Da na na na na...
Got my stuffing box apart...
da na na na na...
brought it on home...
da na na na na...
got it all cleaned up...
da na na na na...
but now the hose is so tight...

Well it's, so tight baby, I can't get the fitting in...

So now I'm singin' ... singin' the stuffing box blues.

OK, ok, I'll stop. But, seriously, the ID for the Buck Algonquin hose is 1 3/4", and the OD for the fitting (the stuffing box body) is about 1 7/8". That extra 1/8" makes it REALLY tough to get it to fit. I left the heat gun on the boat, so that's not an option. Can I boil some water and let the hose soak in it? What other tips do you have for getting it to fit?

Any tips that would also translate well for when I'm installing this on the boat (which I presume has a similarly over-size fitting) are also appreciated.

Before anyone asks...yes, I have 4 of the hose clamps, not just the 2 in the picture.

James, as I look at having to replace more and more of the stuffing box, the PSS is becoming more cost-effective. I may have to bite the bullet and install one.

Thanks to everyone for weighing in. I thought maybe I was nuts, or not doing something right. As JimsCAL pointed out, the only hose sizes I saw were 1.75" and 2". The 2" is listed as being for a larger diameter prop shaft, so I decided to go with the 1.75". I didn't even realize that there WAS an intermediate size!

Main Sail, thanks for your feedback, especially about the band clamps.

What I'm now having trouble understanding is how the shaft log works. On my boat, there is a large metal plate in the area where the shaft passes through the hull. The shaft log (I hope I'm using the right term; it's the pipe/tube that the shaft actually passes through) appears to be integrated into this metal plate. Am I wrong? Does the shaft log somehow get fitted into the metal piece (e.g., is it threaded in)?

The picture is big, so I'm not going to embed it in the thread, but here's a picture of the shaft log area. It's tough to make everything out because of the corrosion:

If I go with a PSS, will I avoid having to replace the shaft log?

OK, a few more questions. In the picture in my original post, the stuffing box body has barbs. I agree with smurphny, the barbs are more rounded over than pointy. Assuming this was new, and the barbs were pointier, would you measure the diameter at the tip of the pointy part of the barb, or would you measure the diameter as the base of the barb? I was trying to see how big of a difference there was between the ID of the hose and the thing that I was trying to fit into the hose. When I got the 1 7/8", I was measuring right at the "mouth", and did not take the barb height into account.

When I look at the stuffing boxes sold by Hamilton Marine (e.g., Packing Box Body 1"" Plain bronze 1""), I see that they don't have barbs at all. So, is the rounded nature of my barbs a problem?

The reason I ask is that I know I can find 2" hose. With the barb height, I might be close to 2" (I'm at work and can't measure right now). If the stuffing box body really is 1 7/8", then I'm going to assume that the shaft log is also 1 7/8" (I'll measure to be sure before I buy anything). Given that I can't get the better quality hose in the size that I need, I am naturally a bit concerned about safety. If this was above the waterline, I wouldn't worry as much. But this is kind of an important part. In that case, I may go with the PSS. But, there again, I need to know the size of the shaft log and how to measure it properly, because (as is almost always the case when my luck is involved) PSS sells one that fits 1 3/4 to 1 7/8", and they sell another one that is for 2".

Thanks Denise! I didn't see your post until after I replied above. I think you are probably right about the shape of the shaft log. I think the wide base in the picture you posted is on the outside of my hull, and is bolted to the hull by the bolts you can see in this picture:

http://dragonwingsailboat.files.wordpress.com/2014/04/img_3667.jpg

In looking at my picture more closely, I see that the shaft log does not appear to have barbs. That should simplify the measuring!

is the lip or barb corroded? it might be bigger than new, so try removing as much scale and corrosion as possible and try...
I cleaned all of the corrosion off. I may give the warm water bath and soap idea a try because I really have nothing to lose except damaging the hose. Though, as a practical matter, this isn't going to help me when I get to the boat, because if the shaft log is the same diameter, making it fit is going to be REALLY tough.

Trident was very nice - they said they don't make a 1 7/8" hose in anything but 2-ply. I did find a company, NovaFlex, who makes a 4-ply marine wet exhaust hose. And they are in West Berlin, NJ (so, relatively close). Unfortunately they don't sell direct. They gave me the name of a reseller in NJ, and the reseller doesn't have the NovaFlex 260 in stock. He's going to see if he can get them to send him a sample that's big enough for my needs. I'm keeping my fingers crossed! Otherwise, it's looking like I'll either have to go with a 2-ply, or do the PSS.

I'd like to do a PSS, but we have some other major expenses coming up and I'd like to put off the cost of the PSS.

Jim, that's my current plan. I'm going to swing past the boat early Friday morning to take the measurement, then head to a local prop shop to get the shaft and coupling fit and faced. I'll also probably have the shaft trued while I'm there. I'll see what they have in the way of hose that might work. Then I'll head back and start the install.

I took the day off and visited Dragon Wing today. I cleaned the shaft log and used calipers to measure it. The OD is 2". I used the calipers to measure the stuffing box the yesterday morning (rather than just using the tape measure across the widest part of the mouth), too - it's 2", not 1 7/8". That made me feel better, because I couldn't get any 1 7/8" hose that was more than 2 ply. I called a local dealer of Buck Algonquin hose, and they ordered some 2" ID for me. They said that their orders typically arrive next day, but they are only open M-F, so I took off today to get the hose. I also took the prop shaft and coupling/flange to the prop shop.

Have I mentioned that I don't really have the best of luck?

The owner of the prop shop is the only one who can run the lathe that is used to true the shaft and to do the fitting and facing. He had a doctor's appointment this morning, and the staff said they weren't sure if he was coming back today. Normally, it's the kind of thing they can do same-day, while you wait. But not today.

Since I was there and was waiting for the stuffing box hose, I knocked out a few small projects at the boat. I called the vendor at 1:30 PM to see if the package arrived. They had trouble finding the box, but eventually they did. When they opened it, the hose clamps I ordered were in there, but not the hose.

At this rate, I could have dropped the prop shaft off tomorrow (Saturday) and I could have ordered the stupid hose online, thus avoiding wasting a vacation day. 'Twas not a good day.

Capta, thanks. I'm not sure that it makes me feel better, but it does put my problem into perspective. :) I hope you guys are enjoying your honeymoon! FWIW, I have some "RTV silicone gasket sealant" from an auto-parts store. That seems to work well for applications where typical silicone caulk isn't quite robust enough.

Minne, I did get my dodger and bimini installed today. I realized that I was missing the straps that keep the dodger up, so I had to improvise, but hey, they are both up. I managed to do mine in the daylight, before the storm came. Good luck with yours; hope you got everything right!

Hello, thanks for the suggestion. I re-measured with calipers, and it's 2". So, I'm good. I have the hose on order. I'll be assembling everything as soon as it arrives. Hopefully I'll have everything together soon. If I can get back to the boat.

We splashed Thursday, and took the boat today. Had a little trouble starting her (batteries were lower than I expected), but eventually she started. Everything ran great! The packing gland dripped like it was supposed to. Maybe a bit too much, but not incredibly so, and I'll deal with that. I reached in over the engine at one point and although the engine was still hot, the stuffing box wasn't. So, I take that as a good sign.

Thanks everyone for your help and encouragement!
