Yamaha Fourstroke or Evinrude Etec Twostroke outboard motor?
The main reason for this is that people always try to sell you what they have. Personally I think that both types of modern outboard engine technology have some merits.
The main differences between Yamaha Fourstroke outboard motor and a Evinrude Etec Twostroke outboard motor?
Four-stroke engines are generally:
More moving parts
Higher service cost
Modern two-stroke engines are generally:
As efficient if not more (e.g. Evinrude ETEC)
Quicker to get going
Less expensive to maintain
Here is a great video that I found on youtube showing some of the major benifits of a modern Evinrude Etec twostroke engine over a Yamaha fourstroke.
To be clear we are talking about the comparison of a Modern directly injected twostroke Etec outboard engine (not the same as the traditional inefficient, noisy engine) verses a modern Fourstroke like a Yamaha outboard motor.
