All right guys, I know we have some time still but summer is going to be right around the corner. I haven't been paying as much attention to the threads regarding noise laws as I should. I am curious, what are all of you planning on doing with your boats that don't pass the newly enforced noise laws at the Havasu Marina. Are you all looking into getting some sort of muffler, or are you simply going to go launch somewhere else where they don't test? My boat didn't pass either, and I am not sure what to do. What are everyone's thoughts? I know its a bunch of horse shit, but the law is the law and it looks like its here to stay.

I would like to wait for the coming issue of Hot Boat that when they do some testing.
More than likely, I will wait for Rex to come out with their clamp on version so it will clear my swim step.

I just ordered some ggb inline hi flow exhaust. Hopefully they will work good enough. I know I wont pass right now but I got hassled by the man on my last trip to Havasu this past summer. I informed him that would be my last trip out without mufflers and he let me go. My question is can they kick you off the lake if your boat is to loud or do you just get a ticket?

Deano, not sure but I believe that each ticket carries a stiffer & stiffer fine, can get pretty ugly. Plus the pain of getting stopped each time I go out.
That's why I want to wait for a set up that will for sure get me under the limit.
I like the ggb's, just sure how much they quiet it down.

all the law enforcement agencies have been having meetings out here to decide what they are going to do once you get on the lake regarding the noise.
as far as we can tell no decision has been made yet.
with the boating season still months away I dont expect anything will be decided until after spring break time. Thats the way it happens in havasu

So far, there has been absolutely no difference in performance. I took sound levels at idle up to 2k and performance figures (rpm vs GPS) before the install. Just haven't been able to finish the job due to wind or weather when I have been out.
It is nice to be able to talk under way.
Here is the data from another thread:
Here is what we got on Saturday, tied to the Marina Courtesy Dock, stern facing the lake using the Radio Shack $50 meter. The levels up to 1500rpm were about 1 to 1.5db higher than the LHC Marina meter (when he was running it right )

Back when I had a Pachanga (I know Sea Ray :rolleyes: ) it had factory muffler boxes installed it and the exhaust exited through very cool holes at the waterline under the swim platform. I know this wouldn't work for the big blower motors but the 496's I think would do fine. The boat sounded really cool, kinda like a Vette.

No, if your exhaust exits under the waterline, you may not have a problem. If your exhaust exits above the waterline it is depenednt upon where it exists, how it exits (angled or straight out), is it a "euro-style"/integrted swimstep or just bolt on. All of these factors make a difference.
Word to the wise, the law is here to stay and if you're not legal, you might as well sack up and get some mufflers. Does it suck, yes, it most certainly does. But we were not organized enough and informed enough to try and fight it prior to becoming a law.
As I have said, we have the Rex Marine Silencers and have the 525 and prior to installing the silencers were way above the CA law. Now with the mufflers, we meet the law. Rex made a great product that looks good as well!

My '05 Carrera Part Effect with 496HO tested 86.4 (Havasu Marina's test). I put Rex's on and blew an 80 at the marina with the mufflers. Did not notice any performance change but for me the $$ spent is well worth piece-of-mind of not getting hassled out there.

Nope. In fact I boldly stated that TN didn't have any such law, then RD posted the TN law on the board. I have NEVER been, seen, heard of anybody being sited for this on the water. Cars are a different story. I have been stopped more in AL than TN. Those Nazi's down in Guntersville take their job very seriously!! We were even warned by other boaters down there not to step out of line. Sure enough we got stopped. :hammerhea

Not the case.
Below waterline "may or may not" pass J2005 idle case but "will not" pass the J1970 test. As soon as the boat moves forward (not even on plane yet) tips will be out of the water and wide open loud. Also without silencers of some type some LE may not even let you launch. LE's level and interpretation of enforcement remains to be seen and may vary from place to place as well.
The Livorsi product (actually made by Tom Beson at Northstar Marine, not Livorsi) is great for the J2005 test (very quiet because plunger is closed at idle) but pretty loud after throttling (plunger opens with exhaust flow). I'm confident they will not pass a J1970 test either beyond idle. Whether you get away running them will depend on the mood and testing procedure of LE IMO. They are also "very" expensive. They are an excellent built product unlike some others that I saw that were tested but IMO don't address open throttle running adequately in terms of noise supression required.
I was personally at the ***boat test for 2 full days last month at Elsinore and observed all the products and assisted with installing them on the test boats etc.

What is the worst case...I get stuck with it for another year :). I have no desire to be without a boat during spring/summer while a new one is being built though. I was hoping it would have sold by now but no such luck...Oh well....

