Mufflers for 496 HO!Please Help!
Hello Everybody.
I am from Germany, so please excuse my worse english.
I am driving a Tullio Abbte with 2x 496 MAG HO.
This Boat is Running at the Bodensee, and there the rules say that the boat dont have to be louder than 75 DB.
I dont want to go down the XR with the Exhaust, because i dont want to lose so much power.
I need your help , because i search for mufflers they dont cost much power and make my boat quiet.
I hope you can help me.
Greetings from Germany

RadPad ,
Your English is OK and we understand your question.
It will be difficult to get "through transom" exhaust with the 496 HO to be at a level of 75 DB.
However, adding mufflers to the exhaust tips may get you close to your noise level regulation on the Bodensee.
I am working on a similar problem, and have gotten some help from Fred at Trick Marine.
www.trickmarine.net
I am going with the new E Series muffler from Livorsi. It features progressive detentuation of muffling and back pressure that might bring you close to compliance. He can explain it more fully.
Good luck,
David Schirmer

Re: Mufflers for 496 HO!Please Help!
I am closing in on the completion of a Raylar conversion of my 496 Mag HO.
I also added full hydraulic steering with the Bravo Shop extention box. That caused me to lose my Corsa Captain's Call switchable exhaust (thru hull or prop ).
So now I have just exhaust straight out the tips.
I am converting those tips to the Stainless Marine with internal flapper. They have a lifetime warranty.
Then after in -water performance testing and propping, the Livorsi E Series Mufflers will go on.
Will repeat performance tests. Then test with Decibel Meter.
I will post results.

senecadds,
This is an easy fix with the GGB Extreme series.
http://www.ggb.ca/
They work better than anything else on the market today. I have them in stock. Please call or email and I'll shoot you the OSO members price. As with all my other stock I'm not allowed to post my prices....
