Well maintained engine ran great at start of fishing trip. While at full throttle, noticed momentary (quarter second) drop in power. Power drop started occurring more often, and for longer duration rapidly. By day four, engine was no longer reliable to operate on plane. Only alcohol-free fuel was used. As the power dropped, but was not lost entirely, I always guessed that one of three cylinders had stopped functioning.
New spark plugs were installed at start of season. Carbs were rebuilt in 2009. Fuel pump was rebuilt in 2008. Stator and coils were replaced in 2003.
