Just got off the phone with Yamaha, there best 2 stroke uses 10-15 % MORE fuel than the same horsepower 4 stroke, no matter what horese power it is, and POLLUTES more it still sends oil out the exhaust,that's why it always needs to be topped off, just not as much as the old 2 strokes, Also top end should be the same,just hole shot is a little slower. Also he said fuel and oil savings will justify the extra cost of the 4 stroke and resale down the road will be higher.
So what you're saying, or the Yamaha guy, is that in addition to being slow, Yamaha's also get worse fuel economy, and pollute more. Go figure.
Also, I have been in plenty of Yamah 4 stroke powered boats. Not one. I say again, Not one, has a comparable top end to a similar boat with a 2 stroke on it. Case in point. 05 620 Ranger with a 225 Yammy 4 stroke. Terrible hole shot, and a top end of 47-49. Same boat, pick your 225 HP 2 stroke. Opti, E-Tec, and yes, even the Yamaha HPDI, all are significantly faster, holeshot, midrange, and topend. 52-56 MPH.
Fuel savings? What fuel savings? It's a well known fact that the big 2 stroke DFI's get better fuel mileage than the 4-strokes. And not just at WOT. |
