None of what I posted was intended as a flame. While I disagree with genreal applicability of the points that you make I am not questioning that what you discribe may be true for some of the boats out there and certainly may be true for the boats that you are familiar with. I must admit that most of my diesel experience has been with European engines (Buhk, and Volvos), I have also worked on Graymarines, AT4''s and Universal Blue Jackets, Perkins and Westebekes. I have never seen a nuetral lock out sensor on any of these engines. My limited time onboard IP''s never exposed me to their engine bays.
I apologize if my comments hit you as being a personal attack. It was in no way intended to be that. I solely wanted to point out that transmission coolers and neutral sensors are a rarity in small sailboats rather than the norm.
