Jabsco electric head, using fresh water from the tank. 2008 Hunter 36. Last year was our first year with the boat. Head worked great. This year, flush is less effective. Due to health issue the boat less seen little use this summer. Literally at times the contents just spins in the bottom of the bowl and splashes a bit. If we hit the "drain" button, it goes down, but the "flush" button is less affective and doesn't actually ever empty of bowl like it used to. Maybe something in the macerator? a partial clog at the base of the bowl? Vent line is clean.
flushing question

Sounds like someone--a guest?--may have flushed something they shouldn't have( wet wipe, condom?) that's clogged the macerator blades. Or...the boat is a 2008...when, if ever, was the last time anyone checked the condition of the discharge impeller? It may be spinning but too worn now to move anything through the toilet.
You said the vent LINE is clean...but is the vent thru-hull? It's one of the two most common places for vent blockage because it's actually designed to keep sea water out of fuel and water tanks, NOT to provide the necessary exchange of fresh air with gasses in the tank that's so necessary to prevent odor from occurring. Boat builders, who are the worst sanitation plumbers on the planet, use 'em on holding tanks too because it's cheaper than using the right kind of thru-hull for a holding tank vent thru-hull.
So I suggest that you clean it out before you do anything else...use a screwdriver blade, ice pick--whatever works. If it has a screen in it, knock it out...screens become clogged with dust, pollen, air pollution and corrosion and serve no useful purpose in holding tank vents.
The second most common location for a vent blockage is the other end of the vent line--that end of the hose and the vent fitting on the tank. Tank contents can spill into the vent when the tank is over-filled or simply due to heeling.
Does the vent line run straight to the thru-hull, or does it has bends or --worse yet--any 90s in it? That'll interfere with the toilet's ability to flush.
