can i run my pipes up hill when dry with my inner tubes (water)extending 1/2 past the tail..........

probably be okay, until a back wash comes over the back of the boat, and you know at SOME point this is going to happen, schite always does, and then you stand a good possability of injestion and hydrolocing a cylinder..........

I am not an expert, but that would freak me out...........

i am having on puck of a time getting them to hit my old holes so i rolled them up to see what it would look like..............if i run them out the old holes they will sit about a 3/4 of a inch in the water and backing up scares the pee out of me.....

It looks like your water discharge tubes are inside those tails, so I would say don't do it.

Are they wet?

no they are dry with the tubes on the inside of the pipe but the water discharge sticks past the end a half inch

I think that it's a bad idea. My main concern isn't with reversion, it's with water finding its way into the pipe whether the engine is running or not. Rain may be a problem. Water coming over the stern in the event of an engine shutdown while you're running will probably be a big problem. If you are going to have to patch the bravo holes anyway, route the pipes to a downhill location through the transom. Just my 2 cents,

Bad idea with that set up in my opinion.

Looks LOUD!!

If you put turn downs on it will work. Otherwise bad idea.
