How does all the plumbing work?
There is a fresh filler on the left side of the engine bay and a waste water filler on the right hand side.

There is also a ball valve that has a hose running up front somewhere and has the outlet about 6 feet forward of the rear of the boat on the right hand side, basically right under the waste water filler.

Is there some sort of trick here?

When I flush the head, I can't see where the discharge goes.

The engine bay ended up with what looked like pissy toilet water in it. I'm lost here. Any help is much appreciated.

Noone know ??? this is doing my head in (no pun intended)

In the floor in front of your battery switches (under back seat stb. side) there should be a electric turd pump to dump your waste when ball valve is open, I was assuning the waste tank is under driver side floor, I believe there is an access panel in cockpit floor under or behind drivers bolster for getting to waste tank.....Good luck!

Hey thanks for that. It was a mystery and the manual from Donzi is crap!

I'll be in Brisbane for a trade show next, just give me the keys and I'll spend some time with it

come down to Melbourne and we will take you for a run. My prop and shaft etc should turn up next week. a few days to assemble and we are back out there...

Dont think I'm not tempted! I fly out next tuesday, get into Brisbane on Thursday, and fly back the following Thursday. I have a friend who lives down on the waterfront in Melbourne, would be great to stay with he and his wife and then meet you on the dock. might have to be another trip. I would be more than happy to wrench on ZR too, let's get that baby runnin again.

OK. Boats back on the water. Freezing cold here but an amazing day out on the water.


Can't find how to empty the waste tank. Couldn't find the switch. Any ideas folks?
