Eddie marine switchable exhaust for 496 h.o.
 

is the inside diameter of exhaust hose on the h.o. 4 or 4.5 inches ??

The diameter is 4 inches on the 496HO...

If your boat has thru the transom only exhaust now and you are going to add a switchable silent choice type system, make sure you have enough drop from the manifold risers before you try pushing the HO exhaust out the drive. Sometimes this conversion can get in trouble with water backing up into the motor if the original exhaust was set a little high. Get an expert to look at your setup if you are not sure, its cheaper than new motors!

thanks,, Sorry for the confusion,, I meant switchable mufflers..

Chris,

I'm installing a set of the Eddies on my 496 this weekend. Let me know if you want any details.

i have a set of eddies on my 496 mag HO's ... they work great... quiet quiet quiet...

Thanks for the replies guys... I think i'm going w/ the 4" Eddie switchabe mufflers, they look nice and the price is right,, half the price of Silent choice.. just wasnt sure about the air vs. electric actuation, I guess each has their pros and cons..

Chris,

Be aware that even with the 4" eddies you still have to enlarge your transom exhaust holes to 4 1/2". I'ts not too tough just a bit spooky.

Thanks,,, 4.5 is the diameter of the tip itself right ??, the sleeve where the exhaust hose attaches is 4" o.d for the 496 h.o. 4" hose I.D. correct ??

we are in the process of having sunsation build our boat, so they can just make them 4.5 to begin with,,,

Perfect.
