New EPA rules will affect boats and lawn mowers

Nicole Hutcheson / St. Petersburg Times

With the Environmental Protection Agency announcing stricter emissions rules for boat engines, lawn mowers and weed trimmers, some are grappling with just what the new rules will mean to them.
Lawn care companies are worried about what the changes will cost them, while eco-friendly residents are eagerly anticipating the stricter guidelines.
The EPA's goal is to reduce smog and other pollutants by requiring that boats and lawn equipment have special engines that decrease emissions.


Here's what you need to know: What will be affected by the new rules? Gas-powered personal watercraft and inboard and outboard engines purchased in 2010 must meet stricter emission guidelines. New lawn mowers and other lawn equipment using 25 horsepower or less purchased after 2011 will have to as well.
How will the machines achieve lower emissions? Manufacturers will begin using catalytic converters in many small watercraft and lawn and garden equipment. An insulated chamber converts hydrocarbons and carbon monoxide in exhaust to water vapor and carbon dioxide.
How will using these converters affect the price of these vessels and equipment? The EPA expects an overall savings to consumers since the new technology will require less fuel. But the savings aren't that big. For example, a lawn mower that meets the new rules is expected to cost about $15 less after fuel savings are taken into consideration.
Can you still use your old lawn mowers and boats after 2010? Yes. But many boats purchased after 2010 and lawn equipment purchased after 2011 will need to have the new technology, which many manufacturers are already implementing.
How much more energy-efficient will these new engines be? The EPA expects that when the new guidelines are fully implemented, the rule will result in a 600,000-ton reduction in hydrocarbons, 130,000 tons of nitrogen oxide and 1.5-million tons of carbon monoxide each year. The new standard is also supposed to save about 190-million gallons of gasoline a year.

Will you be able to sell a used oil burning eng after 2010? If you are a private party.

In the long run, it will be good for the enviornment, but, it will cost us up front. I would assume it will also cut into performance.

ETEC motors already meet those standards. BRP knew this was coming a long time ago and have worked hard to design engines that have low emissions. :)

Yep, got a "clean" engine pushing my Reata and I would say performance has actually been enhanced.

I'm not sure that "exceeds CARB 3 star emmissoins" (the 2008 standard) also meets these new, more stringent requirements, since they're talking about catalytic converters for outboards. I couldn't find any relevant information on BRP's site.

YOu are correct in assuming that just 3 star CARB (california Air Resources Board) 2008 standards are not whats now going into effect. Carbonmonoxide (CO) is the only emmision of the 3 (Hydrocarbons, Oxides of nitrogen and carbonmonoxide) that has not been regulated and has been reported but isn't included in the 3 star rating.

Measured in parts per million CO is the only deadly emission of the three and the reason that there are warning labels on all new boats sold in the US.
WHat is CO? basically its unburned fuel. How do the 4 stroke companies plan to reduce the emission? Take the exhaust and pass it through super hot element (catalyst) to burn it off. A very basic description but this is what is going to be needed on the 4 strokes to meet the new requirements as the emissions are off the scale.

Here are just a couple numbers to give you an idea of the emissions numbers we're talking about

Reference the industial OSHA CO limits of 1200 ppm

Verado 225 55,000 ppm
Yamaha 225 45,000 ppm

Not having complete understanding of the actual proposed limits I can't give you a realistic idea to what 2 strokes will need to do. What I can say is that direct injected 2 strokes are already roughly 1/75th -1/100th the CO level of 4 strokes since fuel is injected AFTER the intake and exhaust ports are closed. E-tec is @ 600ppm and I'm not sure what Opti is but is low.

How does it affect consumers?
Increase in cost?, yes. 4 strokes will cost more to cover the parts and development
Increase in weight?, probably.
More maintenance?, Yes the catalyst need to be replaceable as in cars and trucks.
Reduction in power?, probably. Since the catalyst will be placed in the exhaust chamber, less exhaust flow means (generally) reduction in power.
Increase in engine temps and possible durability questions? maybe. Increase in back pressure from less exhaust flow (catalyst obstruction) will create hotter engine temps and can affect longevity.

These are the facts, not my personal opinions on the matter. I just want everyone to get an idea of whats happening in the engine development world now. Meet the emissions or don't sell the products.

cleaner environment, advanced products, we the consumer will win!

Once again, sorry for being long winded!

Looks like the "wave of the future", had to have 4-strokes have alot of issues to overcome with these new standards. I guess the oil burning E-Tec's and Opti's will be the top motors that everyone will have to have.

The way things are right now, this is all pretty silly in the big picture.
As China and India play "catchup", they are going to put so much pollution into our atmosphere that these little feel good ditties won't mean doodly.

The way things are right now...we'll do our part...and we'll know we weren't the cause of the wreck...but there will still be a wreck.
