We noticed last year that our speed under power seemed to drop as the season progressed. We guessed that marine growth was hampering the opening of the blades, and sent an agile crew in a face mask down to clean it off with a putty knife. This year we painted it with antifouling (a multi-coat special primer operation, since standard anti-fouling will turn your bronze prop to swiss cheese if it''s just slapped on) and we''ve been more diligent about keeping it clean. We also had the prop re-tuned by the manufacturer. Lots of things could have caused your sudden problem. The strong current may have closed the blades when you slowed down and they could have gotten stuck closed, caught on a barnacle or other growth. We found that when the blades didn''t open properly, shifting into reverse and then quickly back into forward usually did the trick.
