The engine (in case my signature isn't visible) is a 2000 OX66 250HP. It's on a fiberglass boat that sits in the water for about 5 months on the coast of Maine. I have been using the Yamaha brand (aluminum) anode. I've had the boat for 4 years and every year there is an excessive amount of growth on the anode... mussels, weeds, and some weird cylindrical type things/creatures. There is a small amount of growth on the bracket, itself, but nothing out of the oridinary there - except that the only place there is growth on the bracket is also immediately around the anode. The anode, by far, is apparently a magnet for this growth.
I am positive that the anode and it's screws are making good contact with the bracket. No part of the mating surfaces are painted. The SS bonding wires are in good condition. There is no pitting or corrosion of any of the metal that is in the water.
Does anyone else (that moors a boat) see this type of thing? I'm contemplating trying a zinc anode next year.
