The topic is back.....last year, in an attempt to inhibit the growth
of mussels on the prop and prop shaft, I coated them with
lanolin.....was told or read this would help. When the boat was
hauled in October, the prop/shaft were completely encased in mussels,
again. The growth has a noticeable, negative effect on the
performance of the prop later in the season e.g. higher RPM's to
attain same cruising speed when motoring. After trying a few so
called 'remedies', I am now convinced the only effective way to keep
the prop free of marine growth (mussels on mine) is to dive a few
times a season and physically remove them. Maybe I need a few pounds
of lead, my safety harness on and tethered to the toerail and a few
feet of hose the top end tied to the pushpit and me breathing from the
bottom end.
However, before I comtemplated something like that, there is one more
'remedy' I have heard/read about......it involves coating the
prop/shaft with "galvanized zinc spray paint". I have never seen
this done and do not know what effect it might have on the bronze prop
(shouldn't be negative but I'm not sure). There is never any marine
growth on my sacrificial zinc(s).
Has anyone heard of this? Anyone with any experience with this paint
on props?

Bob,
The breathing tube won't do it. I tried that as a kid and you won't get
any air. You'll need an air supply - bottle or compressor and a
mouthpiece to control the pressure.
