    Factory maint. manual - source?

    Hi all, I've got the nearly usless Seloc manuals for both of my mercury outboards, but I'd really like to get the factory manual that would actually be useful. I've been looking around for one, but to no avail. Any ideas? The primary motor I care about is a 15hp (1991) Mariner 15hp. Thanks!

    Thermostats

    How often do you guys replace your thermostat in a small hp (15) outboard? I've been doing it annually (operating in salt water), but it feels like a bit of overkill. Thoughts?
