Default Dumping of waste

Guys help me out here if you can, 3500 SCR when trying to dump the waste to sea (in the allowed area) do you have to be moving? Also is it only the 2 switches at the helm?, sorry only ever pumped out

Huddo007,
I am not an expert here but is your boat equiped with the system for overboard discharge. Maxum installed the switchs as stock but the rest of the system (pump, diverter valve) was an option. Also before pressing both switches simultaneously you must switch the diverter valve from the holding tank position to overboard. See link for what the valve should look like.

I don't think theboat needs to be under way when discharging but I would move right after, don't want to swim in your own poo

The reason you must hit the two switches simultaneously is in case you hit one by accident, you won't Dave Mathews your friends and boat neighbors in the water.

Huddo007,

No, you don't need to be moving, but that is kinda like 'growling' one out in the bathtub. I don't want to be sitting in it either. I have dumped rarely, and only legally. When I do, I drop down to around 4-6 kts. It discharges like a bilge pump or an AC unit.......only not clear. Plus at slow speeds I can have someone confirm when it stops discharging. I can't see the discharge through hull from the helm.

Thanks guys mine discharges under the boat so I can't see anything, underway I can't hear any change in the pump noise to let me know its finished the only way I can tell is by smell, again thhe problem with that is not knowing when empty and the other day I tried it stationary and could not see evidence of pumping at all so now I have to check the pumps duck bill valves as it is turning just not pumping - thanks guys

Make sure you are opening the thru hull valve.

If it's below the waterline then i would expect it have a seacock. Though many freshwater boats are required to put a shut off to prevent discharge as well. though that is a freshwater thing. Mine doesn't have one.
