Hydrochloric acid works perfect, but it affects the mercerator electrical motor. We used to use hydrocloric acid, but after destroying two engins we don't put the acid in the toilet any moore. If it is the tank that has clogged, put the acid in the tank from deck. But you need to leave the acid there for maybe one hour. The tank is made of GRP, so the acid doesn't affect that. And when the clogg is gone, the acid will pour out, as long as you leave the valve open. Rince thoroughly with water.

Or use vinaigre through the toilet instead. It does the same work, but needs longer time. Use 2-3 liters or more, leave it over night and then try to empty your tank. Repeat until the tank is clear.
This way you get both the tank and the hoses clean in the same time.

When you have (or if) you remove the lid to the tank you can also use some long stick to get the opening wider. The evacuation hole is mor or less straight under the deck hole.
