Preventing a log paddle wheel from fouling?

We fitted a non-return valve which lessens the hassle when taking the log out even when underway. I clean the paddle wheel, spray with Maclube or something similar. That helps but we usually try (and often fail) to remember to remove whenever in port. In practice, I forget more often than not. When I hear a bleat of "No speed", I swear, go down below, take it out, quickly remove the grunge, put it back in, with only a small amount of water in the bilge. As with props, I do not think there is any really effective preventative.

That sounds exactly like what happens on our boat!
 
Went out fir dinner this evening, nice sunset sail and barbeque. First evening sail this spring. My logs not working. All fouled up. No problem just clean it.
Bigger irritation went over some floating debris after dark. got some brush jammed in my rudder
Spent almost an hour trying to clear it.
I guess I can get the diver to clean the log while he’s down there.
 
Got it free today. pulling both sides of the branch with my sheet winches lines routed through genoa cars.
No diver. and I cleaned my log impeller, I had my keel dropped and rebedded last year and bottom anti fouled. my log impellor is anti fouled.