Yes on the clamp-ons for 4 & 4.5. Can't give a date yet. We're building all the clamp parts because I didn't like the commercial HD band clamps that were available that many silencers are using. Too expensive to have them fall off when mounted on a short tip going down the lake (which happened to one product at the ***boat test btw). It is taking a little time to accomplish that but will be worth the effort. My guess right now is late Feb/early March on production clamp-on availability although I'm hoping it comes together sooner than that.
I have no specials planned, just trying to hold pricing where it presently is. I will post when I have more definate info.

Its news to me. I did see a letter that they were "considering" recommending the Northstar silencer but I never heard beyond that. It's pretty much irrelevent if the silencer won't pass a J1970 shoreline test at throttle though (at least in CA) which I'm pretty sure they won't by listening to them take off at Elsinore on a 525. The J1970 was not part of the ***boat muffler tests btw so no meter readings were taken.
Might be the double flapper issue Merc has. There were so many flapper failures in past years that Merc got nervous and started requiring mfgs to install 2 flaps.
We may actually make a model of silencer that will accept the ugly Salisbury type flapper in addition to our internal Superflapper. I just hate how they look. Makes em look like they belong on a tug. So far I've not had any manufacturers show interest in a two flap model.
There's no way in hell any water surge is gonna get by our silencer design (which in itself kills much of the backwash surge) with the Superflapper inside(which does not fail).
I think the present silencers look pretty cool. I hate to have to clamp an ugly #2 flapper over the end but we probably will offer it if it becomes an issue.

I have some questions, before I form an answer...
What exactly is NEW in the muffler/db law(s)?
There has always been db laws, are they tougher now?
Are mufflers needed no matter what db you're putting out?
Is this a federal law, or state (if state which states)?
Can someone who knows just lay it out please?
Thanks!!! In talking to several hot boating friends there seems to be vast differances in what people think is the law.
It is my believe that these new laws or law are jsut to give cops more reasons to have probable cause for stopping us and checking for alcohol, etc.. I also believe this is a "backdoor" speedlimit. With an unspoken intent to slow the boats down. But that's just my opinion...

Depends on what type (brand) of tips you have. I'd say at least about 2" to get a good bite with our clamp. Prolly could fudge it down to 1.5 possibly. The longer the better.

Rexone
01-08-2005, 09:23 PM
Jason the new CA law is not much different in terms of noise (it is tougher at idle) than the old J34. But is way easier for LE to enforce (test properly per spec). If you send my your email I will send you the J2005 and J1970 SAE test procedures which are both now part of CA law.
There are also a couple threads buried in HSW that contain the full text of the CA law. Just do a search on noise or silencers and you should find them. They are from last year.

Dean believe me with the clamps we're building they will not come off. That's a deficiency in some of the other silencers I've seen though.
No on the through bolt question. No way to put a nut on. Only way would be to weld a nut on the inside of your tip prior to silencer install. Again, unecessary IMO.

2 motors definately compounds the problem. I can tell you the more water the better as it does make a big difference. Of course water down the risers will kill the noise in short order too. :rollside:

I dunno if the louver core deals are gonna be quiet enough. I know a similar design bassett tested (dry) on OT exhaust didn't pass (on one engine).
The next problem I see for you adding clamp ons of any type is clearance on the steering rams and tie bar possibly (because those pipes are pretty long already).

2 motors definately compounds the problem. I can tell you the more water the better as it does make a big difference. Of course water down the risers will kill the noise in short order too. :rollside:
What dia are those tailpipes?
Didn't Boatcop or someone give us the math on twins? From what I remember, the db level of twins should be no worse than 3db more than the loudest engine.

Mike, after looking at a bunch of pipes, the Rex Silencers definitely look the nicest! I will be talking to you soon. Have been out of town for a while.

That sounds about right. Perceived noise doubles with every 3 numbers on the dBA scale. 3 is alot. And the higher on the scale you are it can be a whole lot.

Are those jacketed clear to the end (I'm assuming yes)
Nope. I'm not sure where the jacket stops- propably not long after the tip begins. :confused:

Yep...3 db means the sound doubled (it's a logarithmic scale).

Took delivery of the new ride and finally found a day with no rain to run it at Havasu just before New Years.
I went with the rex marine mufflers on a 496HO. They look nice too.
Havasu Marina wanted to test me, but I was allready half way up the ramp on my way out. (hello - here's your sign!) I was curious but did not want to put it back in the water for him.
How are they keeping track once they have tested you? Are we subject to random tests every time I launch there?

When I was tested, they wrote the results on my launch pass along with the AZ # (the one they give you when you pay for the day), and told me to keep it and show it each time I launched. Next time I launched there, I showed it at the pay station and they had me launch off to the side of the ramp furthest from the dock (boats needing testing had to launch dock side). They also had a list they could check your boat reg numbers on.

You are supporting the marina? :jawdrop:

They are using a tracking system based on your registration numbers.
