Hey Bob, i know from a previous post that you ran a 510 for a while and you stated it burnt 85 GPH at WOT, but can you remember what she burnt at her slow cruise speed? (say 18-24 knot range), and what are those man engines really like , I hear mixed reviews, and that if they go bad, that they are incredibly expensive to rebuild , what are they susceptible to,?, known faults?
Cheers for reading this
Regards Todd
