Here is what i know for a fact.
1. I have original bellow(2004) for 1" shaft and 2" stern tube, it does not have rubber insert. Meaning the mold
used to make the bellow was for a 2" stern tube.
2. Replacement kits are specified in Stern tube diameter ranges. When I purchased a kit(2015) for a stern tube with diameter range that covers my need(i.e. 2" tube), bellow had a rubber insert to accommodate a 2" stern tube diameter. Meaning the bellow was made from a mold
that accommodates larger diameter stern tube, and an insert was used to get to a 2" size.
I explained my situation in an email
to manufacturer and asked if they had identical bellow to the one i purchased in 2004. I got an email
reply from them:
Unfortunately that is the only bellow we make to accommodate a 2" stern
tube. It has 1 rubber bushing that reduces the 2 1/4" inside diameter down
to 2". Please let me know if you require any further assistance. Thank you.
This is probably not a big deal, but given the criticality of the part, and that me and my family
live aboard on a mooring/anchor, 6 months out of the year, I need to digest this change.
My initial reaction when i got the kit was not good. I was pretty ticked off. I'll have to hear some positive feedback regarding the replacement kit, read up on it a bit, and by launch time, I'll likely have the new below with the bushing installed. But i will formulate a plan B that does not involve a coast guard rescue
, in case of a failure.
So if anyone knows the year of their PSS model, and weather
there is a bushing or not, that would help build some confidence that this change has indeed received some decent real-life testing.
