If the 60 plus year olds cannot lift a 40 lb 4 stroke engine, it's time they start using their bodies in ways so they can.

I lift my 57lb 5 hp 4 stroke all the time and put it on the rail where a dinghy engine would go. I'm leaning over the stern railing when I lift it and I passed the 60 mark a while back

You have to use your body like you did at 8-12 years old at least a couple times per week if you expect it to work when you are older.

Try getting at least up to 3/4 speed at the end of your 2-3 mile runs helps I think. Then do pullups and pushups along with stretching before you do your run

Today's women are a different breed than back in your day.

I see them on base each day cranking up their motorcycles with their long braids hanging out of their helmets for the ride home in crazy traffic here

OK if so then explain how they have so many gasoline powered vessels in the world.
The engines and fuel tanks are in enclosed spaces .

I'm a bit surprised they haven't actually outlawed the use of engines that don't meet emission standards.

Sigh. When EPA introduced the Tier regulations (which have been phased in over many years), extensive provisions were included giving engine and equipment manufacturers years to modify their equipment.

For every person inconvenienced by a heavier, more expensive and more complicated engine; many, many more are benefitted by cleaner air.

A Tier 4 diesel engine produces less than 3% of the NOx of a non-tier engine. The air in most US cities is remarkably cleaner than 30 years ago (water, too), in spite of increased population.

I agree that ethanol is stupid.

Ethanol in fuel is worse than stupid -- it's political corruption. A bribe to farm state politicians. It would be much cheaper and better if they'd just give them a check.

But the rest of the world is catching up, thank goodness. A large part of the air pollution in California has drifted there from Asia.

I know it's fun to rag on the US. Sorry to burst your bubble.

Sorry to burst yours. Russia does have decent emissions standards but nobody there follows them. Their emissions standards are a joke and are broken with impunity (or at worst, bribes).

some stats from Yale:

and the EPI:

As you mention my country too has a less than stellar record, particularly of recent, in this area too. We are not the holier that thou league leading standard.

Canada does just fine. It didn't have to adopt the US standards. And a country of 35 million (less than California) probably doesn't have the market to impose more stringent standards, except at astronomical cost (although California manages to). It's captive to what the US and Europe do.

The company I work for exports engines to Russia, and they have to be compliant to get in (Euro-3, I think, not my area).

If we're talking about cars and trucks, Russian emissions standards work just like they work in the rest of the civilized world. Leaded gasoline has been banned for I guess 15 years at least, and all cars now have catalytic converters. The standard today is Euro 5, and all diesel and gasoline sold in Russia also complies with Euro 5. Europe is already one step ahead -- Euro 6. But Euro 6 is identical to Euro 5 for gasoline engine; it only affects diesel.

If we're talking about factories -- that's outside of my expertise and experience.


I've been visiting Russia since 1980, and the difference in air quality is amazing. The air in Moscow today is definitely cleaner than it is in the U.S. city I grew up in. In 1980, the air was a kind of orange haze.

One reminder on the 3.5 Mercury and the 2.3 Honda would be the smaller carburetor jets. Folks seem to always be on here with problems going that small. You would just have to take the normal precautions plus maybe treat the fuel with stabilizer

Your fuel mileage though should be incredible I'm thinking with one that small also

Carburetor jets.
And many of these four strokes, while purusing the spec sheets, indicate that they are good to a max 10% ethanol. This may cause issues with the 15% ethanol regulations. Or it is just a casual guidance without requiring strict adherance. Surely the salesman knows.

These bikes are all 4 stroke and appear to be running quite well on 10%. I haven't seen the 15% ethanol fuel here yet.


But then again some one above pointed out that women cannot handle heavy 4 stroke engines.....

Yamaha Enduro 2 stroke 15 hp weighs 86 lbs? If so that's 5.73 lbs per HP
Suzuki DF20 weighs 99 lbs, that is 4.95 lbs per HP.
What, the four stroke has a superior HP to weight ratio? How is that possible?

The enduro is by all measure a heavy lump of reliable. Not in the slightest a technological advance. It can be rebuilt with a screwdriver on the beach though.

Nice, but four strokes don't need to be rebuilt anywhere near as soon as a two stroke, don't foul plugs, etc, etc

I find that hard to believe, having had great long lives from various two strokes with bugger all maintenance, and since the advent of CD ignition systems, zero plug fouling.

Could you provide some corroboration of the relative lifetime claim?
