I hear yah Don. When I was a first mate in the Virgin Islands, we sailed 50' Morgans with little volvo diesel engines. The smell of diesel in the bilge while keeled over and pounding waves made most people lose their lunch. I was relagated to chef status, because I could handle it most days(given enough salteen crackers!)
Every once in a while the bilge would appear not to be working, which meant a trip down the crawl space. God what a terrible job that was! I couldn't imagine doing it for a living. Much rather drive them, than work on them. All of my boats have outboards for that reason! (Mind you I could never afford a liveaboard with built ins!)
