Might anyone know what this hose is on the bravi 3 setup? It's on a 2000 Mariah jubilee 24 ,ft deck boat?

Exhaust bellows

Thanks. That is what I assumed. Does it really matter much if they are cracked open? any harm caused by it?

Won't hurt a darn thing.
Play all summer and replace this fall when you do drive service.

Something to consider: if the exhaust bellow is that bad off the others may not be far behind. That's one heck of a way to end a weekend and/or boating season.

I wouldn't get too worried about the exhaust bellows. I know guys who remove them & run without them. Personally i would do what Larry suggested. When you winterize the boat this fall, that's a good time to replace the bellows. And while you have the drive off, check the drive bellows closely for cracks or splitting. At Moto says, that's a far more serious issue. And heck, while you have the drive off, if your trim/tilt gauge isn't working and the sensor needs replacing that's a great time to do that job too cuz the wiring has to be run thru the outdrive/bellows.
