Silent choice Y pipe leaking water
 
as rpm goes up, i hav a small leak from the pivot pin in the Y pipe, so water leaks inside the bilge
and i tolerate no water in my bilge, like nothing.
Are these leak fixable? Or i need to buy new y pipes?

The rubber boots on mine have always covered those pins. Possible yours are too high? Those pins are near the top of the y pipe. The replacements don’t use the pins but have nubs that snap into those holes.

Times 2. I also had a leak on a new boat I purchased last year. Flapper was removed per service buliten and the rubber boot was to high and not covering pin.

I dont have any rubber at least not on the swivel pin
i have one on the actuator on each pipe, but none on the swivel pin
should i? Not even written what brand it is...

Call Corsa Marine, there are two o rings on the shaft that need replaced, most likely they will send them n/c

For future reference, that is your diverter valve not y-pipe.

Yep they leak there. See one to 5 every year leak. Sometimes after the heat builds up they stop leaking. Sometimes once again.

I have a Volvo Penta 8.1 OSi with silent choice and it is leaking from it which is filling my bilge with water.

See post #5 (unless you have a warranty) but that is more water than I would suspect from a leaking Diverter pin....
