It appears that Pearson built the 28-1 with what is now a mismatch: a 1 ½” diameter smooth fiberglass stern tube and a 7/8” propeller
shaft. The standard stuffing box size tube for a 7/8” propeller
shaft now has an ID of 1 ¾”, not an ID of 1 ½”, which is now the standard size for a ¾” propeller
shaft. Photo link: SailNet Community - jameswilson29's Album: Winter repairs
: replace stuffing box hose - Picture
Here are my options, as I see it:
1. Buy stuffing box for ¾” shaft and re-bore to 7/8” size (problem: will probably never pack right and will weep excessively or overheat);
prefab fiberglass tube with 1 ¾” OD and 1 ½” ID to existing stern tube to increase diameter;
3. Lay additional fiberglass to existing stern tube to increase diameter;
4. Buy and install ¾” propeller
shaft and alter all lower end parts (too expensive); or
5. Clean and wrap existing stern tube with silicone tape to add ¼' to diameter and/or coat with 3M 5200 sealant before applying hose to tube for better seal (problem: not structurally sound and creates difficulty with next removal of tube?).
Any other ideas? What is the best way to rectify the mismatch?
