Hope you get a response from your post.
I am here in upstate NY with an even tougher noise laws.
Should be getting my boat tested this week. Friends of mine with the sherriffs department using their DB meter to give me a base line to work from. 1971 Hallett V-drive flatty with a 396 BBC, tunnell ram and O/T Bassett headers.
How did you "win" your case before? Very interested in that.
Thanks, Jim
