The engine is a 3.0 OMC. The center section is a Wayne Taylor 16". The exaust usually exits turned down like the Mercs. He does have a plate to fit and lessen the noise.
Since I live on the left coast and I'm worried about the sound police we came up with this. I already had the SuperTrap on my other OMC center section. He made the adaptor to fit them togeather.
The center section has a curved plate to direct the majority of the exaust out thru the muffler.Gary

too cool
Thats a hot set up. Im up at the crack of dawn [some guys know her}and thats the only time we get flat water on lake michigan. we live on our boat in a huge marina.Its a ten min ride to the opening.There is nothing worse then a bunch of hung over boaters shooting flare guns at my head. So I wish to keep the peace.So my next question is do you have to do any adjustments to the motor with the muffler on. Is back pressure an issue.do you have a part # for that muffler? did you make the connection with alum or ss ? thanks guys.be nice to me im frail but my boat wants to kick some a##

Exhaust
I will take some pictures tomorrow of a trap door style exhaust plate that I built for my offshore mid. It works on two hinges on the bottom and uses a spring on the inside of the exhaust snout to keep the carbon fiber door closed at low speed and then allows the door to open gradually as the exhaust pressure builds. I think it's pretty trick.

Exhaust Idea
Here is a trap door that I made from a sheet of carbon fiber and then inserted a piece of flat rubber stock on top of the carbon to make a seal on the inside of the exhaust snout.
There are two brass hinges (home depot) that attach the trap door to the bottom of the exhaust housing and a one inch diameter spring that fits to the door and to a thru bolt mounted to the exhaust snout. The spring keeps enough tension on the door to keep it closed at slower speeds or untill the motor is reved a little. Springs can be changed to alter the point at which the door opens. This thing has been bullet proof for the last three years, just an idea which seems to work for me. Hope it might help.
Best wishes, Carter Powell

Exhaust
About 90 percent of the exhaust is going thru the prop when just idling around. If you go full throttle it will open up untill you are on plane then start closing back up untill you are really on the throttle. At wide open throttle it will be open about two inches. It is amazing how quiet it is when idling around. The snout is usually underwater when idling. I'm quite amazed how well this has worked out for the last three years.
