Pre Labor Day Greetings! I'm hoping some one on the board has gone from 2 stroke to 4 stroke this year.
I have a 2 stroke 115hp evinrude, 97, and I'm thinking of upgrading (slightly) to a 2002 4 stroke Suzuki. I've let it come down to fuel economy, and I would like to hear from some one who still has a fresh memory of gas usage on their 2 stroke vs the savings with their 4 stroke.
Thanks in advance!

Had a Merc 90 two stroke on my first toon. New toon has a Yam 150 four stroke. Without a doubt, the Yam beats the Merc in fuel economy, noise reduction and fewer emmissions. Go with the four stroke.

Like Jim Dandy, I also have a Yamaha 150 four stroke on my toon. That said, the two stroke technology has come a long way since your old 2 stroke. You might be remiss in not at least taking a hard look at the newer two stroke technology. I have one on my bass boat and the mileage is not bad plus the power is awsome.

Is the Evinrude still in good shape? I have a vintage Ranger tri hull bass boat that is in need of a better engine than I now have. If the 'rude is in good shape I might be interested in taking it off your hands.

Don't get your hopes too high.....boats just don't get good gas mileage. If you have a vintage 2 stroke, new technology 2 strokes and 4 strokes will be quieter and have better fuel economy, but don't expect miracles. If you have a rude with ficht technology (developed in the mid 90's) it will take a very long time to make up any significant cost difference of an engine change; even a classic 2 stroke will not have enough difference to justify the cost of change unless you are on the water a whole bunch and get a great deal on that Suzuki. One big advantage of a 4 stroke over older 2 stroke motors is noise level. However, times are changing and I have a 2009 Evinrude 2 stroke (E-tech, which is the next generation from ficht)). Fuel economy and noise level is very similar to current 4 stroke models....down just slightly from 4 strokes, but the upside is more torque and less weight.

I enjoy reading forum (lake martin forum that is) and you guys are why. Heard just what I needed. Think I'll stay 2 stroke and treat myself to a refurbed cover. Per U E McGill, I'm not on the water enough to justify the $$. Give me a wave when you see the smoke and hear me coming.

Do you want us to give you a wave or a high 5?

Great information and discussion, but would be better if put on "Boat Maintenance" so the other lakes can participate.
Have a safe weekend,

The Yamaha 4 stroke 115 or 150 is the way to go. I run the 150 on a 22" pontoon and I have found that the best gas mileage is around 15 - 17 mph.

I run a 225 Yamaha 4-stroke on a 23 ft center console. If I run 4000 rpm I get 4 mpg. If I run 5000 rpm I get 2 mpg. I run 4000 rpm.
|
Most outboard motors get their best efficiency at around 3500 rpm +/- allowing for hull shape and design....above 4000 rpm , the efficiency curve gets real bad. My toon gets it's best efficiency at 28-30 mph and just over 3000 rpm.
