Stuffing/Packing Box Hose
I am going through the centerboard system on my 1968 Morgan 34. My immediate query involves the sizing and installation of the stuffing or packing box hose, which I am replacing.
The tube (think stern tube) exiting the centerboard well is 1-5/8" OD. The hose end of the packing box has a raised lip of 1-13/16" OD and about 5/16" in width, then narrows to an OD of 1-11/16".
From my internet research, I've settled on using Buck Algonquin Packing (5 ply) Hose. The nearest fits are 1-1/2" and 1-3/4" ODs. Will either of those work? Can I stretch (and if so, how) the 1-1/2" hose to fit; or, can I get enough clamping pressure on the 1-3/4 hose for a waterproof seal?
Also, I'd like opinions, experiences with using either a good quality t-bolt clamp or good quality standard non-perforated hose clamp (for example, AWAB). I only have 1" of tube showing from the centerboard well and am not certain whether I'll be able to get two regular 1/2" width band clamps installed. Might I be better with one 3/4" width t-bolt clamp?
All ideas/thoughts will be appreciated.
