Yamaha and Volvo Penta Regain Award Status - 02/20/2008
Most contests are tight; customers grumpy about EFI fuel consumption and transmissions
The following information comes verbatim from the J.D. Power press release:
Outboard DI two-stroke segment
Mercury leads in the outboard DI two-stroke segment for a third consecutive year, with slight improvements in engine quality since the 2007 study. Evinrude closely follows Mercury in the segment. Transmission issues and stalling are the most frequently reported problems within the outboard DI two-stroke segment. However, two owner-reported problems, major engine failure and engine runs rough, have the most negative impact on overall satisfaction. Only 4 percent of owners experience either of these two problems.
Outboard DI Two-Stroke Segment Average 889
Outboard EFI four-stroke segment
Among all outboard technologies, four-stroke EFI engines have a particularly low number of reported problems (56 PP100). Among those owners who experience problems, those involving engine transmission are the most frequently reported.
Outboard EFI Four-Stroke Segment Average 888
Sterndrive EFI segment
Volvo Penta ranks highest in the sterndrive EFI segment, performing particularly well in the engine’s ability to accelerate rapidly, fuel economy and lack of exhaust fumes. MerCruiser closely follows Volvo Penta, receiving particularly high ratings from owners for engine reliability.
More than 57 percent of EFI owners indicate that their new engine is problem-free, while only 9 percent of owners report having three problems or more. The two most frequently reported problems by EFI sterndrive owners are engine transmission feels/sounds rough when shifting and issues with the engine tilt/trim.

Sterndrive EFI Segment Average 853
Inboard EFI segment
For a third consecutive year, Pleasurecraft Engine Group (PCM) ranks highest in the inboard EFI four-stroke engine segment, performing particularly well in engine reliability. PCM is followed in the segment by Marine Power.
While inboard EFI engines have the highest quality (49 PP100) and satisfaction ratings of all four engine segments, fuel economy continues to be a major weakness for the engine type.
“Fuel economy is clearly the Achilles’ heel of inboard EFI engines when you compare segment scores to those of the other engine categories,” said Todd Markusic, senior director of the powersports practice at J.D. Power and Associates. “Despite this shortcoming, inboard EFI engines have remarkable quality and earn extremely high satisfaction scores. Those brands that can find a way to improve the fuel economy of their engines would clearly have a major competitive advantage.”
