As far as Mercury goes, 87 octane is recommended in all outboards except 275 and up Verado's then it's 92 octane. We are also recommending startron.
Honestly, when 75% of my work orders are for carb problems related to debris, the best defense I've found is "RUN YOUR ENGINE". I have a friend with a 2007 225 Verado with over 1200 hours and he's never had a fuel problem or any other that I'm aware of. If you're not running your engine at least 30 minutes every week, standby for fuel issues. IMHO If your not taking the boat out, hook up the hose, get a cup of coffee and let the thing run in the driveway. Trust me, the whole "Low Hours" thing is a downfall now.
