You could try insulating that bulkhead with zero-clearance insulation, e.g. 'http://www.tbmparts.com/parts_item.html?cid=11530'. This stuff is often used to insulate fireplaces that sit right against wood or other flammable materials, and it blocks the heat almost completely. It's not exactly cheap, but it is effective. > The > only vent from the engine is through the pedestal (center cockpit) and > I've installed a series of muffin fans to assist the natural flow of > air, which will help keep the engine room cooler, but I don't think > that'll be the end of it. As much as I like muffin fans, there are some applications that require a lot more than a muffin fan can provide. I used a 4" blower fan from West Marine for mine: http://tinyurl.com/dd5dye . That moves a reasonable amount of air for my 52hp Mitsubishi engine, and runs when the engine does. -- * Ben Okopnik * Editor-in-Chief, Linux Gazette * http://LinuxGazette.NET * _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
