The amount of testing the lab does is almost mind-boggling. Just to satisfy the Environmental Protection Agency, BRP is required each quarter to test two motors from each of 12 engine families, pulled at random from the assembly line. The EPA requires all motors to stay within emissions compliance for 350 hours of use, which means BRP has had to conduct a “deterioration” test that measures emissions right after a two-hour break-in, and again after 350 hours of use. The regular emissions test takes about 90 minutes per motor, not including setup and teardown time, and two hours of break-in. The EPA will also randomly select for audit engines for “in use” testing that is done in the field. BRP will place these motors with a boater who will rack up hours in a hurry, usually a fishing guide or pro angler or police officer, and then get the motor back for testing after 175 hours of use.
