I've been using a red lanolin based grease called 'Propshield' on the
propeller and it's better than nothing as it keeps the fouling from
sticking hard so it comes off with a pan scourer. The propeller
manufacturer recommended NOT to use paint as they reckoned it increased
the risk of electrolytic pitting.

I have about 3' of exposed stainless steel shaft with an outer cutlass
bearing carried in a skeg just before the bronze Maxprop propeller.
I renew the anode on the shaft annually as it ends up pretty pitted
although there is still a lot of zinc left after one season. Never a trace
of pitting on the propeller, though.


We used PropSpeed, very carefully applied, very successfully. Took nearly 2
years to wear off, and before then, any critters slid right off under power,
or were easily dislodged with a bump from a plastic brush handle...

How do your end zincs do on your MP? Mine eat away pretty quickly,
usually - and I also use two collar zincs in the shaft in front of the line
cutter and prop.

However, this last time, the collars were entirely gone, while the cone,
while very deteriorated and partly gone, this time, didn't separate at the
mounting bolts as it usually does.

MP problem has usually been that the mounting points give way before the
mass and it slings off, damaging the bolt still attached, if not changed
soon enough (ask me how I know...)
