Re: Removal of 496HO restriction plates
 

Without knowing for sure, I'd hate to cast any opinions about the silent choice. If I were to guess though, I would imagine you should see the benefit with or without silent choice. However, with the silent choice engaged, I believe that would cause a little more back pressure, so you would need to check into whether or not if that might create a problem...

Anybody have a pic of that plate?

Is the Raylar kit not able to be used with silent-choice?

Re: Removal of 496HO restriction plates
 

I think that I may have introduced some confusion with my post about Merc not recommending use of the Resonators with Silent Choice.

This has nothing to do with the use of Silent Choice with (or without) Turbulators. Sorry for the confusion.

dave n,
do you run in salt water?mine did'nt look that rusted,
just wondering about the difference.

Re: Removal of 496HO restriction plates
 

so I've got mine out as I removed the risers to facilitate an exhaust tip change. I removed the silent thunder box and am installing the larger Corsa transom mount muffs that Troutly hooked me up with. With the diffuser cones removed from the end...the sound should be just right. You don't get hassled here unless your pretty obnoxious in terms of exhaust note, but I don't want totally open and niether do all my cruiser nieghbors in the boathouse. ;)

I call an hour south to the only place to take the risers for strip and polish (do alot of marine and custom car work)...

SIX week backlog with all his guys working 10 hour days! :(

Dammit!! polished risers and painted covers would dress the engine room up a bit. Guess it'll have to wait. :rolleyes:

leaving the turbolators out BTW.

Re: Removal of 496HO restriction plates
 

I painted my cowls red and it really adds a lot. Polished risers would look awesome to top it off.

Re: Removal of 496HO restriction plates
 

Mine weren't corroded at all, just black from the exhaust.

Re: Removal of 496HO restriction plates
 

The story on that turbulator is that it is from a salt water boat stored in the water. A 39' performance cruiser that had a PWC lift and 800 pound PWC on the back, submergeing the exhaust tips and bringing the riser height to just 11" above the waterline. It was ingesting a lot of salt water. Check out the manifold below.

Ouch, that hurts...

So has anyone done their personal testing on these yet in terms of before/after numbers?

BTW, what kind of shop should I look up in the local yellow pages to get my risers polished while I have them off?
