Stuffing box stern tube issues

[UNCIVILIZED]

Were it me, I'd want to build up the smaller diameter fitting to match that of the larger one. In this case via adding a bit of metal. Though you could get some G-10 tube, have it turned to size, & then bond it in place, after removing the old one.
Also, I'd pass on using any lubricant to assist in installing the hose. The concern being that it could help the hose to slip back of.

I alway had to in my differents sailboats, and quite happy with the concept.

The PSS is great, but it does not replace a cutless bearing they are two entirely different pieces of gear.

Chamfer the last quarter inch on the forward end of the fiberglass tube to a little less than 2 1/4" with a file, put a little dishwashing liquid on the inner circumference of the stuffing box hose, and drive it on with a 2x4 and a 2 lb hammer. You need to use a proper 5 ply stuffing box hose for this, not a piece of radiator hose...

My last boat had the same sort of situation, stern tube OD was smaller than the stuffing box. PO just squished the hose to fit, I ended up with the leaks. I redid it and made up the missing OD with a 4" length of bronze bushing the right ID/OD from mcmaster-carr, slid over the stern tube with some goop, 4200? Then new hose from buck algonquin.

I'm another vote for the dripless. Had one for 10 years on an Ericson 35 and other than "burping it" when dropping it into the drink, never had to do anything except vacuum the dust in the bilge. If worried just replace the accordion rubber every 15 yeas.

My problem exactly. No 2 1/4" wire reinforced hose seems to be available anywhere. Shields apparently stopped making it. West Marine guy thinks I can use 2 3/8" hose with a hose clamp with a machine screw type tightened and it will be strong enough to compress the hose enough to make the stuffing box water tight. Worth a try I guess.

I don't think you would want wire reinforced hose for this application anyway. I'm going to pick up a piece of both ID hoses and see what works out best. I suspect my OEM was exhaust hose anyway as the wall thickness is 1/4" which is less than true stuffing box hose. but it lasted nearly 40 years!!

An issue I have heard of is with regular hose, it has a slight bend radius to it as it was rolled up at one time, where proper stuffing box hose was made straight, cut and shipped as straight pieces. Don't know it if this is true or not, but sounds right.
