I saw that a heater Y pipe helps to keep the heater temp up while idling. I have a factory installed heater but it cools off quickly while idling.
Where does the Y pipe get installed and what does it connect to?
Thanks!

I believe it's between the raw water intake and the impeller housing.
Couple pics in here. I never installed mine because it was too hard to get to at the time.

I found it easiest to remove the water pick up hose between the vdrive and the impeller and install the wye outside the boat then slide it back in. I got a lsv and it was tight to install, skinned the knuckles then decided to pull the hose.
I think I just figured out how it works.
Am I correct that the Y on the intake line acts as the suction to pull the heat through the heater core? The hot water is still coming from the block.
I was thinking backwards earlier and wondering how the cold sea water would hear anything.
Thanks for the insight.
