Noisy at idle. Seriously. Nice ****er, though.
Please feel free to post a video of yours at idle.
Assuming that you actually have a Yamaha that is. :)
I don't own a video camera.
Give it up guys................

This whole thing of 'mine is bigger than yours' is getting old.
But...my motor is smaller than his...not bigger.
And it makes less noise...not more!
Prove it.

Speaking of proof, I just checked the Evinrude site and could not
find a link that took me to the dozens of motor and boat test reports
you can find on the Mercury and Yamaha sites. The Evinrude site has
lots of pop-ups and hyperbole, but not the kind of hard information
that helps a potential buyer evaluate performance and fuel economy.

Can you provide the link there I couldn't find...appreciate it...
Maybe you should try again. There's all kinds of comparison data.


Yeah? In a non-hyperbolic format? I don't mean the sort of
unsubstantiated claims about "service." I mean, charts that show a
particular boat, with all its measurements and weights, air temp of the
day, what gear is on the boat, how many crew, how much fuel, what prop,
and the readouts of RPM, speed, fuel burn through the operational range
of the engine.

I couldn't find that link on the Evinrude site. If you can, please let
me know what it is.

Yamaha and Mercury provide the data...on the Yamaha site, it looks like
this:

Where are the similar pages on the Evinrude site?

Evinrude has a very similar data sheet on their web site, they actually
compare the same data between them and Mercury and Yamaha, all of them
side by side. The one I saw was for the 225 hp, and is Bullitin # PE333

In spite of Evinrude's claims, no fuel system provides increased power
and better fuel consumption.... by definition. You increase power by
burning more fuel in the engine.... either by supercharging, larger
valves, tuned intake and/or headers, increased engine size, etc....
but you can't get something for nothing.

Efficiency is another matter.... if they have somehow increased the
efficiency of the engine, maybe, but I've seen no claims to this
effect, nor have I seen any science to suggest that such a dramatic
improvement has been accomplished. (Where are the copy cats?)

Part of the magic, suggested by Etec's own figures, is that they under
rate their engine's horsepower, while other manufacturers tend to
overrate horsepower. The net result is comparing apples and
oranges.... or put differently, marketing hype.

Another often overlooked item is that with a 4-stroke vs. a 2-stroke
you can reclaim a lot of space onboard the boat when you remove the
weight and clutter involved in the VRO tanks and oiling system. I'm
also not burning as much as $.58 per gallon of fuel in 2-cycle oil
(50:1) .

When I dropped the 2-stroke Yamahas in favor of the 4-stroke Suzukis,
the engines weighed less, I gained a lot of space in the transom
locker, I lost the combined weight of the oiling systems, got better
fuel economy, didn't have to buy any more 2-cycle oil (retail
$67.50/2.5 gal.), and got a quieter running engine.

As suspected, I lost some performance, but again, you can't get
something for nothing! Works for me!



I've seen some 'Zuke repowers lately, a lot more 'Zukes than I've ever
seen eTecs out on the water, and they seem very nice. A few of my Parker
brethern have repowered with Suzuki four strokes.

The 300 hp 'Zuke is being targeted by some owners of 25' Parkers as a
replacement for a single F225. It weighs a lot less, apparently, than
the new Yamaha F300/F350.

'Zuke still seems to have problems setting up a network of strong
dealers, though.
