I'm pretty surprised my Sylvan 2100 didn't come with a fuel/water separator. It's a 40 gallon in-floor tank and I'm a trolling fisherman so I run the 150 hp main a fraction of the time of the kicker motor. I can probably fish for 2 months without needing gas. Should I add one or is it less of a requirement than I think? The boat is on the trailer after every day, so it's not like it sits in the water all season. I'm thinking of adding one but the fact it's gone 15 years without one has me wondering if it's really that big a deal for a boat that lives on a trailer. Wondering what is the general consensus?
