Ok..I know most of you have a gofast.. :)
But has anyone ever run thru hull's on a 4.3 V6 ?
Been looking on the net....Have not seen anything for the V6...does anyone even make thru hull's for V6's?....Would like to find Captains Call or something that would allow noise on demand :D

Not for sure, but I don't see any reason why you couldn't do through hull with "captians call" on a 4.3L. Adapters, elbows hose and the actual tips are all universal, or "custom", which ever you prefer. It might sound funny though. wink

Yea I think it might sound kinda funny LOL...but..
with 3 or 4 inch tubes it should have a nice funny sound... :D
But I guess that is something else I would like to know...has anyone had thru hulls on a 4.3V6
What did it sound like...(a hive of bee's)

I knew a guy that liked doing things that can not be done. Speciffically, he wanted to hop up a OMC 4 cylinder. No reason other than he bought a trailer, and had to take the boat with it. :-)
Anyway, he did all the internal goodies, ported the head, and put a small turbo on it. Eneded up getting 375hp on a dyno. Then he hooked up the exhaust with a thru hull, and it did sound odd... So, thinking outside the box, he added a glass pack to it. Damned if it didn't work. Lowered the pitch, and smoothed it out nice. Ran great too, for about three hours when the outdrive went poof! Boat sunk in about 25 seconds. Still, my friend said it was worth it. Had a grand total of $1200 in the boat, plus labor. Works out to $400 an hour. :-)

Well I'm hoping for a few more then 3hrs...LOL
I really dont see it increasing HP by much if any...
I just wanna do it..just because I like the sound...and I have not seen or heard any other V6's...with thru hull... :D
But I would like to add them before any other things like cam/intake/carb...
So that when I do add the other goodies..it will be able to breath...

I've seen this set up many times resently on a donzi sweet 16. Sounded great! And you really can build that motor rather well. What kind of boat is it? As far as parts try corsca.com or eddie marine for the do it your self approch.

I think they do make this stuff for the 4.3 V6, I would check Corsa, Gil or Eddie Marine. I'm sure they aren't cheap, but it it's available, someone there should know. I bet it would sound kinda funny.... : )

With the water coming out of it, no one will know the difference! I have seen lots of them and they sound fine.

Don't knock the small engines, they can get up and move too! When I was a kid a guy in our group had an 18' IMP with a Ford straight 4, same bore, stroke, and head as a BBF 460. It had thru hull exhaust with merc I/O and absolutely hauled ass. This was pre-GPS days but the speedo was clocking around 70. Not too bad???

I know this will be a dumb question
But if I do straight thru exhaust..will it hurt to have the tips(with flapers) underwater(the top of tips will just be covered..they wont be deep) at a idle?...they will come out of water when on plane.. if anyone has seen a 180celebrity when setting in the water..the transom is mostly under water...till the boat comes on plan..and only other option would be to run them out of the corners of the stern..

This can be helpfull in sound reduction at idel, but... You will need hig risers, a steep rake, and I would put on flaps. You do have a risk of big damage if water backs up.

it would be a real steep angle to the transom..
it would drop about 8 to 10 inches...would that be enough?
