Pulled my shaft on my 76 Tique to replace the cutlass bearing, repack the stuffing box and replace the hose from the shaft log to the stuffing box. My question is, the stuffing box and shaft log are different diameters (1 1/2" on the stuffing box and 1 3/4" on the shaft log.) The hose appears to be tapered. Is this a stock setup? Where do I obtain this tapered hose? The one I have now is pretty dry rotted and I really want to replace it while I have the shaft out. Can't seem to find one on Skidim. I'm considering replacing the whole setup with a PSS dripless seal, but they are a little steep for my budget right now. I'd rather just replace this hose at the moment. Any help would be greatly appreciated!

Cool, thanks Tim! Is this just 1 3/4" ID hose that I need to clamp down extra tight on the 1 1/2" OD packing nut? Or is the hose actually tapered from 1 3/4" ID to 1 1/2" ID? I can't tell if my old hose was just dried out to that shape or what, but it looks tapered. Was debating whether to clamp down 1 3/4" hose or try to stretch 1 1/2" hose, or see if I could find 1 5/8" hose somewhere...maybe I need to buy a new packing nut with 1 3/4" OD. Mine sure looks like original equipment, can't believe it would be the wrong size.

76,
Please post a picture. How are you measuring? Tape measure? Calipers? They both should be the same - no tapered hose. Something was changed! The dripless is not needed. |

Thanks, Pete. Sounds like someone may have changed out my packing nut at some point. Maybe I need to change it back to one with a 1 3/4" diameter hose fitting to match the shaft log? Definitely appears to be 1 1/2" right now, just measuring with a tape measure. There is a noticable taper to my current hose and just holding the nut up to the shaft log, it appears smaller. |

I've been finding it a PIA to find the right hose for my shaft log/stuffing box. I know what you want is soft rubber hose (non wire re enforced). I picked up some 1.5" wire re enforced and it doesn't fit.
All the catalogs I've looked through say that a 1" shaft should take a 1 3/4" hose. I have a piece of 1 3/4" PCM water circulating soft rubber hose and it is too big. My next step is to take the log to a marine supply store and try their 1.5" and 1.75" hose and go from there. As far as the diameter of the log or stuffing box, do you measure the lip or the narrower section? |

Mine were evenly sized, but gettng it over that ridge was hard. I had to beat the ever loving daylights out of it to get it on. I got the log end on 3/4 of the way and enough to double clamp it. The nut was easy. Doc told me to heat it up in super hot water after the fact, which makes a lot of sense. He also suggested smashing it a bunch to "loosen" it. Mine is fine, but it really took some cussing and a couple beers to get it on far enough.

76,
Who knows what a PO or even CC did? CC has been known to do some weird stuff!!! They shoud be the same size. Buck Algonquin does list a packing gland that is for a 1&3/4" hose. As far as using wired hose, I've always used it. It can be a real problem getting on but I feel it's worth it due to the torque moment the shaft transmit through the stuffing box. I've seen a couple boats where the hose has been twisted to the point of ripping - usually from the owner tightening the packing nut too much!!! |

wire re-enforced hose is a must.

76, I just checked mine on my 79 ski nautique and it is exactly the same as yours. 1 1/2 packing going to a 1 3/4 log. My hose also looks as if it is tapered but it is old also.
It doesn't have wire reinforcement but I want to replace with the right hose. |

I like the idea of the wire reinforced 1 3/4" hose. Interesting that there are other boats out there with the same setup as mine, it definitely looked like the original hose and gland on there. Wish I knew where to find another tapered hose. My original one looks pretty shot - non wire-reinforced. (Main reason I pulled the shaft was to replace this hose.) I may end up buying a 1 3/4 gland, thanks for that link, Pete. Depending on how pricey the new gland is, I'm still thinking about going for a PSS dripless seal instead. Anyone have any good/bad experiences with these?

I thought I would post a conclusion to this old zombie thread as I haven't been on the site in a while and had a PM regarding it. I ended up replacing the packing gland with the Buck Algonquin unit suggested by Pete, so I could use the 1 3/4" wire reinforced hose. I purchased the whole unit (gland and hose) from Defender, I think this is what I got back then: 1 3/4 Packing Gland Hope the info helps somebody out if anyone else is dealing with this issue. Happy Spring, everyone! - Tom

Defender? Holy crap I haven't heard that name in 30 years! I managed some E & B Marine/Bliss Marine stores in CT & NY in the 80's and used to go into the New Rochelle Defenders regularly to "secret shop" their prices against ours.

Just fyi for anyone considering dripless. I've done a lot of research. Have an old v-drive & literally can't see the nuts to adjust, just a very vague glimpse with a mirror. And the space is so tight I've had to cut 2 packing nut wrenches in half, so no leverage. Have heard questionable reviews on PSS, and am about to pull the trigger on a Tides Marine Dripless Setup If there is room for it. System of choice in the commercial market and 2500 hour guarantee, at which point this 40 year old boat (or I) will be long gone......

OLD THREAD REVIVAL:
Any one have success with finding a suitable packing nut hose for the different size log-to-gland? My ('81 SN) has such a setup, exactly as pictured in this thread. The hose is soft wall, and the pieces are definitely different diameter. I disagree with the "someone changed it" theory...too many examples, So there must have been (and might still be) a hose available... Maybe a tapered automotive radiator hose?? |

You might search Gate's website, they have off the shelf molded hoses.
