Re: Dry Exhaust Vs. Wet
Fred, Are there any mufflers that will work with a dry setup?
Why don't they work? Do they burn up? I'm gonna have to think about getting something to quiet these engines down soon, and probably this spring.
Would like a switchable muffler, just to use idleing around the docks, and in and out of the harbors.

CMI has a new muffler for dry pipes that's in testing. It should be released in the spring.
The GGB's appear to be holding up well and those who've bought them give me good reports. I don't have any real decibel readings on them with dry pipes though.

Re: Dry Exhaust Vs. Wet
Thanks Fred, but are the GGB's switchable? I don't want a full time muffler, so far all the GGB's I've seen were full time.
Like I said, I won't be needing em till June, but if something like what I'm lookin for comes up, give me a shout, and I'll take em.

Man that video warmed my heart!
Thank God my boat is faster than him and he always is behind me!!!

When I pass you Gl remember, I'm passing you with that extended cover girl that your buddy Phill says, "knocks 2 to 3 MPH Off the top speed".

Re: Dry Exhaust Vs. Wet
The small "boat" clamp-on mufflers don't do much with dry pipes. I never got around to trying it while I had mine, but always thought an auto style race muffler should work. I have a set of augger inserts in the side pipes for my Corvette. I havn't run mine yet but others using similar ones and the sound level is low enough to drive on the street. With a trans setup the tailpipes should be long enough to accomodate them.

1. Dry style tailpipes extend all the way through the transom and do not use any type of rubber hose connection. The tailpipe/riser is all one piece and connects to the header or manifold. These pipes are usually constructed from stainless steel.
2. A dry system would use one of the "Clamp-On" style mufflers available. These mufflers are also constructed of stainless steel. None of these muffler systems use any components that could melt down from exhaust gas temperatures at the end of the tailpipe.
3. The tailpipe is constructed so that at the end the inner pipe is swedged (expanded) out to form a seal with the outer pipe closing the water jacket. This does not form a perfect seal and you will usually find a small spray of water passing through this joint. In very few cases some builders have elected to weld this joint which can cause a problem with cracking due to the expanision/contraction of the pipes. Note that the cooling water is discharged through a separate fitting normally located on the top or side of the pipe about 6 inches inside the transom and connected to an overboard discharge.
4. Most manufacturers recommend that when you add a muffler system to the dry tailpipes you simply drill a 3/16" piss hole at the top of the inner tailpipe just before where the swedge begins. This provides a small spray of water to keep the mufflers cool. It's not enough water to cause a reversion problem.
5. If the owner of the boat did not drill the piss hole and the end of the pipe was welded so that there was no water spraying on the muffler system, the only result would be that the stainless muffler would turn a bluish color from the heat, it would not and could not possibly melt down.
6. The water in a wet system with mufflers does contribute to the mufflers ability to reduce the noise level. When the same type of muffler is used with a dry system the decibel reduction will somewhat less.
So to sum this up, GGB is not your only choice. Any of the clamp-on mufflers on the market today will work in this type of application.
