Yanmar D Series Marine Diesel Engine
(36hp)
Diesel outboards that work!
Boat owners quickly relate to the strong advantages of diesels.
. lower chance of electrical trouble.
. much better fuel efficiency
. long, reliable work-filled life.
When all 3 are combined, the case for a diesel becomes overwhelming. But what about small boats? Virtually unobtainable? That was until Yanmar launched its D series diesel outboards, creating waves of excitement amongst user and the industry alike!
Now instead of fickle performance common to so many gasoline engines, the diesel outboard presents operational savings and long-term strengths that make pure sense to the commercial operator.
