Piggyback underseat ballast question. 2017 210

[Soul_surfer]

Anyone piggyback underseat port side fatsac on 2014-2018 210.
Just want to make sure the pump can handle it and if it work fine.

i just need to put a T on my right pump, pass the hose to my port underseat fatsac.

my question is more for the Vent. I pass my hose from my underseat bag with a non return valve.
But can I plug It in the vent that goes from pro ballast to the tank?
or I really need to put the T on the hose that goes from the tank to the external vent? because it’s a **** of a mess to work there, no space at all.

Thanks to hear your experiences.

You should definitely run the overflow up to the thru hull overflow vent and Y it in there, or add a new thru hull vent. Real question is why are you adding under seat ballast to the port only? seems like a better option would be lead/steel shot weights if your just looking to fine tune the wave.

Also in my world the Right pump is for the Starboard side are you planning on using that pump for the extra port sac?

On the 210 we have 3 pumps, when you open the engine compartment and look at the motor, each pump are on the same side of their hard tank center pump is for the belly, right pump for right side (port), left pump for left side (strb). But when you look at it from the wakeplate yeah port is on the left side haha

and yeah, this morning I decided to forget about the project the overflow is too difficult to reach nd I don’t want to drill a new overflow just for that.
im Gonna get some lead weight.
if I plug the vent on the other vent water and air can be stock if the hard tank fills first.. so it’s not a good idea after all.
thanks for the reply!
