You have flushed me out Howard!
I have had the problem for about two years and have learned to live with it.
When it first started I contacted Martin at Airmasters and he offered to
modify the prop if I sent it back to NZ. As this involved expensive postage
costs and some downtime I looked at the two mods that seem to apply- one
being a ring of sealant around the blade retaining clamps external to the
hub ( Howard has this on his prop), and the other being SB 11 which was to
stop water ingress but it must also stop grease egress. I tried the
external sealant mod and did not leave the sealant long enough before flying
and it flung it out. The SB involves drilling into the base plate of the
blade and filling the cavity with sealant. It seems fairly simple to do but
I have not got around to it. During the last maintenance I replaced the O
ring seals under the retaining ring but that made no difference.
As Martin assured me it was not an indication of impending blade or hub
failure and may be caused by too much grease in the hub I relaxed a bit. I
might try the external bade root sealant mod again to see if that works.
I have tried to attach a picture to explain.
Regards
Brian

I can't get out to the airfield until the weekend to photograph the silicone
I'm hoping that Brian will post soon, as it was he who explained the mod to
me (if I try, I'll probably mis-quote).
And just to be clear, I know my prop is full of grease as I only recently
did it's 1st 25 hour maintenance check. Perhaps flown only 6 hours since
repacking the hubs with grease.
