I used the ones with the nut in the middle but I just used the old hose clamps to hold them in.

It's a performance boat,not a farm truck.Don't be lazy,just pull the motor and yank the Y-pipe.You will be much happier with the look and the extra room if you gotta work around the lower portion of the engine.Whenever I do somthing half-assed it drives me nuts till I fix it propper.It will take you about 4 hours and a case of beer providing you have usage of a crane.

I got the rubber plumbing caps. I had them on there for two seasons with no problems. Just secure them with clamps like you use for the exhaust. I recently removed the y-pipe when we had the eninge out. It just frees up a little room.

Actually it will take about 10-12 hours because there are two of them. As service is needed later I would pull them, but right now looking for a solution to a temporary and problem.
Thanks, for the input. And you are right, its not a farm truck and those thing sticking up would drive me nuts until they were removed!
Revised estimate..... 2 1/2 days... That case of beer always somehow adds time to a project.

Re: Silent Choice Blockoff
 

I used rubber hose and clamps:eek: :crazy: :crazy:
but it worked and we never sank the boat,Darin

perfect.:D

Jeff////////////// The ACCLERATOR 27 PITCH IS ON THE WAY!!!!!!!!!

I was looking at the welds on the aluminum box,no we did not WELD that:rolleyes: DARIN

Just thinkin out loud but why not pull the ehhaust hose and plug from outside.

Blockoff
 

Don't have hoses on the outside... Not a bad idea though to block off the outside also. I would not trust that to be the only plug, not underwater anyway.

I'm going to block off my Silent-Choice also, but I'm a little confused.............

Are you guy's using a round rubber plug with a nut in the end that when tightened it expands?? If so, then how are you getting that to plug the Y-pipe? It's Oval not Round!!
Or are you using some other type of rubber end plug???
The only way I was thinking it would work is to use the exsisting rubber hose that goes to the Y-pipe and instead of it connecting to the Silent-Choice, connect a piece of PVC pipe, then use the round plug like you mentioned. I wouldn't think you could use the pipe plug inside the rubber hose, could you?????
