Make more horsepower, and use significantly less gas. It’s a promise that defies logic and chemistry, yet it’s been made over and over again in every form of motorized transportation – including of course the snowmobile industry.
This ad for the 1975 Evinrude Skimmer 650 starts out talking about raw brawn of its alternative-firing twin – “50 horses of high-torque power” set in a lightweight chassis. Count me in. Yet, one paragraph later, the ad brags about a new accelerator pump carburetor that “delivers maximum ‘go’ while still giving you the best possible fuel savings: up to 58% better mileage than last year’s models.”
Knowing that you need a proper mixture of fuel and air to create horsepower, and knowing that this mixture is a fixed constant (it is science, afterall), we can think of only four possible reasons this could be happening:
1) Either the previous year’s model had to be inefficient as hell; or
2) That previous year’s model was running unbelievable rich; and thus also wasn’t making much power while it bogged along; or
3) That previous year’s model must have been spitting unburned fuel out somewhere; or
4) This new model had its own secret science going on, which hadn’t be tried before or duplicated since!
Truth be told, the new carburetor probably did allow the sled to be dialed in a bit better, and the fuel mileage claim likely wasn’t comparing wide-open throttle to wide-open throttle. But, nonetheless, we’re guessing the marketing guys took information from the engineers, placed the data on the stovetop for a little bit, cooked and seasoned the numbers to their liking and then – voilà – the end result is a big claim for a new product. Yeah, we’re sure that’s the only time that has ever happened, in this or any other market!!
Either way, the Skimmer was a rather memorable sled with a rather memorable name, and it gave buyers a choice of rear suspension style. Enjoy the ad, and check back every Tuesday for our Vintage Ad Tuesday post of the week. Here are links to last week’s post, the Brut, and the choice the previous week, the 1974 Boa-Ski.
