Re: Seafari 25 performance
If hi octane fuel makes that much difference, maybe AV gas isn't so expensive after all. I'll look for the Pep boys stuff. I've been using Valvtect Octane boost. MMT is the active ingredient, no alcohol, comes in quarts, the most price efficient thing I could find. Definitely worth it if it raises mileage like it seems to.
Blue Heron: 3000 rpm for best fuel economy? What tests were you looking at? What I've seen, boat tests of 350s, look more like 3300-3400. What's the difference?
