Snowmobile Weight Matters

We stormed into three snowmobile dealerships in the greater Minneapolis, Minnesota, metro area and weighed sleds on their showfloors. Every machine that was hoisted onto our scales was fully assembled and fluid levels were ready for the trail except for fuel and injection oil. Four-stroke engines were filled to factory levels.

We weigh the machines and report their weights without fuel and injection oil because capacities vary between make and model. Chaincase oil, engine coolant and shock and brake fluid capacities vary, too, but unlike gas and oil, those components must be filled to the manufacturer’s specification in order for the sled to go down a trail. Manufacturers deduct these fluid weights to arrive at their estimated dry weight spec, but the number in the brochure means little when a rider climbs aboard.

Most two-stroke-powered sleds are shipped from factories with just enough oil in the reservoir to prime the oil injection pump. Most of the tanks in the sleds we weighed contained less than a pint of oil. At just 1.784 pounds per quart, the effect on a sled’s weight is negligible and was not used to determine a corrected weight.

All fuel tanks were empty except for the Polaris 600 HO CFI IQ and FST IQ at Pro Power Sports and Marine in Ramsey. Since we didn’t know how much gas was in the tanks in order to factor an accurate deduction, we filled each fuel cell to the bottom of its filler neck, then put it on the scales.

We multiplied Polaris ’ listed fuel capacity (11.7 gallons 600 CFI IQ; 10.2 gallons FST IQ) by 6.133 pounds per gallon of fuel and subtracted that amount from the figures recorded from the scales (569; 662 pounds) to get the corrected weights (497; 599 pounds).
