...on a couple of threads, Ron. Worth calling them to discuss, I have one on my 40.5, but had the straight 4000 on my Vision 32 which I owner-installed. The 4000 on my bost handled everything very well for the nine years I has it, even in some pretty big sloppy stuff. It did work hard on big following seas, but it never lost it. Good luck, RD
