You definitely don't EVER want to do this......... Thru hull exhaust at or BELOW the waterline is a big nono......

I cut 8" holes in the bottom of mine on my 357 and then installed the screw in access plate. That way I could have it loud when I wanted or quiet it down a bit by installing the access plates. Also, I removed the damn inside and removed the rubber flappers. I think the rubber flappers are the most annoying thing about the silent thunder. I really like the resonating sound they make when you remove the damn and flappers. I agree with Baja, don't get a boat with exhaust below the water line, just not a good idea.

forgot about those, yes I did. That is one thing I actually liked about the silent thunder that I don't think too many buyers think about until you own one is that there are actually a lot of options to "tune" your exhaust noise to what you want and what you family may or may not want. It also really enhances the look of all their SR1 boats, no doubt!

All vertical dimensions are for standard height manifolds and taken on the outside of the transom with ruler flat against transom. CMI requires precise measurements ensure system fit. Plus or minus transom measurements indicate minimum and maximum dimensions in which tailpipe transom holes may be specified. Radius angles are an additional charge. See Measurement Guide for instructions to measure tailpipe installation.

I guess stingray, baja, cobalt and a handful of others that do through hulls below the platform and below the waterline are doing it wrong. Never mind the aftermarket and riggers.
Stingray 230sx and baja 240 both have the exhaust through hull below wTerline from the factory
