Hey everyone quick question, I have a 99 h2x with a 454 mag and a bravo 1 drive with corsa silent choice exhaust. While pulling the plug the other day I noticed I have no exhaust bellows so there is a gap when the drive is up although it looks like when drive is down the two rubber pieces would slide into each other is that normal or did I lose the exhaust bellow some how? I don't take on any water and after looking at a friends 2000 bravo one on a checkmate I se he has an accordion type bellow any info would be great thanks... Mike

Accordion style is the quieter, but more restrictive way. Yours is fine and is very common, particularly on performance engines. It will be a little louder and have less restriction not having to push all of the exhaust out the prop hub.

Corsa silent choice typically has an rpm activated switch that opens the exhaust at 3?00 rpm. If you have that it doesn't matter what bellows you have or don't have below 3000 it's most likely underwater
