That's not a good number for him, and possibly why you haven't gotten a response.
I've been using him since Don (Double D)first told me about him 5 years ago. I use him exclusively for the stuff I'm unable to do.
Although I do 90% of my stuff myself, I am not by any means a boat mechanic. But I have been working on cars for about 45 of my almost 62 years, and am a pretty decent wrench turner overall.
I'm pointing out my mechanical experience only to qualify my recommendation to some degree. Chuck is an absolutely fantastic mechanic. He's very honest, and a really great guy. Like most people who deal with him, he has become more of a friend than anything else.
If you are still interested in getting hold of him:
I don't want to post his cell in a public forum, but you can email me at aol. My email address there is the same as my user name here.
He and his son (another really great guy) are now running LaSala boatyard in Copiague. You can also get hold of them there.
