[C320-list] C320-list Digest, Vol 2203, Issue 1

Sat Nov 22 12:25:51 PST 2014

I opted for a Lasdrop Original bellow shaft seal on Hull 999.  I liked 
this bellows arrangement better and the rotating collar retention does 
not rely on set screws and therefore does not mar the SS shaft.  I 
thought it was a better overall design.  I also put a retention collar 
in front of the seal collar as a belt & suspenders.  Since it is a low 
speed application there is only a vent tube required that runs above the 
water line to avoid any trapped air pocket.   Really happy with it and 
the bilge is dry.

> I agree with Allan on the pss shaft. I replaced my original because the company recommended a change every so many years.? The original bellows looked fine when I removed it.? As far as the mechanics suggestion that a bronze shaft be used, I can only think that that was because bronze is softer than stainless and the set screws might hold better.? A poor suggestion since I replaced my original bronze shaft with stainless after getting a line caught around it and bending it. ?

I put a zinc on the shaft in front of the pss in case the screws loosened and the rotor should slid forward.? I actually ordered the old bellows at replacement since it just needs to be burped when the boat is launched.? I don't like having to put a hose above the water line as on the newer ones..? All that being said each of us have our own preference for our peace of mind.
