    Anyone has experience with Deutz aircooled engines ? Deutz makes the D914 L5 industrial engine application and it is Tier III . I dont know if I can use it for marine application . Plain ventilation in engine room (6 ' long x 12 ' wide x 6' height)

    I used Deutz air cooled, but not that size, much smaller. Yep, just about any diesel can be marinized, though some parts will need fabrication, if unavailable as marine.

    Thanks Par. Aircooled Diesel engines don't need to be marinize . All the marine air-cooled engines offered by Deutz are the same as industrial . My question is if I use an industrial Tier III version engine in marine application will the EPA still consider the engine as Tier III.

    How is the noise factor ?

    As I understand the new Deutz 914 engine noise have been reduce from previous models . No idea what number .

    Are you building new boats that need to comply with EPA?

    yes, it is a new boat and engine needs to be Tier III. Not to many Tier III in the 90 HP range .Most of what I look are high speed , expensive and high consumption. Maybe because the common rail injection system.

    The common rail, electronically controlled engines are going to have as low consumption as it gets. They are state of the art. You are saying "boat" in the singular. Is this for a single boat?

    It's will be hot in the engineroom. Air cooled engines usually have short lives in enclosed spaces because not enough cooler air is available. Probably half life or less. As the oil heats, it looses some of its ability to lube. Cylinder parts will wear like you're running a turbo. Hotter incoming air = less power. Hot ambient air = less cooling of the cylinder. It's like having excessively high exhaust gas temperatures.

    Air cooled installation can be short lived, if not properly setup. They're not inherently doomed, though some concerns do need to be addressed, if you'd like a reasonable life span. More than anything they're loud, but this too can be addressed and many very good products and materials can address this issue as well.
