CMI ETOP tailpipe conections
 

How many flange types were made? & are the tailpipes compatible? If you have an older style Etop can the connection be fabbed up to work with the mercury style (500efi) tails??

is this an old design?? & would I be able to get new tails that terminate prior to the transom (connect to tips)

I know of 2 flange types.rope style gasket, flat type gasket.

Your headers are the old rope seals. I always liked these better than the new flex flair seal, the Mercury header flange is flat. You can easily modify your tails to work. Or, send them to CMI, and have them do it.

I like the Stellings better , just put a bead of high temp rtv and let it rip.

The merc flat style gaskets are 20.00 each dealer cost. thats stupid insaine, Trick sells them for 7 a pc. just think of the collector gasket of a header for a car. $2-3.00:angry-smiley-038::angry-smiley-038:

any idea on the cost? to convert them

The tail closest to the camera.What does it suit-Bravo?Looks like mine.Why would you not use this setup,noise?

yes they are bravo set-up's through transom tails, I am concerned about noise but not so much as not wanting to hog out the transom holes to 4.5 (although it is an option)

another angle
