Anyone ever disconnected their Silent Choice and left the "Y" pipes in? If so, how did you seal off the "Y" pipe where the diverters?

i would like to know that too...

i would actually like to trade my gills with silent choice for a header and pipe set up to eliminate all that stuff..

anyone intereseted?

Do you really have to seal off the Y-pipe?....

I bought some stainless floor plugs from the Home Depot.

HMMMM.... FLOOR PLUGS?? GOOD IDEA!!

Never thought of that, I used 4" PVC.

i did almost the same as jhnrckr,except i used the black rubber female block off plugs from the plumbing dept. dont forget to double up the hose clamps. mine have been on for about 100 hours with no problems.




jhnrckr- did you use the ones that have the one nut in the middle that expands the plug or are they hose clamp type also.

If I'm understanding this, you want to block off the y-pipe. Mercruiser makes a plate that bolts to the inside of the sterndrive. With that blocked off you can remove the y-pipe altogether.

If you can get to it without pulling the engine????

GlassDave: Thought about the rubber caps, but did not know if they would work.
MKAST: You have to pull the engines to remove the Y pipe.
Reckless288: Not unless you want to sink your boat when you are backing up.
