Silent choice???
How often do you guys actually use your silent choice? I'm looking at a couple of 42 Lightnings to consider buying, one has silent choice and EFI's the other has superchargers no EFI and no silent choice. ( I have heard it doesn't work well with blowers anyway)
Also, on a side note of lesser importance vacuflush or portapotty? Thanks all! Shawn |
Got rid of mine causes to many issues with reversion. And here we dont have noise laws but you are not suppose to have anything that defeats a muffler. So in a way the silent choose would be illegal, and have to be used all the time. Not that I think they would ever inforce it. |
What phil said. Silent choice mixes the water too early and can revert especially on any performance motor like the 500s and 525s |
Had silent choice on previous 525 efi boat, never had an issue but rarely used it because I was worried about reversion on long idle times. Current boat has 600SCIs and silent choice was removed by previous owner due to reversion in starboard engine that has short tails, boat is a full stagger set-up. Personally I would remove it to get full exhaust flow and not worry about reversion. If you have local noise restrictions, remove the silent choice system it's most likely an illegal system anyways and will not get you out of a ticket, then look into a set of tailpipe inserts made for high hp applications like these from GGB Marine https://marineexhaust.ggb.ca/. You can also look into turn downs.

With the proper diverters silent choice does not increase the risk of reversion. I actually get some peace of mind knowing that while not running, any water that might get past the tip flapper will run down the Y pipe and cannot wash over the hump and into the engine. I only use mine at idle speeds.

Thank you!

vacuflush works and are rebuild-able (not fun but can be done cheaply) so no worries

merc would say different. Many manufacturers added it to the blue motors but it was not recommended by merc. Many people have had issues with it. |

But to each his own, not my worry. |
The way the Fountain integrated swim platforms are designed, it’s not overly loud in the boat. The sound is all directed away from the occupants. I guess it depends on what/who you are concerned for noise about. If you want to be kind to neighbors on a quiet cove, you might just look into turn downs. |
You must make diffrences between builders of the silent choise!
I buy CMI and Corsa for my 600 SCi and get very fast rid of the Corsa diverters after compare them! The cmi are much better build,have inside a tubulator to hold of water(reversion) and mix the water extrem rear! I would not use the Corsa diverters on a Blue engine! They are not good build and i belive when many guys get reversion with the corsa stuff! Michael |
I'm removing mine as we speak and have a question. 2005 35 with 525's and Hardin Hurricane Headers. Would this tailpipe be a direct fit? It says direct replacement for the mercury tailpipe for 525/bravo https://www.hardin-marine.com/p-7406...8m0025008.aspx |
