Hose size for Yanmar YSE 12 Water Pump

[eebygum]

Hi, I’ve left my boat now and forgot to measure the hose size for my water pump so I can order some better reinforced hose (there is good flow but the current hose is showing some compression under suction).

Does anybody know the hose size, is it 19mm ?

and any recommendation on best flexible reinforced hose for short 6” lengths ?

Thanks in advance

I know that the YSE8 is 1/2", (12mm). I doubt whether the 12 is different.
