Stuffing box shaft log hose connects the fiberglass shaft log to the bronze stuffing box.
• 4 high quality type 316 stainless steel hose clamps
• Installation instructions
We believe, based on occasional mention in Catalina's literature as well as reports from a few Catalina owners, that the 1-1/2" diameter shaft log
was used on a few early boats. These include the earliest Catalina 27's as well as Catalina 30's equipped with the Atomic 4 and Universal 5411 engines. There may be other instances where 1-1/2" was used as well.
The clamps we include with this kit are made entirely from type 316 stainless steel for exceptional corrosion resistance.
The design of these clamps is also superior. Normal clamps, which have slits in the strap, engage the rubber as soon as the clamp begins to tighten. The clamp won't slip around the hose which limits the tightness. Further tightening just damages the hose.
These clamps are made with the "gear" formed on the outside of the strap. This leaves a smooth surface on the inside of the clamp. The smooth surface allows the strap to slip around the hose during tightening, creating a tighter grip on the stuffing box and shaft log
. They are particularly well suited to stuffing box installation since due, to their location they are difficult to inspect regularly.
• Inside Diameter: 1-1/2"
• Wall thickness: ~ 3/8"
• Outside Diameter: ~ 2-1/4"
• Length: 4"
Unfortunately Catalina's records regarding the length of hose used in each boat are not complete. We believe that our 5" long hose will accommodate most Catalinas. If yours is shorter (many Catalina 30's use 3-1/2" long hose) it can be trimmed carefully with a hack saw. If you believe your hose may be longer than 4", please measure before ordering. If your hose is longer or has the smaller inside diameter, please give our tech support line
a call. We may be able to help.
