Just taking a guess but maybe turn the port side black Y valve (next to the front bilge pump) and it looks like thatíll send it in the direction of the transom drain (center of the 3 on the starboard side)

Iíve opened everything. I think the boat has to be on plane to drain it.

Is the boat in the water? Because that in deck well is going to be below the waterline so no it will not drain if it is relying on gravity and it is below the waterline. You will have to have it out of the water or up on a plane.

Spray some water from the hose down the drain and see if it's clogged.

if in day stack, have the fork lift operator tilt the bow up and if the valves are properly opened it should drain-if on a trailer you should drive up a s;lope to get the bow up and it should drain

Thanks guy. We had it draining while running yesterday. I donít think itís ever had bait in it so I donít think itís clogged. But Iíll run a hose in the drain tomorrow.

Itís below the water line. You have to empty it while on plane and then either plug the drain in the well or have someone close the valve while planing to keep it empty.

Try running your macerator pump(s) with the Y valve opened for that well?

invincible customer service should be able to give you a manual for the boat that gives instructions on how the system works-the marina where I stack my boat is an invincible dealer and I have seen the manual-it is nothing fancy, but it has much information

There’s definitely a valve that needs to be turned. Same thing happened on my buddies boat. We thought something may have been stuck and tried the hose which didn’t work. Kept messing with the valves and then it finally started to drain. It was a slow drain though, so you may not notice it unless you’re watching the water level. His boat was out of the water up on the lift.

It has to be running on plane to drain it and then you have to close the seacock or else it will fill back up, A complete pain in the a$$. On my 36 I added an in line pump and it is perfect now - anything that's in there gets pumped out even when in the slip. On the 36, the forward fishbox is also plumbed to drain so adding a pump will help with that too.

The in deck livewell can drain 1 of 2 ways - via macerator pump or via seacock. The seacock way only works if the boat is out of the water. If left open while in the water, the livewell will fill up.

The way to drain the in deck livewell requires turning 2-3 Y valves and hoses depending on the draining method - macerator pump or seacock. If the Y valves are not in the same direction at the same time, it most likely will not work.

MACERATOR PUMP METHOD - The first hose to turn is the black triangle Y valve on the starboard side closest to the middle of the bilge and bilge pumps. The pipe going beneath the seachest is the pipe that flows to the in hull livewell. In the picture, the black triangle Y valve is turned the right way. The second knob to turn is the other black triangle Y valve on the starboard side closest to the fuel filters. Turn this Y valve so that the arrows flow from the in hull livewell. These two Y valve direction should line up. Now the water will flow from the in hull livewell and turn at the first black triangle Y valve and turn again at the second black triangle Y valve and lead to the macerator pump. Now turn on the macerator pump and the water should start to drain slowly.

Seacock Method - If the boat is out of the water, you can use this method to drain the in hull livewell quicker than the macerator pump. 1st step is to turn the black triangle y valve on the starboard side closest to the bilge pumps. You want to turn the y valve so that the arrows are in line with the pipes so the water will continue to drain straight to the seacock with the blue handle. Now you will need to turn the black triangle y valve closest to the filters so that it closes off the in hull livewell pipe (pictured in the correct position). Then turn the second starboard seacock to the open position and the water should begin to flow out of the boat (if the boat is dry) or into the boat if the boat is sitting. The correct seacock to turn is connected directly to the pipe underneath the seachest (second to the left as pictured).

BY THE WAY - the black triangle y valve closest to the filters controls you forward fish box drains and allows it to use the macerator pumps. As pictured, the water should drain from the forward fish boxes through the macerator pumps & out of the boat.

I apologize if my terminology is not 100% accurate, but I know how to turn the knobs to get it to drain and flow. It can be a bit confusing because a few different pipes end up crossing, but this is how it is designed to allow you to use you macerator pumps for multiple boxes.

Feel free to PM me and i can walk through it or provide more details.

Wow. That seems like such a overly complicated process to just drain a livewell. My two livewells are above deck. Can anyone tell me whats the advantage of having a in deck one?
