Have Gills on mine... a friend has same engines/same boat. In his boat with Stainless marine exhaust it's quieter. Mine sound better & are louder ( if you care about sound ) both at idle & especially underway at cruise & full throttle.

Have had zero problems with my Gills. His stainless are newer than my Gills & several studs have broken off at/in the riser. He has had to replace several.

I know several other guys whom have years & years on Gills without any issues, but you have to be anal about flushing.....thats one of the major keys to longevity in the marine enviornment.

Don't know, i bought the boat already setup with the exhaust. The only thing that may be different is that coupler 4" hose between the end of the pipe and the start of the silent choice. Look at your stock one to see if its the same.

I'm sure if you tell SM exactly which silent Choice setup you have they will supply everything needed.

Too Pld,
So what the catalog say ? Do ytou sell them ? and so you also sell a good exhaust gaskets (4) for those CMI's?
thanks.

Dtile,

What is that picture, it is very disturbing.

Cheers,

I have one set of gil's for sale from my hp500 with quick& quit and tall risers

I replaced a set of Gils with Imcos. Both came in and out really easy. I replaced the Gils because they failed. Given time, the Imcos will fail too. I think it's a design thing. Try to find a riser that will allow you to drain it completely. Some (with the "bypass" hose) let stale, salt water sit between the manifold and the riser. Install any gaskets so the fluids can flow freely, as in the stock Merc. risers. I think CMI has addressed this issue.

I put revolution marine exhaust on my Fountain. Price was right. About
a thousand a side 1/2 the price of Gil. So far they work great ( 1 Season)
Kind of a Biotch to install, but a 32 Fountain is pretty tight in the engine bay.
Mine also has silent choice.

I have been running Stainless Marine for about 15 years now on my 30' Velocity with no troubles ! The manufacturer told me if they ever did leak it would be on the outside, not into a motor! Good Luck ! Ron, OPA P-4 33 STEELINTIME !

Running SM on mine with 0 problems. Frankly they are buttet proof. The single clamp from the manifold to the riser is great for removing...no battling 4 bolts. The only gaskets required are the manifold to heads. I commonly remove mive if I need to work on something low in the back (starter, bildge etc.)

What are the best sets of gaskets for the exhuast?
