Hunter 36 stuffing box

I was just contacted by a friend with a newer Hunter 36. He wants to change the packing in the stuffing box. It appears there is not enough room between the coupling and packing nut. Has anyone else had this issue and is there an easy solution ?
We have a PSS on our boat so I'm not familiar with this problem.

thanks, Bob

Marlow Hunter (MH) reeeeeaaaaallllly needs their a$$ kicked over this one, but good. I would suggest your friend contact MH and talk to "someone ?" as Eddie Breeden has retired and I have to wonder if anyone is capable of filling his shoes. Tell them to step up to the plate and fix this one, in warranty or out. Completely unacceptable.

So much for the bit(hing, only two possible solutions here:

1. Move the engine forward which should be fun even if possible. Maybe permanently reposition or ............ move it each time he repacks. The latter would be a Stephen King grade nightmare.

2. Install a split coupling if there's enough room. I've never used one and don't see how to check for angular alignment. Maybe someone with the experience of owning one can provide insight.

I'd mention looking into shortening the hose but that's really going out on a limb as it acts as the flexible coupling. Shortening it too much would really set things bouncing.

This gives an idea of the distance required for a "comfortable" repacking job. I usually have it pushed far forward to get in with a dental pick for pulling out the old packing.

Maybe Hunter used too long a hose length on your friends boat??? Ralphs hose in his picture is more than enough for flex. Shortening the hose is a possibility

That's what I thought too. Should be easy using a sharp box cutter or knife.

my 2007 way plenty room for myPSS
what year is his
nick
thanks Nick, can you post a picture of what yours looks like so we can compare the two. I think the guys are correct, the rubber hose is too long. I have a pss on my H356 and have lots of room too. Picture of mine here, Bob

Taking one last look at this "dog screwing a football in a hat box" problem :cussing:, the most practical move might be to pull the shaft back and then remove the shaft coupling. This would require shortening a few socket wrenches (to fit between the two flanges) to force the shaft back from the coupling. Push the shaft forward. There would then be enough room to remove and repack the gland. Reverse the process and it's complete.

Still have to wonder if there's enough room in the hose to shorten it and still get to the bottom of the gland and remove the bottom ring of packing.

Any way you look at it, the work would be done on the hard. Probably as good a time as any to cut the hose and see if a shorter length will solve the problem. If not pull the shaft back and pack.

Please offer your friend our condolences.

after looking at the pic of the problem....two things come to mind here first ...i am not sure this is the correct hose for a stuffing box.....if you look at the hose clamp second from the left it seems to be compressed a lot more than the other three ..a stuffing box hose is much thicker than a regular hose and is a lot harder to compress the hose with that type of clamp....second thing it looks like way to much real estate between the spud and hull fitting .....i am thinking that the hose needs to be replaced with the correct one and also shorter...a 1/2 inch gap between the spud end and the shaft tube should be enough to let it flex as needed

1. Yup, only Bob can find out.

2. Great idea, most likely THE answer, given your photo. It looks like the hose is pretty new, so that's most likely what happened. Dumb yard monkeys, unless he did it himself. :confused:

3. Yup, too. :)

Good luck.

But it does say ALGONQUIN on it, which could make it the right hose but perhaps the wrong diameter.

yes it does say that and yes it may be the wrong size for the application.....it just seems to me that the hose is clamped way to tight to be the correct one for this application

I just heard back from the owner. The engine only has 50 hrs on it so this is a factory installation. They will have cranes at the club next weekend to lift the boats in for the season. His plan is to now tighten it up with the packing he has, get launched, next fall after haul out install a PSS.
Thanks for all the useful suggestions, hopefully it will be good to go once re-tightened with the original packing.

With only 50 hours it probably doesn't need new packing, just tightening up. A PSS is a great upgrade in any event.
The picture does look like the packing gland is larger than the stern tube, hence the crushed hose. Doesn't look centered either, but that's not that unusual, it's why they use hose.

Thanks Woodster, you're right ................... I thought it was my eyes and didn't want to say anything.

on a second look, it appears that the hose isn't all the way back on the hull tube - the compressed hose under the second clamp is probably because there's nothing under the hose.

Good suggestions, he will loosen the two clamps on the tube and see if it will slide back.

Attached is a photo of my 2009 H36. Never had any issue with working on the stuffing box but it does appear that I have more space between the gland nut and the driveshaft fitting. Angles can be deceiving but for reference, my driveshaft fitting terminates in the middle of the bulkhead partitioning the engine bilge.


Always wanted to know why the forward end of the engine is
only about 1/2" from the companionway ladder. Now I know!
