my friend has a scarab 454's w/ 41/2 inch glenwood exhaust , right now it has no mufflers at all and is very loud.. his neighbors are ready to sink his boat if he doesn't do anything about it . what are his options for controlling this w/o a full time muffler system,, doesn't gaffrig make something and where can we get it,.. maybe used?

go to eddie marine or teague and look at the switchable exhaust tips .... the go on in place or your exhaust tips and are switchable from open to baffled by electric switches...

good luck

I 2-USED sets (4 mufflers), fresh water use 4.5" Gaffrig "Super-Flo" switchable mufflers for sale with the air compressor for $1500 616-291-7932

I would go with the Teagues. They are great for supressing sound and work real well. Plus they company knows what customer service is. They do cut the sound just a bit when they are open but closed it is like I have through hub.

The Teagues work great, plus they can be had for less than a grand.

The Teague ones are ST-450 They are electric and reliable. Call Dino at 661-295-7000

Eddie use to make them for Teague and has the same thing for $695. They also just updated the electronics so the solenoids won't burn out like Teague's (I had them upgrade my Teague's with the new stuff-got tired of smelling burnt solenoids).

Barcat, if your friend is in New York, NY state requirement is "90 decibels or less when subjected to a sound test at the dock, or 75 decibels or less when measured while operating at any distance from shore. It is illegal to install muffler cutouts or bypass on any boat." Basically, captains call, etc and varoius systems are illegal and can be ticketed, if officer is a pr_ck. He may wish to look at a shotgun silencer type product.

Kaama - Did you get my PM about those Gaffrig mufflers you have for sale?

You can mount the tips 1/2 way or all the way under the waterline...Idle, sounds like a Jacuzzi, on plane, sounds good. Not sure if you want to re mount tips though!! Corsa makes some silenced tips, I think 8db quieter than strait trough, 390 a pair though.
