uploading images in full resolution

Actually, it can be. Just last week on another forum the admin received a notification from the hosting service that they were approaching the maximum storage on their plan saying the pictures were the biggest load. They had few choices:

• Delete pictures themselves. This would have to be done by each poster editing their own content.
• The hosting service would delete them as necessary, oldest first to remain in plan.
• Go to an offsite image hosting service.
• Pay for higher storage capacity.

This forum has been struggling for a few years for a number of reasons IMHO. It's membership is small because it's for a single model of boat and is barely funded by Class Association dues which also partially funds a quarterly magazine. Registered forum membership is around 1900, paid Association membership is around 250. They are at a crossroads, either reduce the storage or find a way to feed the beast.

While our precious resource here does not suffer such malaise, it is still an example of how little things can add up. The forum limits your picture size to 1280 px for a reason. My suggestion of limiting attachment sizes further was intended as a courtesy to our host. There is nothing in a 1280 px (one dimension) picture you can't see in a 640 px pic.

Yes, small things do add up, and I agree with you that it is unlikely that anybody will miss details in my pictures if they were displayed with slightly lower resolution.

But we are talking about things nearly immeasurable small. Storing a picture in max resolution takes less than a MB (with compression). The cost of disk storage to do that is on the order of one-thousands of a cent. Are we really concerned about that?

But if it helps, I will in the future reduce the size of my images.

Thanks.

ernst,
One thing you could try would be to reduce the size of the original image at the source..Any real camera and even smart phones should allow you do adjust the resolution the camera is capturing.

I use free paint.net for photo editing. I just did a quick google search, and it does not run on Linux, but there are lots of alternatives out there apparently.

At any rate, my 1920 x 1080 monitor is seeing the pics OK..they are probably a little big on a smartphone's browser.

As for the painting, the progress on curbing the corrosion looks good.

Is the engine FWC ? If, so, now that you have a uniform color and it is easier to notice these things, there may be a bit of antifreeze dripping from the tee fitting in the manifold, Post #12, pic#3.

Well, yes, I suppose I could adjust the size of the pictures when I take them. But I did not take these pics specifically to post them, it is more for myself to document things so I can go back later and see what I did. So I want the highest resolution possible, just in case I might need it (Google stores them for free anyway).

But you are right, there are tools in Linux to reduce the size and I will do that in the future when posting to this site.

As for your observation, YOU ARE RIGHT! I did not notice it, either in the picture nor on the motor but there is clearly a leak! It is worrying that it is there even though the motor has never been used after the painting, so it seems to seep out without any pressure. I wonder if it has to do with the pesky leak whose source I could never find (see this thread http://www.moyermarineforum.com/foru...ad.php?t=11118 )

Next time at the boat I will investigate and report what I find.

THANK YOU!

If you had not had the resolution of the pic high enough we might have missed that!

FWIW, especially on boat stuff, I am always taking huge pictures and letting google store them for me as well. I usually take a few minutes to resize them before posting anywhere else besides my own computer, sometimes just to reduce load time. I lived on slow DSL internet for a long time.

Yes, I was in the same situation, and I am glad the DSL times are over!

Well, I did some work on the boat yesterday and checked. Sure enough, there was unmistakably coolant under the elbow at the top of the manifold. I tried to find where it came from but could not find anything. The metal seems to be intact, I don't think there either of the two connections leaks, and the hose if fairly new.

I tightened the hose clamp a bit more (it was pretty tight already). Then I put a piece of white paper under the connection. Today it was dry.

So, I don't know what is happening. Have to keep an eye on it.

[ernst]

Many things have happened since that last post, not the least a pandemic... I haven't used the boat at all since that last post (in December last year) and I only today ran the motor for more than a few minutes.

Mainly good news. The POR-15 is holding up very nicely when the motor is at operating temps (approx 180F). Of course it should, according to specs, but it is good to see that it actually does.

As for the leak that eagle-eyed @SASTANLY noticed in one of the pictures, it is a bit of a mystery. My first thought was that it was a problem with the hose. Nope. The leak seems to be where the 1/2" elbow with the hose barb is screwed into the T that does into the manifold and also hoses the temperature sensor. When I noticed this, I thought perhaps I had not tightened the elbow enough. I took it apart today, cleaned the threads and applied new pipe dope. Don't think I could tighten it more than it was, there is only so much force I want to exert on these brass threads.

But I was pretty sure that tightening the elbow into the T should do the trick. What can go wrong with that? Well, it turns out there is STILL a small drop developing at the threads!

I am a bit at a loss what is happening. What can go wrong with brass threads, tightened with appropriate force and with enough pipe dope? This is not exactly a high pressure system. But leak it does! Anybody hear of such a thing?

In any case, I decided to give up for today since the motor was pretty hot, as was the weather. Next time I go to the boat (when the motor will be cool again) I plan to stop by at Home Depot and buy a new brass T and elbow and then replace the whole thing. I hope that cures it.

[ernst]

I forgot to add the pictures. To orient you, this is a V-drive motor and we are at the forward end of the motor. In the Topview picture, the blue arrow points towards the #4 spark plug. The black background is the POR on the exhaust manifold. In both pictures, you can see the 1/2" T to the left and the 1/2" elbow attached to it on the right, the latter has the black hose attached to it.

In both pictures, the red arrow points to the connection between T and elbow, where I observed the small drop. In the Sideview picture, you can see that the elbow is tilted ever-so-slightly downwards, towards the hose, so it is very unlikely that the coolant flowed from the hose to the place where I observed the drop (also when I feel close to the hose, there is no liquid). The green arrow points towards a small puddle of (green) coolant on top of the manifold.

I'll leave the pictures in large size in case anyone observes something strange, as happened the first time Stanley saw the puddle in the first place.

Thank you for any comments!

I've never had much luck with pipe dope. 3-4 turns of teflon tape should do the trick unless the fitting is cracked. I had one that leaked that way. A PO had let the drinhking water system freeze, and I had a persistent drip at one of the elbows that would not seal. Examining it under a magnifier showed that it had a crack across the threads.

I see, so these fittings do fail. It certainly never froze (there was only coolant in there) but perhaps something else happened. After all, this is the standard Made in China item from Home Depot.

I just bought a replacement for the T and elbow (another Made in China product from Home Depot ) and will swap them out next time at the boat.

I will report back, and thanks already!

No offense intended here...
The brass fittings from Home Depot could very well be your issue.

I see what you're sayin...

Will give it a try. I will very closely look at the fittings that are on the motor and for that I have to take them out. I figured that I might as well have a replacement set available once I have all that out. Maybe that is the problem but I hope that at least the new one is OK. I suppose one could be bad but what are the chances two are??

How about just oil...

Thank you for the post and very knowledgeable educational for me discussion

I have the same problem with my engine, but I noticed (what I am sure all of you noticed too) that parts covered by oil don't rust. The engine has two sides, like Moon, oily, no rust, waterry, lot of rust

So how about removing as much rust as possible and then paint the engine with oil? Again rust protection not looks.

In fact I would say that my "training" engine looks better than the one (working now after applying Aforians or( rather Afurrians, since you have to have a lot of furry to tackle those lovely and loveable pieces of old junk) wisdom and assistance . Thank you for that. Link to youtube here. https://youtu.be/S3Hbva1fbcI

As always thank you for your help. Be well
